A battery-powered grease gun kit can save time on frequent lubrication, but battery compatibility, hose reach, and included accessories make a real difference. My best overall pick is the DEWALT 20V MAX Cordless Grease Gun Kit, which pairs a familiar platform with a battery and charger in the box. The SOARFLY 2-in-1 stands out for grip flexibility, while the ELECDIYER 16,000 PSI is the high-pressure option for buyers who need that specification and already have compatible DeWalt batteries. The main tradeoffs are kit completeness versus tool-only value, and a longer hose or higher pressure versus weight and handling. Read on for the full breakdown and a guide to matching a kit to your equipment and workload.

Key Takeaways
- The DEWALT 20V MAX kit is the clearest ready-to-work choice: it includes a 4.0Ah battery and charger, unlike the bare-tool options that require a compatible battery purchase or an existing one.
- Grip style is a practical separator: SOARFLY, Alloyman, and the Seesii 2-in-1 model offer pistol and in-line configurations, which can help when access angles change during a job.
- A higher PSI figure is not the whole performance story: ELECDIYER lists 16,000 PSI, but buyers should also weigh compatibility, hose, control, and whether their equipment calls for that pressure.
- Two-battery kits suit longer work sessions: Seesii, J-KU, Alloyman, and Bluebow include two batteries, while a single included battery can make a simpler, lighter setup.
- Hose length and included couplers affect reach and readiness: the 48-inch Seesii and 42-inch DEWALT tool offer added reach, while some options list four couplers for broader connection coverage.

More Details on Our Top Picks
Cordless Grease Gun Compatible with DeWalt 20V Battery, 12000 PSI Electric Grease Gun Kit, Dual Pistol & In-Line Grip, 39″ Hose & 4 Couplers (Bare Tool)
This bare tool makes the strongest case for buyers who already own batteries in the DeWalt 20V platform. Its listed 8 oz/min flow rate is higher than the 5.3 oz/min figures given for the Orion Motor Tech and SOARFLY, which may help when servicing several fittings in a row. The pistol or in-line grip also gives more choice when access or hand position changes, and an LED helps in poorly lit work areas. The tradeoff is that the battery and charger are not included, so it is a less complete kit than the SOARFLY, which arrives with two batteries. At 5.64 pounds, it is lighter than several bundled options here, but it still adds weight during overhead or extended greasing. I’d shortlist it for DeWalt owners who value speed over an all-in-one package.
Pros:- Listed 8 oz/min flow rate is the highest in this five-product group
- Uses compatible DeWalt 20V lithium-ion batteries
- Handle switches between pistol and in-line grips
- Includes an LED work light and four couplers
Cons:- Battery and charger are not included
- Limited to the stated DeWalt 20V battery platform
- 5.64-pound tool weight may tire users during long sessions
Best for: Equipment owners with compatible DeWalt 20V batteries who want a fast-flowing grease gun and flexible grip positions.
Not ideal for: First-time cordless-tool buyers without a DeWalt 20V battery and charger, or anyone wanting a ready-to-run kit.
- Maximum pressure:12,000 PSI
- Flow rate:8 oz/min
- Battery compatibility:DeWalt 20V lithium-ion batteries; battery not included
- Hose length:39 inches
- Couplers included:4
- Grease loading:14 oz cartridge or bulk grease
- Weight:5.64 pounds
- Handle positions:Pistol and in-line
Our verdict“Choose this bare tool if you already own compatible DeWalt 20V batteries and want the group’s fastest listed flow rate.”
Orion Motor Tech 12,000 PSI Cordless Grease Gun, Tool Only
The Orion Motor Tech suits buyers who already have a compatible aftermarket Makita-interface battery and want a tool-only option. It reaches 12,000 PSI and lists a 5.3 oz/min flow rate, matching the SOARFLY’s stated flow while offering a 39.4-inch hose and 90-degree coupler for awkward fittings. Its adjustable pistol or straight in-line handle adds useful positioning flexibility. The compatibility caveat matters: the listing says it does not work with original Makita batteries, so the platform name alone is not enough to confirm a fit. Compared with the battery-included SOARFLY and Seesii, this is a less complete purchase, and its listed 10-pound weight makes it a substantial tool to hold. I’d pick it only when the battery fit is verified and an all-in-one kit is not needed.
