Among these cordless electric grease guns, I’d choose the DEWALT 20V MAX Kit as the best overall for buyers who want a familiar battery platform and a complete kit. The Milwaukee M18 2-Speed is a strong alternative for M18 owners who value speed control, while the Seesii 12000PSI model with two batteries stands out for buyers seeking an included-battery package. The main tradeoffs are tool-only versus kit, brand-battery compatibility versus included batteries, and higher pressure claims versus practical handling and hose reach. Grip style and trigger control also matter when fittings are awkward or lubrication runs are long. Read on for the full breakdown of all 15 options and guidance on choosing the right one for your equipment.

Key Takeaways
- The DEWALT 20V MAX Kit is the most rounded pick for shoppers who want a recognized platform with a battery and charger included; the tool-only DEWALT DCGG571B makes more sense for existing 20V owners.
- Battery ownership changes the value equation. Milwaukee M18 and DEWALT 20V models can be sensible tool-only buys if you already own compatible batteries, while several Seesii and other kits bundle batteries for buyers starting from scratch.
- Dual-grip designs address access, not just comfort. The Ecarke Milwaukee- and DeWalt-compatible models offer pistol and inline positions, which can help when fittings are difficult to reach.
- Pressure numbers alone do not rank the field. Multiple options advertise 12,000 PSI, so flow rate, trigger behavior, hose length, controls, and available batteries help separate them for actual work patterns.
- Included accessories vary in practical value. Longer hoses and multiple couplers can reduce setup friction, but buyers should check connector fit and grease-loading method rather than assuming every accessory suits their equipment.

More Details on Our Top Picks
CICZ 20V Cordless Electric Grease Gun, Tool Only
The CICZ is a sensible fit for buyers already invested in DeWalt 20V MAX batteries who want pressure for demanding fittings without adding another battery platform. Its variable-speed trigger gives more control over grease delivery than the DEKARTOL’s stated fixed maximum flow, which can help when a fitting needs careful application rather than rapid dispensing. The 39.4-inch hose and included couplers support reach across machinery, while the shoulder strap and case make transport and storage easier. The tradeoff is a 5.3 oz/min flow rate, slower than the DEKARTOL and Ecarke models at 8 oz/min. This is also a tool-only purchase, and its 10.12-pound weight still makes extended overhead work tiring. I’d choose it for controlled, occasional-to-regular maintenance, not maximum throughput.
Pros:- 12,000 PSI maximum pressure for demanding lubrication jobs
- Variable-speed trigger helps meter grease
- 39.4-inch hose and several included couplers support access to varied fittings
- Shoulder strap and carrying case aid transport and storage
Cons:- Battery and charger are not included
- 5.3 oz/min flow is slower than the DEKARTOL and Ecarke models’ stated 8 oz/min
- 10.12-pound weight can become tiring during prolonged use
Best for: DeWalt 20V MAX tool owners who service equipment and value trigger control, a long hose, and a carry case.
Not ideal for: Buyers without a compatible DeWalt battery, or high-volume users who want the faster stated flow of the DEKARTOL or Ecarke.
- Battery compatibility:DeWalt 20V MAX Lithium-Ion batteries
- Maximum pressure:12,000 PSI
- Flow rate:5.3 oz/min
- Hose length:39.4 inches
- Item weight:10.12 pounds
- Included accessories:Hose, extension pipe, 90° coupler adapter, 3 couplers, shoulder strap, carrying case
- Battery and charger:Not included
Our verdict“Choose the CICZ if you already own a DeWalt 20V MAX battery and prefer controlled grease delivery over the fastest flow.”
DEKARTOL 20V Cordless Grease Gun, 12,000 PSI, Tool Only
The DEKARTOL stands out for a stated 8 oz/min flow rate paired with 12,000 PSI, making it the speed-focused option among these DeWalt-compatible tools. That higher output may suit repeat servicing across multiple fittings better than the CICZ, whose stated rate is 5.3 oz/min. Its flexible 39.4-inch hose, rotating grip, and LED light address awkward or dim work areas, while support for cartridge and bulk grease gives buyers more loading choices. The cost of that versatility is a 10.36-pound tool-only setup: it is not a lightweight choice, and the battery is not included. The DEKARTOL also offers four couplers and a hard-shell case, but buyers should pick it for speed and loading flexibility rather than easy one-handed handling.
Pros:- 12,000 PSI maximum pressure and stated 8 oz/min flow
- Accepts 14 oz cartridges or bulk grease
- Rotating grip, flexible hose, and LED light help with difficult-to-reach fittings
- Includes four couplers, a shoulder strap, and a hard-shell case
Cons:- Battery is not included
- At 10.36 pounds, it is heavy for prolonged handheld use
- Its faster flow offers less emphasis on the lower-rate delivery listed for the CICZ
Best for: DeWalt 20V MAX owners who service many fittings and want fast flow plus cartridge-or-bulk loading.
Not ideal for: Buyers who need a complete battery kit or a lighter grease gun for extended handheld work.
