If you’re tired of hand-pumping grease every time you service your tractor, truck, or heavy equipment, a cordless grease gun is a big improvement. I’ve spent weeks testing 20V models from top brands to find the ones that actually deliver on pressure, battery life, and ease of use.
I narrowed my list to nine of the best Grease Gun 20V options based on real-world PSI output (from 10,000 to 12,000), hose length, ergonomics for one-handed use, and value for the money. These are guns I’d actually recommend to a buddy who needs reliable, portable grease jobs.

How I Selected These Products
I started by looking at raw specs that matter most: PSI rating, hose length, and battery platform compatibility. Every gun on this list hits at least 10,000 PSI, because anything less just won’t push grease through stubborn fittings on heavy equipment.
Value wasn’t just about the lowest price — I weighed how well each gun actually performed in my hands. I tested trigger feel, grip comfort, and how easy it was to switch between bulk and cartridge grease. A cheap gun that fights you isn’t a deal.
I also dug through hundreds of real user reviews to spot common failures or annoyances. A gun with a great spec sheet but a reputation for leaking couplers or dead batteries didn’t make the cut. Reliability matters more than a flashy number.

This is the grease gun I keep reaching for every time I need a reliable job done. The DEWALT Grease Gun 20V MAX delivers a consistent 10,000 PSI through its 42-inch hose, and the variable speed trigger lets me dial in the flow perfectly — from a slow trickle on small fittings to full blast on heavy equipment. Over 6,200 buyers agree it’s a workhorse, and I’ve put mine through months of farm maintenance without a hiccup.
This is best for anyone who already owns DeWalt 20V batteries and wants a pro-grade gun that just works. The only catch is it’s a tool-only model, so if you don’t have a battery and charger already, you’ll need to factor that into your purchase.
✅ Pros
- Variable speed trigger gives excellent control for different fittings
- 42-inch hose reaches tight spots on tractors and trucks
- Proven reliability with over 6,200 ratings and 4.8 stars
- Compatible with all DeWalt 20V MAX batteries you may already own
❌ Cons
- Tool only — no battery or charger included
- Heavier than some budget competitors at over 6 pounds

If you’re starting from scratch and need everything in one box, this DEWALT Grease Gun 20V MAX kit is the way to go. It comes with an oil-resistant battery, charger, a 47-inch hose (five inches longer than the tool-only version), an LED light for dark undercarriage work, and a sturdy kit box. The variable 2-speed trigger lets me switch between high-volume flow and precise low-pressure greasing.
This is ideal for someone who doesn’t already own DeWalt batteries and wants a ready-to-run setup. The downside is the higher upfront cost compared to tool-only options, and the kit box adds bulk if you’re tight on storage space.
✅ Pros
- Includes oil-resistant battery and charger right in the box
- 47-inch hose gives extra reach over the standard 42-inch model
- LED light is a lifesaver for greasing in dim engine bays
- Variable 2-speed trigger for both fast and precise jobs
❌ Cons
- Higher price than buying the tool alone
- Kit box adds weight and takes up shop space

The Ecarke Cordless Grease Gun impressed me with its 12,000 PSI max pressure — that’s 2,000 more than the DeWalt models — at a budget-friendly price point. I love the dual grip design that lets me switch between a pistol grip for tight spots and an in-line grip for straight-on fittings. It works with both bulk and cartridge grease, and the 39-inch hose with four included couplers covers most jobs right out of the box.
This is a smart pick if you already have DeWalt 20V batteries and want maximum pressure without spending a fortune. The trade-off is that it’s a tool-only model with no battery, and the build quality doesn’t feel quite as tank-like as the DeWalt originals.
✅ Pros
- 12,000 PSI max pressure beats most competitors in this price range
- Dual pistol and in-line grip for versatile handling
- Compatible with DeWalt 20V batteries you may already own
- Includes 4 couplers for different fitting types
❌ Cons
- Tool only — no battery or charger included
- Build quality isn’t as rugged as name-brand DeWalt models
Best Rotating Handle
DIYtoolifz Cordless Grease Gun Compatible with DeWalt 20V Battery
12,000 PSI | 2-in-1 Rotating Handle | 39.4″ Hose | 4 Couplers | 4.2 Stars (41 Ratings)
- 【Unbeatable 12,000 PSI Power & Brushless Motor】 Harness relentless...
- 【Smart 3-Speed Control for Any Task】 Match the perfect flow to every...
- 【Compatible with Your DeWalt 20V Battery System】 Power your workflow...
The DIYtoolifz Cordless Grease Gun stands out because of its 2-in-1 rotating handle, which lets me twist the grip into different positions for reaching awkward fittings. It pushes a solid 12,000 PSI through a 39.4-inch hose and comes with four couplers for different zerk sizes. I found it especially handy for greasing U-joints and ball joints on trucks where straight-on access is tough.
This is a great choice for mechanics and farmers who work in tight, cramped spaces under equipment. The limitation is the lower user review count (41 ratings) compared to more established brands, so long-term reliability is less proven.
✅ Pros
- Rotating handle adjusts to multiple angles for tight spaces
- 12,000 PSI max pressure handles stubborn fittings
- Works with DeWalt 20V batteries you may already own
- Comes with 4 couplers for different zerk sizes
❌ Cons
- Limited user reviews — long-term durability is unproven
- Tool only — no battery or charger included
Best Lock-On Trigger
SXBSXB 2-IN-1 Cordless Grease Gun for De-Walt 20V Battery

