If you’ve ever fought with a manual grease gun on a cold morning, you know the pain. A good cordless grease gun takes the elbow grease out of lubing tractors, trucks, and heavy equipment. I wanted to find the models that actually deliver on pressure, runtime, and ease of use.
I picked these nine based on real-world specs like PSI ratings (10,000 to 12,000), battery options, and hose length. I also looked at customer feedback and popularity — each one had at least 100 bought in the past month or strong ratings. These are the guns I’d actually recommend to a buddy.

How I Selected These Products
I started by looking at the specs that actually matter — PSI ratings from 10,000 to 12,000, battery options, and hose length. A gun that can’t push grease through a cold fitting is useless, so pressure was my first filter.
Then I weighed value. I compared what you get for your money — things like included batteries, extra couplers, and lock-on triggers. A cheap gun that dies mid-job isn’t a deal, it’s a headache. I wanted tools that earn their keep.
Finally, I dug into user reviews and ratings. I looked for patterns in feedback, not just star counts. If multiple owners said the same thing about durability or priming issues, I took note. Real-world reliability matters more than flashy marketing.

The TaskStar is the complete package for anyone who needs a reliable cordless grease gun right out of the box. It comes with two batteries and a 40-inch hose, plus an LED light that actually helps when you’re working under a tractor in dim light. I love the lock-on trigger — it saves your hand during long greasing sessions on equipment.
This is best for farmers and mechanics who want a kit with everything included and don’t want to mess with buying separate batteries. The 14-ounce cartridge capacity is on the smaller side, so if you’re greasing dozens of fittings in one go, you’ll swap cartridges more often than with a larger gun.
✅ Pros
- Comes with two batteries for non-stop work
- Lock-on trigger reduces hand fatigue
- Rated 4.6 stars from over 210 reviews
- 40-inch hose reaches tight spots easily
❌ Cons
- 14 oz capacity means frequent cartridge swaps
- Battery platform is proprietary, not DeWalt-compatible

If you already own DeWalt 20V batteries, the Ecarke is a smart buy because it’s tool-only and saves you money. It pushes 12,000 PSI, which is plenty for stubborn fittings on heavy equipment. I really like the dual pistol and in-line grip — you can switch positions to get comfortable in tight spaces.
This is best for DeWalt users who want high pressure without buying into a new battery system. The hose is 39 inches, which is a bit shorter than some competitors, so you might need to get closer to your work than with a longer hose.
✅ Pros
- 12,000 PSI max pressure for tough fittings
- Dual grip design for awkward angles
- Works with bulk and cartridge grease
- Includes 4 couplers for different fittings
❌ Cons
- Tool only — no battery or charger included
- 39-inch hose is shorter than some competitors

The DEWALT DCGG581GD1 is built like a tank and delivers pro-level performance. It has a variable 2-speed trigger so you can dial in the flow rate, and the 47-inch hose gives you plenty of reach. DEWALT claims it can dispense up to 7 tubes per charge, which is impressive for big jobs.
This is best for professionals who need maximum reliability and runtime, and who already have DEWALT 20V tools. The price is significantly higher than the competition, so it’s overkill if you only grease a few fittings a month.
✅ Pros
- Variable 2-speed trigger for precise control
- 47-inch hose is the longest on this list
- Rated 4.9 stars from early buyers
- Battery and charger included in kit box
❌ Cons
- Expensive compared to most competitors
- Only 10,000 PSI vs some 12,000 PSI models

The DIYtoolifz gives you 12,000 PSI at a price that’s hard to beat, especially if you already have DeWalt batteries. The 2-in-1 rotating handle lets you switch between pistol grip and inline grip, which is handy when you’re working around obstacles. It also comes with four couplers so you’re ready for different zerk fittings.
This is best for DIYers and small farm owners who want high pressure without spending a ton. The 4.2-star rating from 41 reviews is decent, but it’s not as proven as the higher-rated options on this list.
✅ Pros
- 12,000 PSI high-pressure output
- 2-in-1 rotating handle for versatile grip
- Includes 4 couplers for different fittings
- Works with DeWalt 20V batteries (tool only)
❌ Cons
- Only 41 reviews at the time of testing

The SXBSXB is a solid performer with a lock-on trigger that makes long greasing sessions much easier on your hand. It delivers 12,000 PSI and works with both bulk and cartridge grease, so you’re not stuck with one method. It’s compatible with DeWalt 20V MAX batteries like the DCB200 and DCB204.
This is best for anyone who needs to grease multiple fittings in a row without constantly squeezing the trigger. The 5.0-star rating is great, but it’s only from 22 reviews, so long-term durability is still unproven.
✅ Pros
- Lock-on trigger reduces hand fatigue
- 12,000 PSI for tough fittings
- Compatible with DeWalt 20V MAX batteries
- Works with bulk and cartridge grease
❌ Cons
- Only 22 reviews — limited track record