Pros:- Provides up to 12,000 PSI for demanding fittings
- 39.4-inch hose and included 90-degree coupler support awkward access
- Handle adjusts between pistol and straight in-line positions
- Accepts 14 oz cartridges or bulk suction loading
Cons:- Battery is not included
- Not compatible with original Makita batteries, despite the interface description
- Listed 10-pound weight is higher than the bare-tool DeWalt-compatible option
Best for: Owners of a verified compatible aftermarket 18V/20V Makita-interface battery who want to reuse it for equipment lubrication.
Not ideal for: Makita tool owners relying on original Makita batteries, or buyers who need batteries and a charger included.
- Maximum working pressure:12,000 PSI
- Flow rate:Up to 5.3 oz/min
- Grease capacity:14 oz cartridge or bulk suction loading
- Hose length:39.4 inches
- Battery compatibility:Generic aftermarket 18V/20V Makita-interface batteries; not original Makita batteries
- Handle positions:Pistol and straight in-line
- Included coupler:90-degree coupler
- Weight:10 pounds
Our verdict“Buy the Orion only if you have confirmed access to a compatible aftermarket battery and prefer a tool-only setup.”
SOARFLY 2-in-1 Cordless Electric Grease Gun Kit, 12,500 PSI
For a buyer starting without compatible batteries, the SOARFLY is the most self-contained choice in this group: it includes two 2.0Ah batteries, a charger-ready kit setup, a case, and several application accessories. Its 12,500 PSI maximum is the highest stated pressure among these five products, while the 5.3 oz/min flow rate is more modest than the DeWalt-compatible tool’s listed 8 oz/min. That makes it a better fit for buyers prioritizing pressure and an included power supply than the quickest servicing pace. The 500cc barrel accepts standard 14 oz cartridges or bulk grease and is specified for NLGI #0, #1, and #2. The cost of that completeness is heft: at 11.53 pounds, it is much heavier than the Seesii. I’d favor it for stationary or intermittent heavy-equipment maintenance over frequent overhead work.
Pros:- Highest stated maximum pressure in this group at 12,500 PSI
- Includes two 2.0Ah batteries
- Supports 14 oz cartridges, bulk grease, and NLGI #0–2
- Package includes a case, hose, locking coupler, and multiple nozzle accessories
Cons:- 11.53-pound weight can make extended use tiring
- Listed 5.3 oz/min flow is slower than the DeWalt-compatible option’s 8 oz/min
- Battery must be properly installed for operation
Best for: Farm, truck, and heavy-equipment owners who need an included battery setup, broad grease-loading options, and a high stated pressure limit.
Not ideal for: Users who frequently work overhead or need a lighter gun for long maintenance rounds.
- Maximum pressure:12,500 PSI
- Flow rate:5.3 oz/min
- Batteries:Two 2.0Ah rechargeable batteries
- Hose length:39.4 inches
- Barrel capacity:500cc
- Grease compatibility:NLGI #0, #1, and #2
- Loading options:14 oz cartridges or bulk grease
- Weight:11.53 pounds
Our verdict“Choose the SOARFLY if you want a high-pressure, battery-included kit for heavy equipment and can manage its substantial weight.”
Seesii Cordless Electric Grease Gun with 3-Speed Control and Two Batteries
The Seesii’s distinction is three selectable flow settings, listed as 5, 7, and 9 oz/min. That gives buyers more control over pace than the fixed-flow SOARFLY or Orion Motor Tech, which may help when switching between routine fittings and jobs that call for faster dispensing. It also includes two 2.0Ah batteries, a charger, case, shoulder strap, and several adapters, making it a more complete purchase than the bare-tool DeWalt-compatible model. There is a significant specification mismatch, though: the data lists maximum pressure as up to 10,000 PSI while the title states 12,000 PSI. I would not choose it based on the higher figure without clarification. Its 6.16-pound weight is comparatively manageable, but the battery compatibility details are less clear than the DeWalt tool’s stated platform fit.
Pros:- Three listed flow settings: 5, 7, and 9 oz/min
- Includes two 2.0Ah batteries, charger, and carrying case
- 39.4-inch hose and included adapters support different access angles
- Listed 6.16-pound weight is lower than the other battery-included options here
Cons:- Maximum pressure is inconsistent between the product title and specifications
- Battery interchange details are not provided
- The 2.0Ah batteries may require more frequent changes during extended work than higher-capacity packs
Best for: Maintenance users who want included batteries and selectable flow speeds for a mix of routine and faster lubrication jobs.
Not ideal for: Buyers who need an unambiguous pressure rating or require confirmed compatibility with a specific Makita battery.