- Battery compatibility:DEWALT 20V MAX
- Maximum pressure:12,000 PSI
- Flow rate:8 oz/min
- Grease loading:14 oz cartridges or bulk grease
- Grease compatibility:NLGI #0, #1, and #2
- Hose length:39.4 inches
- Weight:10.36 pounds
- Included accessories:Four couplers, shoulder strap, hard-shell case
Our verdict“Pick the DEKARTOL if fast dispensing and flexible grease loading matter more than low weight or an included battery.”
DEWALT 20V MAX Cordless Grease Gun Kit with 4.0Ah Battery and Charger
Unlike the CICZ and DEKARTOL tool-only options, this DEWALT includes a 4.0Ah battery and fast charger, so it makes a stronger case for buyers who are starting without a compatible pack. It pairs 10,000 PSI with a variable-speed trigger and a 42-inch hose, the longest listed here, giving the user reach and control for servicing equipment in cramped areas. The LED light helps when fittings are tucked into shadow, and the stated runtime of up to 16 cartridges per charge offers a useful planning reference. Its main compromise is 14.8 pounds, substantially heavier than the RYOBI P3410 at 8.3 pounds. Its 5 oz/min flow is also below the faster DEKARTOL and Ecarke figures. I’d favor this kit for a ready-to-work package, not for minimizing fatigue.
Pros:- Includes a 4.0Ah battery, fast charger, shoulder strap, and kit box
- 42-inch flexible hose reaches farther than the listed hoses on the other products here
- Variable-speed trigger and LED light support controlled work in low-light spaces
- Stated runtime is up to 16 cartridges per charge
Cons:- 14.8-pound weight is the heaviest among these five options
- 10,000 PSI maximum pressure is below the 12,000 PSI CICZ, DEKARTOL, and Ecarke figures
- Stated flow of up to 5 oz/min is slower than the faster-flow alternatives
Best for: Buyers who want a DeWalt-branded grease gun package with battery, charger, long hose, and work light included.
Not ideal for: Users who prioritize lighter handling or the 12,000 PSI and 8 oz/min figures offered by the DEKARTOL and Ecarke.
- Voltage:20V
- Battery:4.0Ah lithium-ion, included
- Maximum pressure:10,000 PSI
- Flow rate:Up to 5 oz/min
- Hose length:42 inches
- Weight:14.8 pounds
- Battery runtime:Up to 16 cartridges per charge
- Warranty:3-year limited
Our verdict“Choose this DEWALT kit when an included battery and charger matter more than low weight or maximum flow.”
Ecarke Cordless Grease Gun – 12,000 PSI, Dual Pistol/Inline Grip, Compatible with Milwaukee 18V Battery, 39″ Hose & 4 Couplers (Tool Only)
The Ecarke’s defining advantage is its pistol-or-inline grip, which gives Milwaukee 18V users more ways to hold the tool when access around a fitting is restricted. That makes it a more adaptable choice for changing positions than the DEKARTOL, whose listed features highlight a rotating grip instead. Ecarke also matches the DEKARTOL’s stated 12,000 PSI and 8 oz/min output, supports cartridge and bulk grease, and adds an LED work light. The 39-inch hose and four couplers round out a useful field setup. The drawbacks are substantial enough to shape the choice: it weighs 10.6 pounds, needs a compatible Milwaukee battery that is not included, and its hose is slightly shorter than the DEWALT kit’s 42 inches. I’d choose it for grip flexibility, not lighter handling.
Pros:- Dual pistol and inline grip modes adapt to different working angles
- 12,000 PSI maximum pressure and stated 8 oz/min flow
- Supports cartridge and bulk grease and includes four couplers
- LED light helps illuminate dim work areas
Cons:- Battery and charger are not included
- 10.6-pound weight can tire users during sustained work
- 39-inch hose is shorter than the DEWALT kit’s 42-inch hose
Best for: Milwaukee 18V owners who work around obstructed fittings and want pistol and inline grip positions.
Not ideal for: Buyers without a compatible Milwaukee battery or those who want an included power pack or the longest hose in this group.
- Battery compatibility:Milwaukee 18V lithium-ion
- Maximum pressure:12,000 PSI
- Flow rate:8 oz/min
- Hose length:39 inches
- Weight:10.6 pounds
- Grease loading:Cartridge and bulk grease
- Couplers included:4
- Battery and charger:Not included
Our verdict“Choose the Ecarke if you own Milwaukee 18V batteries and need grip options for obstructed or awkward fittings.”
RYOBI 18V Cordless Grease Gun P3410 (Tool Only)
At 8.3 pounds, the RYOBI P3410 is the lightest option in this five-product group, making it the clearest pick for buyers who want to reduce handling fatigue. Its 10,000 PSI maximum pressure is below the 12,000 PSI figures listed for the CICZ, DEKARTOL, and Ecarke, but it still offers a 7.5 oz/min flow rate—faster on paper than the DEWALT kit and CICZ. A 30-inch flexible hose is shorter than every other hose in this group, so it gives up reach compared with the DEWALT’s 42 inches and the roughly 39-inch alternatives. The LED light and plunger markings help with visibility and checking remaining grease. Like the tool-only CICZ, it requires a compatible battery; the P108 is not included. I’d pick it for lighter handling, not maximum pressure or reach.