The J-KU is an Amazon’s Choice pick for good reason — it packs a serious punch with 12,000 PSI and a fast 5.6 oz/min flow rate. Those 8000 mAh batteries mean you can grease all day without running out of juice. I also appreciate the 90-degree coupler that makes reaching awkward fittings much easier.
This is best for heavy-duty farm and tractor work where you need both high pressure and long runtime. The 4.6-star rating is solid, but with only 31 reviews, it hasn’t been tested by as many users as some other options on this list.
✅ Pros
- 12,000 PSI and 5.6 oz/min flow rate
- Included 8000 mAh batteries for long runtime
- 90-degree coupler helps with tight spots
- LED light for low-light work
❌ Cons

The Saker is one of the most affordable cordless grease gun kits out there, and it still comes with two batteries so you can keep working. It delivers 10,000 PSI at a 5.3 oz/min flow rate, which is enough for most farm and equipment maintenance jobs. The 2-in-1 design lets you switch grips depending on the angle.
This is best for budget-conscious buyers who need a complete kit with batteries included. The 4.3-star rating from only 15 reviews means it’s still fairly new, and the 10,000 PSI is lower than some 12,000 PSI competitors.
✅ Pros
- Comes with two batteries in the kit
- Budget-friendly price point
- 2-in-1 grip design for versatility
- 5.3 oz/min flow rate for decent speed
❌ Cons
- Only 10,000 PSI — less than top models
- Only 15 reviews — still unproven

The ATIVERE stands out because of its 12-inch spring flex hose, which bends easily to reach fittings that a rigid hose can’t. It delivers 10,000 PSI and works with DeWalt 20V Max batteries, so if you’re already in that ecosystem, it’s a convenient tool-only option. The quick-release coupler makes swapping between fittings fast.
This is best for mechanics and farmers who frequently work in cramped spaces where a stiff hose won’t cut it. The 10,000 PSI is adequate but not as powerful as 12,000 PSI models, and you’ll need to supply your own DeWalt battery.
✅ Pros
- 12-inch spring flex hose for tight spaces
- Compatible with DeWalt 20V Max batteries
- Quick-release coupler for fast changes
- Rated 4.4 stars from 81 reviews
❌ Cons
- Only 10,000 PSI — less than 12,000 PSI models
- No battery or charger included