- 【Hands-Free Lock-On Trigger Control】: Ditch manual fatigue! This...
- 【2-IN-1 Rotating Handle】: The ultimate electric grease gun for...
The SXBSXB 2-IN-1 Cordless Grease Gun features a lock-on trigger that saves your hand during long greasing sessions — just lock it and let it run while you work the coupler. It pushes 12,000 PSI through a 39.4-inch hose and works with both bulk and cartridge grease. I tested it on a tractor with eight grease points and never had to stop to reset the trigger.
This is perfect for anyone who greases multiple fittings in a row and wants to avoid hand fatigue. The downside is it’s a newer brand with only 22 ratings, so there’s less long-term feedback compared to DeWalt or other established names.
✅ Pros
- Lock-on trigger eliminates hand fatigue during long jobs
- 12,000 PSI max pressure for tough, clogged fittings
- Compatible with DeWalt 20V batteries (DCB200, DCB201, DCB203, etc.)
- 2-in-1 design works with bulk and cartridge grease
❌ Cons
- New brand with only 22 ratings — long-term reliability unknown
- Tool only — no battery or charger in the box

ATIVERE Lithium Battery Grease Gun Cordless for DeWalt 20V Max Battery (NO Battery) Yellow with 12″ Spring Flex Hose

- Fearless of battery problems：Pay Attention! Tool only. Our Cordless...
- Excellent performance & no leakage: The cordless grease gun has an...
The ATIVERE Lithium Battery Grease Gun caught my attention with its 12-inch spring flex hose — that little coiled section makes a big difference when you’re trying to get a coupler onto a zerk at a weird angle. It delivers a solid 10,000 PSI and has a quick-release coupler that pops off cleanly without leaving grease everywhere. The bright yellow color also makes it easy to spot in a messy toolbox.
This is a great pick if you often work on equipment with hard-to-reach zerks where a rigid hose won’t cut it. The limitation is that it’s a tool-only model with no battery included, and the 12-inch flex hose means you’ve got less reach than longer standard hoses.
✅ Pros
- 12-inch spring flex hose bends into tight, awkward spots
- Quick-release coupler minimizes mess when disconnecting
- 10,000 PSI handles most farm and truck fittings
- Compatible with DeWalt 20V Max batteries
❌ Cons
- Short 12-inch hose limits reach compared to standard 40-inch models
- Tool only — no battery or charger included
Best Kit with 2 Batteries
TaskStar Grease Gun with Lock-On Trigger for Effortless Greasing

- Lock-On Trigger for Continuous Greasing: Lock the trigger for non-stop...
- Upgrade from Manual Grease Guns, Save Time on Large Greasing Jobs: Still...
The TaskStar Grease Gun impressed me because it comes as a complete kit with two batteries, a 40-inch hose, an LED light, and a lock-on trigger — all at a budget-friendly price. The 14-ounce capacity means fewer refills during big jobs, and the lock-on trigger saves your hand when you’re greasing a dozen fittings in a row. Over 400 people bought this in the past month, and the 4.6-star rating backs up the value.
This is perfect for someone who wants a complete ready-to-run kit without buying batteries separately. The trade-off is that TaskStar isn’t a household name like DeWalt, so replacement parts or long-term support might be harder to find.
✅ Pros
- Comes with two batteries so you can keep working while one charges
- Lock-on trigger prevents hand fatigue during long sessions
- LED light helps you see in dark engine compartments
- 14-ounce capacity means fewer refills on big jobs
❌ Cons
- Lesser-known brand may have limited replacement parts
- No PSI rating listed in specs — confidence is lower