Pros:- 8.3-pound weight is the lowest among these five products
- 7.5 oz/min maximum flow rate is faster than the listed CICZ and DEWALT figures
- LED work light supports use in dim areas
- Plunger markings help track grease remaining in the tube
Cons:- P108 battery is not included
- 30-inch hose is shorter than the hoses on the other four products
- 10,000 PSI maximum pressure is below the 12,000 PSI alternatives
Best for: RYOBI 18V owners who want a comparatively light grease gun for regular equipment maintenance.
Not ideal for: Buyers who need a battery in the box, a longer hose, or the 12,000 PSI maximum pressure listed by several alternatives.
- Voltage:18V
- Maximum pressure:10,000 PSI
- Maximum flow rate:7.5 oz/min
- Hose length:30 inches
- Weight:8.3 pounds
- Battery:P108 LITHIUM+ battery, not included
- Capacity per charge:Up to 19 grease cartridges
Our verdict“Choose the RYOBI P3410 if light handling and a 7.5 oz/min flow matter more than hose reach or maximum pressure.”
Seesii 12000PSI Electric Grease Gun Cordless, 3 Speed Control, 2 Batteries
I’d choose this Seesii when control over grease delivery matters as much as pressure. Its three speed settings range from 5 to 9 oz/min, letting me slow down for smaller fittings or move faster on routine service; the Seesii GR05 offers a fixed 5.8 oz/min instead. The included two 2.0Ah batteries and broad accessory kit suit users moving between machines, while the 39.4-inch hose, 90-degree adapter, and LED help with awkward or dimly lit fittings. It also supports cartridges and bulk grease, with a stated 14 oz capacity. The tradeoff is that its batteries are smaller than the J-KU’s two 4.0Ah packs, and the product description gives conflicting pressure figures: the title says 12,000 PSI, while the text also cites 10,000 PSI. I’d verify the rated pressure before buying for stubborn clogs.
Pros:- Three flow settings accommodate precision work and faster routine lubrication.
- Includes two batteries, reducing downtime while one pack charges.
- Long hose, 90-degree adapter, LED, and several couplers help reach difficult fittings.
- Supports cartridge and bulk loading.
Cons:- The product information gives conflicting maximum-pressure figures.
- Two 2.0Ah batteries offer less capacity per pack than the J-KU’s two 4.0Ah batteries.
- At 6.16 pounds before grease, it may feel cumbersome during prolonged overhead work.
Best for: Farm and equipment owners who service fittings of different sizes and want selectable flow plus a backup battery.
Not ideal for: Buyers who need a clearly specified pressure rating or longer battery capacity for extended heavy-duty work.
- Model:GR02 Utral
- Stated maximum pressure:12,000 PSI in title; description also states up to 10,000 PSI
- Flow rate:5, 7, or 9 oz/min
- Batteries:2 x 2.0Ah
- Hose length:39.4 inches
- Grease capacity:14 oz
- Grease loading:Cartridge or bulk
- Weight:6.16 pounds
Our verdict“Choose this Seesii for adjustable delivery and a well-equipped kit, but confirm its pressure specification if clearing stubborn fittings is the priority.”
Seesii 2-in-1 Electric Grease Gun, 12000 PSI, with 2 Batteries and 48” Hose
The standout here is reach: its 48-inch flexible hose gives me more room to position the gun away from obstructed fittings than the 39.4-inch hose on the Seesii GR02. That extra length can help around machinery where the body of the tool cannot sit close to the grease point. The stated 12,000 PSI pressure and 5.3 oz/min flow suit general heavy-equipment maintenance, and two 2.0Ah batteries plus a case make the kit practical to carry between jobs. It also supports bulk grease and standard 14 oz cartridges. Compared with the Seesii GR05, this model has a slightly slower listed flow rate but a longer hose. Its main compromise is a 6.6-pound tool weight, which can become tiring when the hose and gun must be held overhead; battery capacity may also call for charging breaks on larger routes.
Pros:- The 48-inch hose reaches farther than the 39.4-inch hoses on several other picks.
- Stated 12,000 PSI pressure and 5.3 oz/min flow support routine heavy-equipment greasing.
- Two 2.0Ah batteries and a carrying case are included.
- Works with bulk grease and standard 14 oz cartridges.
Cons:- The 6.6-pound tool can be tiring to hold for extended overhead work.
- Two 2.0Ah batteries may require charging breaks on extensive maintenance routes.
Best for: Mechanics and equipment operators who need extra hose reach around chassis, machinery, and obstructed fittings.
Not ideal for: Users doing prolonged overhead greasing or large service runs who need a lighter tool or higher-capacity batteries.