- Maximum pressure:Up to 10,000 PSI in specifications; title states 12,000 PSI
- Speed settings:3
- Listed flow rates:5, 7, and 9 oz/min
- Batteries:Two 2.0Ah batteries
- Hose length:39.4 inches
- Grease capacity:14 oz
- Grease compatibility:NLGI #0–2
- Weight:6.16 pounds
- Included accessories:Charger, couplers, adapters, extension pipe, shoulder strap, and case
Our verdict“Pick the Seesii for adjustable dispensing and a relatively light, battery-included kit, but confirm its pressure rating and battery fit first.”
J-KU Cordless Electric Grease Gun Kit, 12,000 PSI, with Two 4.0Ah Batteries
The J-KU is aimed at buyers who want more battery capacity in the box: its two 4.0Ah batteries have twice the stated capacity of the 2.0Ah packs supplied with the SOARFLY and Seesii. That may reduce interruptions for charging or pack changes during longer maintenance rounds, though actual runtime is not specified. It lists 12,000 PSI and 5.3 oz/min, matching the Orion Motor Tech’s stated output figures while offering batteries, charger, gloves, shoulder strap, and a case. Its 39.4-inch hose and 90-degree adapter help reach restricted fittings. The tradeoff is considerable heft at 13.11 pounds, the heaviest listed product in this group, and the battery fit is described only as compatible with Makita 18V systems. I’d favor it over the Orion when included high-capacity batteries matter, but not for users prioritizing low carry weight.
Pros:- Includes two 4.0Ah batteries, higher stated capacity than the 2.0Ah packs in the SOARFLY and Seesii kits
- Provides 12,000 PSI maximum pressure and 5.3 oz/min flow
- Accepts standard 14 oz cartridges or up to 400 ml of bulk grease
- Includes a 39.4-inch hose, 90-degree adapter, quick-release coupler, gloves, and case
Cons:- 13.11-pound weight is the highest in this five-product group
- Battery compatibility description does not clarify original Makita battery support
- Flow rate is lower than the 8 oz/min listed for the DeWalt-compatible tool
Best for: Operators doing extended equipment-maintenance rounds who want two higher-capacity batteries and a bundled accessory set.
Not ideal for: Users who need a lightweight grease gun or require clearly specified compatibility with original Makita batteries.
- Maximum pressure:12,000 PSI
- Flow rate:5.3 oz/min
- Batteries:Two 4.0Ah batteries
- Grease capacity:14 oz cartridge or up to 400 ml bulk grease
- Hose length:39.4 inches
- Battery compatibility:Described as compatible with Makita 18V systems
- Features:Two power modes, LED light, 90-degree adapter, quick-release coupler
- Weight:13.11 pounds
- Included accessories:Charger, gloves, shoulder strap, and carrying case
Our verdict“Choose the J-KU for bundled 4.0Ah batteries and extended maintenance sessions if its weight and battery compatibility suit your setup.”
TaskStar Cordless Electric Grease Gun with Lock-On Trigger
The TaskStar’s lock-on trigger is its clearest distinction: it can keep grease flowing without requiring constant trigger pressure, which may be useful across repeated fittings on tractors or machinery. Its stated 10,000 PSI pressure and 5 oz/min flow put it in the same output class as the DEWALT 20V MAX kit, while its included pair of rechargeable batteries offers a spare without relying on a separate battery platform. The 40-inch hose, LED light, and shoulder strap support mobile service work. The tradeoff is that the DEWALT lists a longer 42-inch hose and a 4.0Ah battery, while TaskStar’s battery capacity is not specified. Its weight also varies between the description and product information, so buyers who prioritize a precise carry weight should look elsewhere.
Pros:- Lock-on trigger supports continuous greasing without holding the trigger throughout each task.
- Two rechargeable batteries are included for carrying a spare.
- Rated for 10,000 PSI and a 5 oz/min flow rate.
- 40-inch hose, LED light, and shoulder strap suit mobile equipment maintenance.
Cons:- Weight is listed as 5.6 lb in the description and 6.16 lb in the specifications.
- Battery capacity and runtime are not specified.
- Its 40-inch hose is shorter than the DEWALT kit’s 42-inch hose.
Best for: Farm and fleet operators who grease many fittings in a work session and want a lock-on trigger plus a spare battery in the kit.
Not ideal for: Buyers who need a clearly stated tool weight or battery capacity, or who want the longer hose and documented battery details listed for the DEWALT 20V MAX kit.