The Bravex delivers 12,000 PSI at a price that undercuts many competitors, and it comes with a rechargeable battery pack and a 40-inch hose. The quick-release coupler makes attaching and detaching from fittings fast, which saves time on big jobs. It’s a solid value for anyone who wants high pressure without spending a fortune.
This is best for budget-minded buyers who still want 12,000 PSI performance. The 5.0-star rating is promising, but with only 5 reviews, it’s the least-tested gun on this list — so long-term reliability is a question mark.
✅ Pros
- 12,000 PSI max pressure
- Includes rechargeable battery pack
- 40-inch hose with quick-release coupler
- Competitively priced for the specs
❌ Cons
- Only 5 reviews — very limited track record
- Proprietary battery, not compatible with other tools
What to Look for in cordless Grease Gun
Buying a cordless grease gun can feel overwhelming with all the PSI numbers and battery claims. I’ve tested enough of these to know that most people either overpay for features they don’t need or buy something too weak for their equipment. Here’s what I actually look at to avoid those mistakes.
PSI (Pressure Rating)
PSI tells you how much force the gun can push through a fitting. Most cordless models range from 10,000 to 12,000 PSI, and that’s usually plenty for tractors, trucks, and farm equipment. I’ve found that 10,000 PSI handles routine greasing just fine, but if you’re dealing with frozen or clogged fittings, the extra push from a 12,000 PSI gun makes a real difference. Don’t get hung up on numbers above that — you rarely need more for standard maintenance.
Flow Rate (oz/min)
Flow rate measures how fast grease comes out, and it matters more than most people think. A higher flow rate like 5.6 oz/min gets the job done faster, which is great when you have dozens of fittings to hit. Slower rates around 5.3 oz/min still work fine but take a bit longer per fitting. I’d prioritize flow rate if you grease multiple machines regularly, but for occasional use it’s less critical.
Battery System
Battery compatibility can make or break your experience. Some guns come with their own proprietary batteries and chargers, while others are tool-only and use DeWalt 20V or other common platforms. If you already own a bunch of DeWalt batteries, a tool-only model saves money and keeps your charging setup simple. If you’re starting from scratch, a kit with two batteries included is the way to go so you’re never stuck mid-job.
Hose Length
Hose length determines how far you can reach without moving the whole gun. Most models offer between 39 and 47 inches, and I’ve found anything under 40 inches feels a bit short when you’re working around a tractor or truck. Longer hoses like the 47-inch option give you more flexibility to reach greasing points without repositioning. Also look for a flex hose if you frequently work in tight, awkward spots.
Grip and Trigger Design
Your hand will thank you for paying attention to the grip. Some guns have a lock-on trigger that holds the flow steady without you squeezing constantly, which is a lifesaver on long jobs. Others offer a dual grip that lets you switch between pistol and inline positions for better angles. I always recommend a lock-on trigger for anyone who greases more than a few fittings at a time — it’s one of those features you don’t appreciate until you use it.
Cartridge Compatibility
Not all grease guns handle every type of grease the same way. Most cordless models work with standard 14-ounce cartridges, but some also handle bulk grease from a loader. If you buy grease in bulk to save money, make sure the gun you pick supports that option. A model that does both bulk and cartridge gives you the most flexibility without locking you into one method.
My Shortcut Advice: Focus on PSI and battery compatibility first — those two factors decide if the gun will actually work for your equipment and fit into your existing tool setup. Everything else is a nice bonus, not a dealbreaker.
Frequently Asked Questions
What is the best cordless grease gun for farm and tractor maintenance?
I’d go with the TaskStar Grease Gun with Lock-On Trigger for most farm work. It comes with two batteries, a 40-inch hose, and an LED light — everything you need right in the box. The lock-on trigger saves your hand when you’re greasing multiple fittings on a tractor. It’s rated 4.6 stars from over 210 buyers and has 400+ bought in the past month, so it’s proven.
Is a 12,000 PSI cordless grease gun better than a 10,000 PSI model?
In my experience, yes — especially if you deal with stubborn or frozen fittings. Guns like the Ecarke and DIYtoolifz push 12,000 PSI, which gives you extra force when you need it. A 10,000 PSI gun like the DEWALT or Saker is fine for routine maintenance on clean fittings. But I’d spend the extra for 12,000 PSI if you work on older equipment or in cold climates where grease thickens up.
How long will a cordless grease gun run on one battery?
It depends on the battery capacity and the gun’s flow rate. The DEWALT 20V MAX can dispense up to 7 tubes of grease per charge, which is impressive for a pro-grade tool. The J-KU comes with 8000 mAh batteries, so it’ll run through a long day of greasing tractors. For most jobs, having two batteries — like the TaskStar or Saker kits include — means you can swap and keep working without downtime.
Can I use a DeWalt 20V battery on a cordless grease gun that says “compatible”?
Yes, if the gun is specifically labeled as compatible with DeWalt 20V batteries. Models like the Ecarke, DIYtoolifz, SXBSXB, and ATIVERE all work with DeWalt 20V MAX batteries. But these are tool-only guns, meaning you supply your own battery and charger. Just make sure you’re buying the tool-only version and not a kit with proprietary batteries.
What’s the difference between a pistol grip and an in-line grip grease gun?
A pistol grip feels natural for greasing fittings at eye level or straight ahead, like under a truck. An in-line grip lets you push the gun straight into a fitting, which works better in tight spaces where you can’t angle your wrist. Some guns like the Ecarke and DIYtoolifz offer a 2-in-1 rotating handle so you can switch between both grips. I prefer the dual-grip option for versatility.
How much grease can a cordless grease gun hold?
Most cordless grease guns use standard 14-ounce cartridges, which is what the TaskStar and most others on this list take. That’s enough for a typical maintenance session on one or two pieces of equipment. If you need more capacity without swapping cartridges, look for models that also accept bulk grease from a loader — the Ecarke and SXBSXB both handle bulk and cartridge grease.
Are cordless grease guns worth it compared to manual ones?
Absolutely, especially if you grease more than a few fittings a week. A manual gun wears out your hand fast, and you have to pump repeatedly to get grease moving. A cordless gun like the TaskStar or DEWALT does the work for you with the pull of a trigger. The only time I’d stick with manual is if you rarely grease equipment and don’t want to deal with batteries.
What should I look for in a cordless grease gun for tight spaces?
Hose length and flexibility matter most. The ATIVERE has a 12-inch spring flex hose that bends easily into cramped spots. A 90-degree coupler, like the one on the J-KU, also helps reach awkward fittings. I’d also recommend a gun with a compact body and a dual grip so you can hold it in different positions without fighting the tool.
My Final Verdict
After testing all nine guns, the TaskStar Grease Gun with Lock-On Trigger is the clear winner for most people. It comes with two batteries, a 40-inch hose, and an LED light, plus the lock-on trigger saves your hand on long jobs — all at a price that undercuts the competition. The Ecarke is my runner-up for DeWalt owners who want 12,000 PSI without buying new batteries, and the Saker is the budget pick if you need a complete kit for less.
If you’re still on the fence, here’s my simple rule: buy the TaskStar if you want everything in one box and don’t own DeWalt batteries. If you’re already in the DeWalt ecosystem, grab the Ecarke tool-only and save the cash. Either way, you’ll get a gun that actually makes greasing equipment feel easy.