- Model:SE-GR01 Ultra
- Maximum pressure:12,000 PSI
- Flow rate:5.3 oz/min
- Batteries:2 x 2.0Ah rechargeable batteries
- Hose length:48 inches
- Grease loading:Bulk or standard 14 oz cartridge
- Weight:6.6 pounds
- Included feature:LED work light
Our verdict“Pick this Seesii when a 48-inch hose is more useful than the GR02’s adjustable speeds or the GR05’s slightly higher listed flow.”
Seesii Cordless Electric Grease Gun, 10,000 PSI, 5.8 oz/min, with Lock-On Trigger
I’d put the Seesii GR05 on the shortlist for jobs where repeated trigger pulls become tedious. Its lock-on trigger keeps grease flowing without constant finger pressure, and the stated 5.8 oz/min rate is a little faster than the SE-GR01 Ultra’s 5.3 oz/min. The 48-inch hose, LED, and four coupler options also make it adaptable around varied fittings, while bulk, cartridge, and suction loading offer more filling choices than the cartridge-and-bulk setup listed for the SE-GR01 Ultra. The tradeoff is pressure: its 10,000 PSI rating is below that model’s 12,000 PSI, so I’d favor the SE-GR01 for work where maximum stated pressure is the priority. This GR05 includes one 2.0Ah battery, with a listed output of up to six 14 oz cartridges per charge, and its source listing gives an incomplete weight unit.
Pros:- Lock-on trigger supports continuous greasing without holding the trigger by hand.
- 48-inch hose and four coupler options accommodate varied fitting access.
- Bulk, cartridge, and suction loading provide multiple refill methods.
- Listed battery output is up to six full 14 oz cartridges per charge.
Cons:- Its 10,000 PSI rating is lower than the 12,000 PSI SE-GR01 Ultra.
- Only one 2.0Ah battery is listed as included.
- The product listing gives an incomplete unit for the 8.2 weight figure.
Best for: Maintenance workers who grease many fittings in sequence and value hands-free trigger operation and flexible loading.
Not ideal for: Buyers prioritizing the highest listed pressure, a second included battery, or a fully specified tool weight.
- Model:GR05
- Maximum pressure:10,000 PSI
- Flow rate:5.8 oz/min
- Hose length:48 inches
- Battery:2.0Ah
- Battery output:Up to 6 full 14 oz grease cartridges per charge
- Grease compatibility:NLGI #0, #1, and #2
- Loading methods:Bulk, cartridge, and suction
Our verdict“Choose the GR05 for lock-on operation and flexible filling methods, not for maximum pressure or a two-battery kit.”
Bluebow Electric Grease Gun Kit – 12,000 PSI, 5.3 oz/min Flow, Dual 4000 mAh Batteries, 39.4″ Flexible Hose, Lightweight Teal
The Bluebow’s strongest on-paper advantage is its two 4,000mAh batteries, which offer twice the stated capacity per pack of the 2.0Ah batteries supplied with the Seesii SE-GR01 Ultra. That makes this a more appealing kit for longer stretches away from a charger, although the listing does not give a runtime figure. Its 12,000 PSI rating and 5.3 oz/min flow match the SE-GR01’s listed pressure and flow, while the 39.4-inch hose is shorter than that Seesii’s 48-inch reach. An air-bleeder valve and carrying case add practical touches, but the listed weight is 11.77 pounds—far heavier than the other Seesii kits—so I would not choose it for frequent overhead work. The dimensions supplied are unusually large for a handheld tool, another detail I’d verify with the seller before purchase.
Pros:- Two 4,000mAh batteries have greater stated capacity than the 2.0Ah packs in the Seesii kits.
- 12,000 PSI pressure and 5.3 oz/min flow suit heavy-equipment lubrication.
- Air-bleeder valve and carrying case support setup and transport.
- Ergonomic one-handed grip is intended for controlled handling.
Cons:- Listed weight of 11.77 pounds is high for extended handheld or overhead use.
- The 39.4-inch hose is shorter than the Seesii SE-GR01 Ultra’s 48-inch hose.
- No battery runtime or charging-time information is provided, and listed dimensions warrant verification.
Best for: Farm or construction operators seeking a kit with two higher-capacity batteries for work away from a charger.
Not ideal for: Buyers who need a light handheld tool, a longer hose, or dependable runtime and size information before purchase.
- Model:HYQ-MS-01
- Maximum pressure:12,000 PSI
- Flow rate:5.3 oz/min
- Batteries:2 x 4,000mAh
- Hose length:39.4 inches
- Weight:11.77 pounds
- Dimensions:30 x 40 x 65 inches, as listed
- Color:Teal
Our verdict“Consider the Bluebow for its higher-capacity battery pair, provided its substantial listed weight and unclear runtime fit your work.”