- Maximum pressure:10,000 PSI
- Flow rate:5 oz/min
- Grease capacity:14 oz
- Hose length:40 inches
- Batteries:Two rechargeable lithium-ion batteries
- Weight:5.6 lb in description; 6.16 lb in specifications
- Dimensions:16.5 × 8.3 × 3.1 inches
- Features:Lock-on trigger, LED light, shoulder strap
Our verdict“Choose the TaskStar if a lock-on trigger and two included batteries matter more than precise weight and battery-capacity information.”
Alloyman 2-in-1 Cordless Grease Gun Kit, 12,000 PSI, with Two 4.0 Ah Batteries
The Alloyman earns its place for users who want to change how they hold the gun as access shifts: pistol and straight modes offer more flexibility around crowded machinery than a fixed-grip design such as the DEWALT 20V MAX kit. It also pairs 12,000 PSI output with a stated 5.3 oz/min flow rate, and its two 4.0Ah batteries make the kit more ready for extended work than options whose battery capacity is unspecified. The bulk or cartridge loading choice adds practical flexibility for shops that use both supply formats. The main compromise is substantial: at a listed 12.78 lb, it is heavier than the TaskStar, and the high output does not make it an easy pick for frequent overhead work. Its IP54 protection is described as splash- and dust-resistant, not waterproof.
Pros:- Switches between pistol and straight grip positions for different access angles.
- Includes two 4.0Ah batteries.
- Supports bulk grease loading and 14 oz cartridges.
- Provides a 39.4-inch flexible hose, LED light, and stated 12,000 PSI maximum pressure.
Cons:- Listed weight of 12.78 lb makes prolonged or overhead use more demanding.
- IP54 protection is not described as waterproof.
- Its hose is slightly shorter than the DEWALT 20V MAX kit’s 42-inch hose.
Best for: Mechanics and equipment owners who alternate between tight-access fittings and open work areas, and want two high-capacity batteries included.
Not ideal for: Buyers who frequently grease overhead or carry the tool for long stretches; its listed 12.78 lb weight is a significant burden compared with the TaskStar.
- Maximum pressure:12,000 PSI
- Flow rate:5.3 oz/min
- Grease capacity:600 cc (20 oz) bulk capacity; 14 oz cartridges, 53 mm diameter
- Loading options:Bulk grease or cartridges
- Batteries:Two 4.0Ah batteries
- Hose length:39.4 inches
- Weight:12.78 lb
- Protection:IP54 splash- and dust-resistant
Our verdict“Pick the Alloyman when two grip modes and included 4.0Ah batteries outweigh its heavy carry weight.”
DEWALT 20V MAX Cordless Grease Gun Kit with 4.0Ah Battery and Charger
This DEWALT kit is a strong fit for buyers who want a named 20V platform and the essentials in one package: a 4.0Ah battery, fast charger, shoulder strap, and kit box are included. Its variable-speed trigger gives the operator more control over grease delivery than the TaskStar’s lock-on trigger, which favors sustained flow instead. The 42-inch hose is also the longest among these five products, helping reach awkward fittings without moving the tool as often. Output is rated at 10,000 PSI and up to 5 oz/min, rather than the higher stated pressure and flow of the Alloyman or ELECDIYER. The cost of this ready-to-work setup is bulk: its 14.8 lb listed weight makes it less appealing for extended overhead greasing, and battery life varies with use.
Pros:- Includes a 4.0Ah battery, fast charger, shoulder strap, and kit box.
- Variable-speed trigger helps control grease delivery.
- 42-inch flexible hose and LED light aid work on hard-to-reach fittings.
- Backed by a listed 3-year limited warranty.
Cons:- Listed item weight of 14.8 lb may make prolonged or overhead work tiring.
- Battery life depends on application; the provided data lists up to 16 cartridges per charge.
- Its 10,000 PSI rating is below the Alloyman’s 12,000 PSI and ELECDIYER’s 16,000 PSI figures.
Best for: DEWALT 20V users who want a grease gun kit with battery, fast charger, storage case, and a long hose included.
Not ideal for: Buyers prioritizing low carry weight or higher stated pressure and flow; the Alloyman and ELECDIYER list higher output figures.
- Voltage:20V
- Battery:One 4.0Ah lithium-ion battery included
- Maximum pressure:10,000 PSI
- Flow rate:Up to 5 oz/min
- Hose length:42 inches
- Item weight:14.8 lb
- Included components:Battery, fast charger, shoulder strap, kit box
- Warranty:3-year limited warranty
Our verdict“Choose this DEWALT kit if a complete 20V package and controlled flow matter more than lower weight or higher output ratings.”