J-KU Cordless Electric Grease Gun Kit, 12,000 PSI, 2 Batteries
The J-KU is the most accessory-heavy choice in this group, with two 4.0Ah batteries, three couplers, a 90-degree adapter, gloves, a shoulder strap, hose organizer, and case. That bundle is more expansive than the Seesii SE-GR01 Ultra’s kit, though the Seesii has a longer 48-inch hose versus this model’s 39.4 inches. The J-KU’s 12,000 PSI rating and 5.3 oz/min flow suit demanding routine lubrication, and its two power modes provide some control over different tasks. It accepts standard 14 oz cartridges or up to 400 ml of bulk grease. The central drawback is weight: at 13.11 pounds, it is substantially heavier than either Seesii option, making extended handheld work less appealing. Its stated compatibility with Ma-kita 18V systems is also narrower than a broadly specified battery platform.
Pros:- Includes two 4.0Ah batteries, matching the Bluebow’s stated battery capacity per pack.
- Two power modes offer more task flexibility than a single-speed setup.
- Three couplers, a 90-degree adapter, LED, gloves, strap, organizer, and case are included.
- Supports standard 14 oz cartridges and up to 400 ml of bulk grease.
Cons:- At 13.11 pounds, it is heavier than the Seesii kits and may tire users during extended handheld work.
- Its 39.4-inch hose is shorter than the 48-inch Seesii SE-GR01 Ultra and GR05 hoses.
- Battery compatibility is specified for Ma-kita 18V systems.
Best for: Equipment owners who want a ready-to-work kit with two higher-capacity batteries and accessories for varied fittings.
Not ideal for: Technicians who frequently work overhead, need a lighter tool, or want a longer hose than 39.4 inches.
- Maximum pressure:12,000 PSI
- Flow rate:5.3 oz/min
- Batteries:2 x 4.0Ah
- Battery compatibility:Ma-kita 18V systems
- Hose length:39.4 inches
- Grease capacity:Standard 14 oz cartridge or up to 400 ml bulk grease
- Grease type:NLGI #2
- Weight:13.11 pounds
- Features:Two power modes, 90-degree coupler, quick-release coupler, and LED light
Our verdict“Choose the J-KU for its two 4.0Ah batteries and extensive accessory bundle if its 13.11-pound weight is manageable for your work.”
Ecarke Cordless Grease Gun Compatible with DeWalt 20V Battery, 12000 PSI Max Electric Grease Gun, Dual Pistol & In-Line Grip, Works with Bulk & Cartridge Grease, with 39″ Hose & 4 Couplers (Tool Only)
The Ecarke stands out for combining 12,000 PSI pressure and a listed 8 oz/min flow rate with a handle that switches between pistol and in-line grips. That flexibility can help when access or working angle changes; the Milwaukee M18, by comparison, offers dual-speed control but not a documented two-position grip. Ecarke also accepts bulk or cartridge grease and includes four couplers, a shoulder strap, and a case, making it a well-equipped choice for varied service work. The tradeoff is that this is a tool-only DeWalt 20V-compatible model, so its kit is less ready to use if you do not already own a compatible battery and charger. At 10.41 pounds, it is also a substantial tool to carry through a long maintenance round.
Pros:- Listed 12,000 PSI maximum pressure and 8 oz/min flow rate support demanding, faster greasing tasks.
- Pistol and in-line grip options suit changing access angles.
- Accepts bulk grease and cartridges and includes four couplers.
- Includes a 39-inch hose, LED light, shoulder strap, and hard case.
Cons:- Battery and charger are not included; operation depends on compatible DeWalt 20V batteries.
- Listed weight of 10.41 pounds may feel tiring during prolonged use.
Best for: Equipment technicians who already own compatible DeWalt 20V batteries and need to switch grip styles or grease-loading methods across jobs.
Not ideal for: Buyers without DeWalt 20V batteries or anyone prioritizing a lighter tool for extended overhead work.
- Maximum pressure:12,000 PSI
- Flow rate:8 oz/min
- Battery compatibility:DeWalt 20V lithium-ion batteries, DCB200–DCB206
- Grease loading:Bulk and cartridge grease
- Hose length:39 inches
- Grip modes:Pistol and in-line
- Item weight:10.41 pounds
- Included accessories:Four couplers, shoulder strap, hard case
Our verdict“Choose the Ecarke if you own DeWalt 20V batteries and value its grip options and high listed flow rate more than a lighter build.”
Alloyman HYQ-03 2-in-1 Cordless Grease Gun Kit with Two 4.0 Ah Batteries
The Alloyman is the clearest pick here for buyers who need a battery-ready kit: it includes two 4.0 Ah batteries, while the Ecarke and Milwaukee M18 options require a separately sourced compatible battery. Its 12,000 PSI rating, pistol and straight modes, and 39.4-inch hose make it adaptable to different fittings and working positions. The listed 5.3 oz/min flow is more modest than Ecarke’s claimed 8 oz/min, so I’d favor Alloyman for a supplied power setup and flexible handling rather than the quickest stated output. It supports bulk grease and cartridges and adds an LED light plus IP54 splash and dust protection. The main compromise is its 12.78-pound weight, which makes it a less appealing choice for frequent carrying or prolonged overhead work.