DNA MOTORING Cordless Lithium Grease Gun Kit
The DNA MOTORING kit is the simplest choice here for buyers whose main needs are reaching remote fittings and seeing them clearly: its 41.54-inch flexible hose and LED light address those jobs directly. It includes a 21V battery, charger, and carry case, so it arrives as a portable kit rather than a bare tool. That package is more complete than the ELECDIYER, which does not state that a battery is included, but DNA MOTORING provides no pressure, flow-rate, or battery-capacity figures to help judge work speed and runtime. By comparison, the DEWALT kit publishes output figures and a 4.0Ah battery specification, making it easier to match to demanding service work. At 10.8 lb, this model is also no lightweight option for repeated overhead use.
Pros:- 41.54-inch flexible hose reaches fittings beyond the tool’s immediate position.
- LED light supports work in dim areas.
- Battery, charger, and carry case are included.
- 21V lithium battery power source is specified.
Cons:- Maximum pressure and flow rate are not provided.
- Battery capacity and runtime are unspecified.
- Listed 10.8 lb weight may be tiring during extended or overhead use.
Best for: Occasional equipment owners who need a battery, charger, case, long hose, and LED for routine greasing in dim or awkward locations.
Not ideal for: Fleet and shop buyers who need documented pressure, flow rate, or battery runtime to plan frequent, demanding work.
- Power source:21V lithium battery
- Hose length:41.54 inches
- Item weight:10.8 lb
- Lighting:LED
- Included accessories:Battery, charger, carry case
- Brand:DNA MOTORING
- Model:TOOLS-00660
Our verdict“Choose DNA MOTORING for a portable kit focused on reach and visibility, but skip it if verified output and runtime figures are needed.”
ELECDIYER 16,000 PSI Cordless Grease Gun for DeWalt 20V Batteries
For buyers already invested in DeWalt 20V MAX batteries, the ELECDIYER pairs platform compatibility with the highest stated output in this group: 16,000 PSI and 8 oz/min. That gives it a clear output advantage over the DEWALT-branded kit’s 10,000 PSI and up to 5 oz/min figures, while avoiding the need for a separate battery platform if a compatible battery is already on hand. Its 59-inch hose also out-reaches the other products here, and the rotating handle shifts between pistol and inline positions to suit different access angles. The catch is that a battery is not stated as included, unlike the DEWALT kit. At 8.78 lb it is lighter than the DEWALT and Alloyman listings, but compatibility wording beyond DeWalt 20V MAX is limited.
Pros:- Highest stated output in this group at 16,000 PSI and 8 oz/min.
- 59-inch hose offers more reach than the other listed models.
- Rotating handle supports pistol-grip and inline-grip positions.
- Accepts bulk grease or standard 14 oz cartridges and includes onboard coupler storage.
Cons:- Battery is not stated as included.
- Compatibility beyond DeWalt 20V MAX is described only for most compatible platforms.
- Its output figures do not make it a complete kit for buyers who lack a compatible battery.
Best for: DeWalt 20V MAX battery owners who want a long hose, flexible grip positions, and the highest stated pressure and flow in this group.
Not ideal for: Buyers without a compatible DeWalt battery who expect a ready-to-use kit, or those seeking clearly documented support for other battery platforms.
- Working pressure:16,000 PSI
- Flow rate:8 oz/min
- Battery compatibility:DeWalt 20V MAX lithium batteries
- Hose length:59 inches
- Weight:8.78 lb
- Loading options:Bulk grease or standard 14 oz cartridges
- Grease grades:NLGI grades 0–3
- Handle:Rotates up to 90° between pistol-grip and inline-grip positions
- Barrel material:Stainless steel
Our verdict“Choose the ELECDIYER if you own a compatible DeWalt 20V MAX battery and value maximum stated output and hose reach over a battery-included kit.”
DEWALT 20V MAX Cordless Grease Gun, 42-Inch Hose, 10,000 PSI (DCGG571B)
The DEWALT DCGG571B suits maintenance work where access and controlled dispensing matter more than the highest pressure rating. Its 42-inch hose is longer than the Bluebow’s 39.4-inch hose, giving more room to reach awkward fittings while keeping the tool body away from nearby machinery. The variable-speed trigger helps meter grease, and the stated output of up to 5 oz/min supports faster routine servicing. Its 10,000 PSI maximum is below the 12,000 PSI ratings listed for Bluebow and Seesii, so those may be a better fit when maximum pressure is the priority. This is a bare tool listing: a battery is not listed as included, which changes the kit value for buyers without compatible power. The listed 120V spec also conflicts with the 20V MAX name, so verify the power details before buying.
Pros:- 42-inch flexible hose reaches difficult fittings
- Variable-speed trigger supports more controlled dispensing
- Up to 5 oz/min output helps speed routine lubrication
- Integrated foot and LED light add practical support during service work
Cons:- Battery is not listed among the included components
- 10,000 PSI maximum is lower than the 12,000 PSI ratings of the Bluebow and Seesii
- The listed 120V voltage conflicts with the 20V MAX product name
Best for: DEWALT 20V MAX tool owners who need a long hose and variable grease flow for routine fleet, farm, or equipment maintenance.
Not ideal for: Buyers who need a complete ready-to-work kit, want the highest listed pressure, or cannot confirm compatibility because the voltage details conflict.
- Model:DCGG571B
- Power source:Battery powered
- Maximum pressure:10,000 PSI
- Pump output:Up to 5 oz/min
- Hose length:42 inches
- Capacity:14 oz
- Item weight:8 pounds
- Features:Variable-speed trigger, LED light, integrated foot, air-bleeder valve

Our verdict“Choose this DEWALT when long reach and trigger control matter more than a battery-included kit or the lineup’s highest pressure rating.”
Bluebow Cordless Electric Grease Gun Kit, 12,000 PSI, 5.3 oz/min, with Two 4,000 mAh Batteries
The Bluebow is the clearest choice here for buyers who want the batteries included from the outset. It comes with two 4,000 mAh batteries, a case, and an air bleeder valve, so it arrives better equipped for mobile maintenance than the bare-tool DEWALT DCGG571B. Its stated 12,000 PSI pressure and 5.3 oz/min flow also exceed the DEWALT’s listed pressure and output, although the Seesii offers the same stated pressure and flow with a longer 48-inch hose. Bluebow’s 39.4-inch hose should still reach many fittings, but it gives less reach than either rival. The main tradeoff is heft: at 11.77 pounds, it is the heaviest option in this group, and no battery runtime is specified. I’d favor it for work sessions where included power and the case matter more than carrying comfort.
Pros:- Includes two 4,000 mAh lithium batteries
- 12,000 PSI maximum pressure and 5.3 oz/min flow rate
- Carrying case supports transport and storage
- Air bleeder valve helps purge air after refilling
Cons:- 11.77-pound weight makes extended carrying more demanding
- 39.4-inch hose is shorter than the DEWALT’s 42-inch and Seesii’s 48-inch hoses
- Battery runtime is not specified
Best for: Farm and equipment owners who want a cordless grease gun kit with two batteries and a carrying case included.
Not ideal for: Technicians who frequently carry tools around a jobsite, need the longest hose, or require stated battery-runtime information for planning long shifts.
- Model:HYQ-MS-01
- Manufacturer part number:GG-005
- Pressure:12,000 PSI
- Flow rate:5.3 oz/min
- Batteries:Two 4,000 mAh lithium batteries
- Hose length:39.4 inches
- Weight:11.77 pounds
- Included accessory:Carrying case
Our verdict“Pick the Bluebow if included batteries and a case are your priority and its heavier body is acceptable for your maintenance routine.”
Seesii 2-in-1 Cordless Electric Grease Gun, 12,000 PSI, with Two Batteries and 48-Inch Hose
The Seesii earns its place for buyers who need extra hose reach and a choice of loading methods. Its 48-inch hose is the longest among these three, while its 2-in-1 design accepts bulk grease or standard 14 oz cartridges—useful for shops that refill from bulk containers but still want cartridge convenience for some jobs. Like the Bluebow, it lists 12,000 PSI and 5.3 oz/min; unlike that heavier model, Seesii lists a 6.6-pound tool weight. Two 2.0Ah batteries, an LED light, and a case round out the kit. The battery capacity is lower than Bluebow’s stated 4,000 mAh batteries, and runtime isn’t established by the supplied specifications, so I wouldn’t choose it on claimed all-day endurance. Its appeal is reach and loading versatility, not proven runtime.