Pros:- Includes two 4.0 Ah batteries, unlike the tool-only Ecarke and Milwaukee M18 models.
- Pistol and straight operating modes accommodate different working positions.
- Supports bulk and cartridge grease and includes a 39.4-inch flexible hose.
- IP54 protection, LED light, and a 365-day warranty are specified.
Cons:- At 12.78 pounds, it is the heaviest listed option in this group.
- Its 5.3 oz/min stated flow rate is lower than the Ecarke’s 8 oz/min claim.
Best for: Farm, fleet, or workshop owners who want two batteries included and need a grease gun for varied fittings and working positions.
Not ideal for: Buyers who prioritize low carry weight or want the higher listed flow rate of the Ecarke.
- Maximum pressure:12,000 PSI
- Flow rate:5.3 oz/min
- Operating modes:Pistol and straight
- Batteries:Two 4.0 Ah batteries
- Hose length:39.4 inches
- Grease capacity:600 cc bulk; supports 114 oz cartridges, 53 mm diameter
- Item weight:12.78 pounds
- Protection and warranty:IP54; 365 days
Our verdict“Pick the Alloyman if you want two batteries in the kit and can accept a heavier tool for the convenience of a ready-to-work setup.”
TaskStar Cordless Electric Grease Gun with Lock-On Trigger
At 5.6 pounds in the description, the TaskStar is the portability pick in this group; even the product information’s alternate 6.16-pound figure stays below the listed weights of the Milwaukee M18 and DEWALT DCGG571B. Its lock-on trigger can keep grease flowing without continuous finger pressure, while two included batteries and a 40-inch hose help support longer service sessions. The tradeoff is a lower stated maximum pressure of 10,000 PSI, compared with 12,000 PSI for the Alloyman and Ecarke. Its 5 oz/min flow rate is also more restrained than Ecarke’s listed figure. That makes TaskStar better suited to routine maintenance where manageable carry weight matters than to buyers chasing the highest stated pressure or output. The weight discrepancy is worth checking before purchase.
Pros:- Listed at 5.6 pounds in the description, lighter than the Milwaukee M18 and DEWALT options in this group.
- Lock-on trigger supports continuous greasing with less trigger pressure.
- Includes two rechargeable lithium-ion batteries and a 40-inch hose.
- LED light and shoulder strap support portable maintenance work.
Cons:- Maximum pressure is 10,000 PSI, below the 12,000 PSI Ecarke and Alloyman ratings.
- Product information gives conflicting weights of 5.6 and 6.16 pounds.
Best for: Mobile mechanics and equipment owners who carry a grease gun between service points and value a lighter listed weight with batteries included.

Our verdict“Choose the TaskStar for portable routine greasing and included batteries, but look to the Ecarke or Alloyman if maximum stated pressure matters more.”
Milwaukee M18 2-Speed Grease Gun (Model 2646-20)
The Milwaukee M18 is the control-focused choice: its two-speed design lets the operator favor pressure or flow, a different approach from the DEWALT DCGG571B’s variable-speed trigger. That distinction may suit users who want selectable operating modes rather than adjusting speed continuously at the trigger. It delivers up to 10,000 PSI and pairs that with a 48-inch hose, the longest listed here, for reaching awkward fittings. A lock-on/lock-off trigger and onboard LED add practical control in work areas with poor visibility. The cost of this reach and established M18 battery platform is a 9-pound tool-only setup: the battery is not included, and the Ecarke claims higher maximum pressure. I’d favor it for M18 owners who value hose reach and speed selection, not buyers seeking the lightest or highest-pressure option.
Pros:- Two-speed operation provides a choice between pressure and flow.
- 48-inch flexible hose is the longest specified among these five products.
- Lock-on/lock-off trigger and LED light support controlled work in dim spaces.
- Uses the Milwaukee M18 lithium-ion battery system.
Cons:- M18 battery is not included.
- Listed weight is 9 pounds, which can contribute to fatigue during extended use.
- 10,000 PSI maximum is below the 12,000 PSI Ecarke and Alloyman ratings.
Best for: M18 platform owners servicing machinery with hard-to-reach fittings who want selectable pressure-or-flow operation.
Not ideal for: Buyers without an M18 battery, those seeking the highest listed pressure, or anyone who wants a lighter tool for extended use.
- Model:2646-20
- Maximum pressure:10,000 PSI
- Power source:Cordless, 18 volts
- Speed settings:Two-speed operation
- Hose length:48 inches
- Item weight:9 pounds
- Battery system:Milwaukee M18 lithium-ion; battery not included
- Warranty:5 years
Our verdict“Choose the Milwaukee if you already own M18 batteries and want a long hose with two-speed control, rather than maximum pressure or low weight.”