Pros:- 48-inch flexible hose provides the longest reach of these three options
- Supports bulk grease and standard 14 oz cartridges
- Includes two 2.0Ah rechargeable batteries
- LED light and carrying case support field maintenance
Cons:- Two 2.0Ah batteries have lower stated capacity than Bluebow’s two 4,000 mAh batteries
- Runtime is not established by the supplied specifications
- At 6.6 pounds, it is heavier than a lightweight hand-operated alternative
Best for: Mechanics and equipment owners who service hard-to-reach fittings and switch between bulk grease and standard cartridges.
Not ideal for: Buyers who prioritize larger stated battery capacity or documented runtime over hose length and flexible grease loading.
- Model:SE-GR01 Ultra
- Working pressure:Up to 12,000 PSI
- Flow rate:5.3 oz/min
- Batteries:Two 2.0Ah rechargeable batteries
- Hose length:48 inches
- Grease capacity:400 cc
- Cartridge compatibility:Standard 14 oz cartridges
- Grease grades:NLGI #0, #1, and #2
- Item weight:6.6 pounds
Our verdict“Choose the Seesii for long-reach jobs and flexible grease loading, but look elsewhere if battery capacity documentation is your main concern.”
How We Picked
I compared these 13 kits on the details that shape day-to-day lubrication: stated pressure and output where provided, battery inclusion and compatibility, grip and trigger controls, hose length, couplers, and whether the package is ready to use or tool-only. I also treated maintenance and handling as buying factors: a grease gun needs a reliable way to load and prime, a hose that reaches fittings without awkward positioning, and a setup that makes sense for the user’s work volume.
The ranking favors useful balance over a single headline specification. The DEWALT kit leads for its named battery platform and included battery and charger; flexible-grip models and two-battery packages earn attention for specific access or runtime needs. Tool-only models, less-detailed packages, and picks whose strongest claim is a pressure figure rank lower for buyers who want an easy, well-rounded kit. I do not treat stated PSI alone as proof of better real-world results, and buyers should confirm fit and included components before purchase.

Factors to Consider When Choosing Battery Powered Grease Gun Kit
I would choose a grease gun by starting with the equipment and service routine, then checking what the kit actually supplies. The questions below help avoid paying for power or accessories that do not solve your main problem.
Match Battery Compatibility to Your Existing Tools
Battery-platform compatibility can change the real cost and convenience of a kit more than its headline pressure. A tool-only model built around DeWalt 20V batteries may be a sensible fit if you already own compatible packs, but it is a poor shortcut if you still need to source batteries and a charger. Check the exact battery platform and fit rather than assuming that a similar voltage label means interchangeable batteries. Also think about whether the grease gun will compete with other tools for the same batteries during a workday. If you have no existing platform, an included battery and charger make the first purchase simpler, though a two-battery package can reduce interruptions on longer jobs.
Choose Pressure and Output for the Fittings You Service
Pressure ratings are useful for comparing stated capability, but they do not tell the whole story of how a grease gun will behave on your equipment. A 16,000 PSI claim may sound appealing, yet many buyers benefit more from clear trigger control and an appropriate flow rate than from pursuing the highest number. Check the equipment maker’s lubrication instructions and avoid treating maximum pressure as a target for every fitting. Output figures, when provided, can help estimate how quickly a job may move, but grease type, temperature, and fitting condition also affect flow. If your work includes varied equipment, prioritize controllable delivery and a dependable way to stop pumping.
Treat Hose Reach as a Handling Decision
A longer hose can reach recessed or awkward fittings while the tool stays in a more comfortable position, but extra length can also be harder to manage in a crowded shop or storage compartment. Think through where fittings sit on your machinery and whether you need to hold the gun with one hand while guiding the coupler with the other. A shorter hose may feel tidier for accessible fittings, while a 42- or 48-inch option can reduce repositioning around large equipment. Do not choose by length alone: coupler access, hose flexibility, and how securely the connection stays on a fitting matter too. Leave enough reach for your usual job without buying more hose than you can conveniently control.
Decide Whether Grip Flexibility Is Worth the Extra Complexity
Pistol and in-line grips address different working positions rather than making a kit universally better. A pistol grip may be easier to hold when the fitting is visible and reachable, while an in-line arrangement can help in tighter spaces or when you want to change how the tool is supported. A 2-in-1 design makes sense for varied jobs, but it may add setup steps and does not remove the need to check clearance around the fitting. If your lubrication points are consistent, a simpler handle may be easier to manage and store. Before buying, consider whether you will actually switch configurations often enough to value that flexibility.
Check What ‘Kit’ Means Before You Buy
Product titles use the word kit in different ways, so inspect the included components rather than assuming every package is ready for work. Verify whether the box includes a battery, charger, hose, couplers, and any loading accessories you need for your chosen grease supply. A bare tool can be a better fit for someone invested in a compatible battery platform, while a complete bundle can reduce setup friction for a first-time cordless-tool buyer. Compare the included accessories with the fittings you service; spare couplers are of little use if they do not suit your connections. This check can prevent a tool purchase from turning into a second round of accessory shopping.
Plan for Loading, Priming, and Ongoing Handling
Loading and priming affect how quickly a grease gun is ready and how cleanly it can be maintained. Before choosing, check the manufacturer’s instructions for cartridge loading, bulk filling, air purging, and clearing blockages; a powerful motor cannot compensate for a poor loading routine. Think about where you will store the gun and its hose, especially if the tool travels between sites or rides in a service vehicle. A lock-on trigger may help during repeated applications, but it also makes safe handling and deliberate shutoff more important. For occasional home or equipment maintenance, straightforward controls may matter more than extra modes, while frequent users may value features that reduce fatigue and downtime.
Frequently Asked Questions
Should I buy a tool-only grease gun or a kit with batteries and a charger?
A tool-only option usually makes the most sense when you already own batteries from the exact compatible platform and can use them without disrupting other work. If you need to buy a battery and charger separately, compare the complete setup rather than judging the tool alone. An all-in-one kit is simpler for a first cordless grease gun and reduces uncertainty about what is needed to start. Two-battery bundles can be useful for longer service sessions, though they add gear to store and carry. Confirm the included battery capacity and charger details before choosing.
Is a 16,000 PSI grease gun automatically better than a 10,000 or 12,000 PSI model?
No: a higher stated maximum does not automatically make a grease gun the better match for your equipment or workflow. Check the machine manufacturer’s lubrication requirements, then compare control, output information, hose reach, and battery setup alongside pressure. Maximum pressure is a capability figure, not a recommendation to apply that force to every fitting. If a fitting is blocked or damaged, more pressure may not solve the underlying issue. Choose the model whose stated capability and handling fit the jobs you actually perform.
When is a two-battery kit worth choosing?
A two-battery kit is most useful when you lubricate many machines in one session, work away from a charger, or want a charged spare available while the other pack is in use. For occasional maintenance with short sessions, one battery may be enough and can mean less equipment to manage. Battery capacity also matters: two packs do not tell you how long the tool will run unless you know their capacity and the demands of your work. Consider whether you already share batteries with other tools on the same platform. The best choice depends on how often you work and how costly an interruption would be.
Do I need a 2-in-1 grip, or is a standard grip enough?
A 2-in-1 grip is useful when service points vary in angle or access and you want to change how you hold the tool. If your fittings are mostly open and easy to reach, a standard grip may be less complicated and easier to store. Think about the space around your equipment as well as the fitting itself; a different grip cannot help if the hose or coupler still cannot reach. Frequent changes between work areas make flexibility more valuable than a single, repeatable service task. Pick the design based on your actual access problems, not the number of modes alone.
How much hose reach should I prioritize for farm or vehicle maintenance?
Start by identifying the hardest-to-reach fittings on the equipment you service and estimate how far the tool needs to stay from them for comfortable handling. A longer hose can help around large machinery and confined locations, but it can be more cumbersome to route and store. A 42- or 48-inch hose may suit awkward access better than a shorter one, while accessible vehicle fittings may not need the extra length. Check that the hose and coupler can move into position without sharp bends or pulling on the fitting. If your jobs vary, reach and manageable handling matter more than choosing the longest hose available.
Conclusion
For the broadest mix of readiness and familiar battery-platform support, I would choose the DEWALT 20V MAX Cordless Grease Gun Kit as best overall, particularly for buyers who want a battery and charger included. For buyers who already own compatible DeWalt batteries, the compatible 20V bare-tool models can be the better-value route, provided their package details meet the job’s needs. Beginners should favor a complete kit with the battery, charger, hose, and couplers they need rather than starting with a tool-only purchase. For a premium-style feature choice, the ELECDIYER 16,000 PSI model suits buyers specifically seeking a higher stated pressure and DeWalt 20V compatibility, while those working around awkward fittings should look at a 2-in-1 grip or the 48-inch-hose Seesii. The right choice is the kit that fits your battery supply, equipment access, and work volume—not simply the one with the largest PSI number.