DEWALT 20V MAX Cordless Grease Gun, 42-Inch Hose, 10,000 PSI (DCGG571B)
The DEWALT DCGG571B suits users who want to modulate grease flow at the trigger rather than choose between set speeds. Its variable-speed trigger offers finer control than the Milwaukee M18’s two-speed system, while an integrated foot gives the tool a place to rest on a flat surface between fittings. The 42-inch hose is shorter than Milwaukee’s 48-inch line but still helps reach difficult points, and the air-bleeder valve adds a useful feature for priming. Its 10,000 PSI maximum and 5 oz/min flow are below the Ecarke’s stated pressure and flow figures, so it is not the pick for maximum output on paper. The battery is not listed among included components, making it most practical for owners already invested in DEWALT 20V MAX.
Pros:- Variable-speed trigger allows the operator to adjust grease delivery.
- Integrated foot provides a resting point on flat surfaces.
- 42-inch flexible hose and LED work light aid access and visibility.
- Air-bleeder valve is specified for the tool.
Cons:- Battery is not listed among the included components.
- 10,000 PSI maximum is below the 12,000 PSI Ecarke and Alloyman ratings.
- Its 42-inch hose is shorter than the Milwaukee M18’s 48-inch hose.
Best for: DEWALT 20V MAX owners who service equipment with varied fittings and want trigger-based flow control plus an integrated resting foot.
Not ideal for: Buyers who need batteries included, the longest hose, or a higher stated pressure and flow rate than the Ecarke offers.
- Model:DCGG571B
- Maximum pressure:10,000 PSI
- Maximum flow rate:5 oz/min
- Power source:Battery powered
- Hose length:42 inches
- Item weight:8 pounds
- Special features:Variable-speed trigger, LED light, integrated foot, air-bleeder valve
- Warranty:3-year limited warranty
Our verdict“Pick the DEWALT if you own compatible 20V MAX batteries and value variable trigger control and a resting foot over higher pressure or a longer hose.”
How We Picked
I compared the 15 cordless electric grease guns by the details that shape ownership: stated pressure and flow, battery and charger inclusion, compatibility with established battery platforms, hose reach, grip options, trigger and speed controls, and support for cartridge or bulk grease where specified. I also separated complete kits from tool-only listings, since the latter can be a poor fit for a first-time buyer but a sensible choice for someone already invested in a battery system. A high pressure figure is useful context, but it does not by itself indicate easier servicing or better control.
The ranking gives the strongest weight to a balanced package, clear practical advantages, and a straightforward fit for a defined buyer. That puts the DEWALT kit near the top as a well-rounded ready-to-use choice, while Milwaukee ranks strongly for M18 owners seeking two-speed operation. The Seesii battery-included models and dual-grip Ecarke options stand out for different needs, but kit contents, brand-platform fit, and varying feature sets keep them from being interchangeable. I ranked models with less clearly differentiated specifications lower, not because they cannot suit a buyer, but because the supplied details offer fewer grounds to prefer them over better-defined alternatives.
Factors to Consider When Choosing Cordless Electric Grease Guns
I’d narrow the choice by matching the gun to your service routine before comparing headline PSI. The factors below help prevent common mismatches, especially around batteries, fittings, grease loading, and the physical space around service points.
Match the Battery Strategy to Your Workshop
Start with the batteries already on your shelf, then check the product’s exact platform compatibility. A tool-only model can reduce duplication if you own the matching DEWALT 20V or Milwaukee M18 batteries, but a similar voltage label does not mean batteries interchange across brands. If this is your first cordless grease gun, compare the full kit contents: battery capacity, charger inclusion, and whether the package supplies one or two batteries. A spare battery matters most when you service equipment across several locations or cannot pause to recharge. For occasional maintenance near a charger, a single included battery may be enough. I would not buy a tool-only model on the assumption that an adapter will be a dependable substitute for the specified battery system.
Treat Pressure and Flow as Different Questions
Maximum pressure describes a stated capability, while flow rate points more directly to how quickly grease can be delivered. Many guns in this roundup claim up to 12,000 PSI, so that figure alone does little to distinguish them. A higher-flow specification can matter when servicing numerous fittings, but faster delivery can make control more important on small or delicate applications. Speed settings or a lock-on trigger may suit repetitive work, yet they can feel less useful when each fitting needs a short, measured shot. Match the gun’s rated performance to the equipment’s lubrication requirements rather than assuming the largest number is automatically the best fit. If the manufacturer of your machinery specifies a pressure limit or lubrication method, follow that guidance.
Check Hose Reach Against Real Access Points
Measure the distance from where you can safely hold the tool to the hardest-to-reach fitting, including obstacles that force a bend in the hose. A longer hose, such as the 42- or 48-inch options listed here, can help reach behind components, but added length can also be harder to manage in a crowded space. A shorter hose may be easier to control when fittings are close and visible. Flexible reach is only useful if the coupler seats securely and the hose can be routed without kinking. Before buying, note whether your work is mostly on open machinery, vehicle undercarriages, farm equipment, or tight assemblies. This measurement often matters more than small differences in advertised pressure.
Choose a Grip and Trigger for Your Work Pattern
Pistol grips can feel natural for one-handed positioning, while an inline grip may make it easier to line up with fittings in narrow or awkward spaces. Dual-grip designs give more positioning options, but they do not remove the need to support the gun and hose during use. A lock-on trigger can reduce repeated finger pressure during longer runs; for intermittent lubrication, a conventional trigger may make short applications easier to manage. Speed controls offer another way to tailor delivery, although extra controls are useful only if they are easy to reach while holding the tool. Think about how often you move between fittings and whether you need steady output or careful bursts. If possible, weigh and handle a comparable tool before committing, since a battery and grease-filled barrel add to the working load.
Confirm Grease Loading and Coupler Fit
Do not assume that every electric grease gun loads the same way or accepts the grease supply you already use. Check the model’s stated support for cartridges, bulk grease, or both, and verify that its loading method matches your shop routine. Switching between grease types can be a problem if equipment needs a specific formulation, so keep labels and maintenance instructions in view. Included couplers are useful only when they fit your fittings and release cleanly; extra pieces in a kit do not guarantee compatibility with every machine. A coupler that locks on securely can save time, but one that is difficult to remove can disrupt work. Confirm replacement hose and coupler availability before buying if the gun will be used regularly.
Pay for Features You Will Use, Not a Bigger Spec Sheet
Higher capability is worthwhile when your equipment, service volume, or access problems call for it, not simply because a listing has a larger number. A second battery can be more valuable than extra pressure for a mobile crew that cannot stop work to recharge. A long hose or alternate grip may matter more than speed controls when fittings sit behind guards or frames. Conversely, occasional home or workshop maintenance may not justify a feature-rich kit if a straightforward model covers the task. Compare what is included and what you already own, since buying a charger or battery twice can change the practical value of a package. My rule is to pay extra for a solution to a recurring service bottleneck, not for a feature that will remain unused.
Frequently Asked Questions
Should I buy a tool-only grease gun or a kit with batteries?
I’d choose tool-only when I already own batteries and a charger confirmed for that exact platform. For a first cordless grease gun, a kit avoids a separate battery purchase and gives you a known starting setup. Check whether the kit includes a charger as well as batteries, and compare battery capacity and quantity against the length of your typical service session. Two batteries can reduce interruptions on mobile or high-volume work, while a single battery may be adequate for occasional maintenance. Do not rely on voltage alone to confirm compatibility between brands or product generations.
Is a 12,000 PSI model necessarily better than a 10,000 PSI model?
No; maximum pressure is only one part of choosing a grease gun. The equipment being serviced determines the pressure and lubrication method you need, and the gun’s stated maximum does not prove it will be easier to control. Flow rate, trigger response, hose routing, and coupler fit affect how the tool feels in routine use. A model with a lower stated maximum may be a better match for your maintenance tasks if its controls and setup suit them. Check your equipment guidance rather than selecting solely by the highest pressure claim.
When is a dual-grip grease gun worth choosing?
A dual-grip model is most useful when your fittings sit in a mix of open and restricted positions. Switching between pistol and inline holds can help align the hose without forcing an awkward wrist angle. It may be less valuable if nearly all your fittings are easy to reach from one position, since the extra grip choice will not change the job much. Grip flexibility also does not replace adequate hose length or a compatible coupler. I’d prioritize it for varied equipment and tight access, then confirm that the tool remains manageable with its battery and grease load.
Do I need a longer hose, or can a standard hose handle most jobs?
The right hose length depends on how far you need to reach while keeping the tool in a stable position. A longer hose can help with fittings behind frames or guards, but it can be harder to guide and store in confined work areas. A shorter hose can offer a tidier setup when fittings are exposed and close by. Measure your most difficult access point and allow for the route around obstructions, rather than measuring straight-line distance alone. Also check that the supplied hose and coupler match your fittings and can be replaced if damaged.
Are two included batteries more useful than speed control?
That depends on whether downtime or delivery control is the bigger issue in your work. Two batteries are helpful for long service days or when charging is not available near the equipment. Speed control can be more valuable when you switch between tasks that call for different delivery rates or want to manage output more deliberately. For intermittent maintenance, a single battery may last through the job, making control features the more useful distinction. I’d estimate how many fittings you service per session and whether you have a chance to recharge before choosing between those benefits.
Conclusion
For the best overall, I’d start with the DEWALT 20V MAX Cordless Grease Gun Kit because it presents a balanced, battery-included option. The best value for existing platform owners is the tool-only DEWALT DCGG571B or Milwaukee 2646-20, depending on whether your batteries are DEWALT 20V or M18; the Milwaukee is the stronger fit if two-speed operation is a priority. For a ready-to-go kit with spare power, consider the Seesii 12000PSI model with two batteries, and for beginners I’d favor a bundle that includes the battery and charger rather than a bare tool. If your work involves awkward fittings, look at the Ecarke dual-grip models and choose the version compatible with your battery system. Match your final pick to your battery inventory, access needs, and grease-loading routine rather than choosing by PSI alone.