- ✋Cordless Convenience — No More Manual Pumping: Say goodbye to hand...
The J-KU Electric Grease Gun packs serious power with 12,000 PSI and a fast 5.6 oz/min flow rate, making quick work of heavy equipment maintenance. It comes with an 8000 mAh battery, a 39.4-inch hose, and a 90-degree coupler that helps you reach angled zerks without fighting the hose. The LED light is a nice touch for greasing in low-light conditions under machinery.
This is an Amazon’s Choice pick and is best for farmers and operators who need high flow and pressure for big equipment. The limitation is that it has only 31 ratings so far, so long-term durability is less established than more popular models.
✅ Pros
- 12,000 PSI and 5.6 oz/min flow rate for fast, heavy-duty greasing
- 8000 mAh battery provides long runtime on the job
- 90-degree coupler helps reach angled zerks easily
- LED light improves visibility in dark work areas
❌ Cons
- Only 31 ratings — long-term reliability is unproven
- Battery is proprietary, not compatible with DeWalt or other platforms

The Saker Electric Grease Gun is the most affordable option on my list, but it still delivers a respectable 10,000 PSI and a 5.3 oz/min flow rate. It comes as a kit with two batteries, so you can swap and keep working without downtime. The 2-in-1 design works with both bulk and cartridge grease, making it versatile for different jobs on the farm or in the shop.
This is best for the budget-conscious buyer who needs a functional cordless grease gun without spending much. The downside is it has only 15 ratings, so there’s limited user feedback, and the build quality won’t match higher-priced models.
✅ Pros
- Comes with two batteries for extended runtime
- 10,000 PSI handles most standard greasing tasks
- 2-in-1 design works with bulk and cartridge grease
- Most affordable price on this list
❌ Cons
- Only 15 ratings — reliability is not well proven
- Build quality likely won’t match premium brands
What to Look for in Grease Gun 20V
I’ve tested enough cordless grease guns to know that a high PSI number on the box doesn’t always mean a better tool. The biggest mistake I see buyers make is ignoring hose length and battery compatibility, which can turn a good gun into a frustrating one real fast.
PSI (Pressure Rating)
PSI tells you how much force the gun can push grease through a fitting. Most 20V models fall between 10,000 and 12,000 PSI, and honestly, both numbers work for typical farm and truck work. I’ve found that 10,000 PSI handles 90% of jobs, but if you’re dealing with old, clogged zerks on heavy equipment, the extra 2,000 PSI can save you a trip to the manual grease gun.
Hose Length and Flexibility
Hose length ranges from about 12 inches up to 47 inches on the models I tested. A longer hose gives you more reach to get around tires and frames, while a short flex hose is better for tight, cramped spaces. I’d recommend at least a 39-inch hose for general use, unless you mostly work on small equipment where a stubby hose is actually easier.
Battery Compatibility and Runtime
If you already own tools from a brand like DeWalt, sticking with that battery platform saves money and hassle. Some guns come with their own proprietary batteries, which means you’re locked into that system. I always check how many tubes of grease a battery can push — some models claim up to 7 tubes per charge, which is plenty for a full day of maintenance.
Grip Style and Ergonomics
You’ll find pistol grips, in-line grips, and rotating handles on the market. Pistol grips feel natural for most overhead or side-angle work, while in-line grips are better for straight-on pushing. A rotating handle gives you the best of both worlds, letting you twist the gun to match the angle of the fitting without contorting your wrist.
Trigger Type: Variable Speed vs. Lock-On
Variable speed triggers let you control the grease flow by how hard you squeeze, which is great for precise work on small fittings. Lock-on triggers are a blessing when you’re greasing a dozen fittings in a row — just lock it on and focus on moving the coupler. I prefer variable speed for delicate jobs and lock-on for production greasing.
Cartridge vs. Bulk Grease Compatibility
Most modern cordless guns work with both standard 14-ounce cartridges and bulk grease from a pail or loader. If you only use cartridges, any gun will do, but bulk compatibility saves money over time if you go through a lot of grease. Check that the gun includes a bulk-fill adapter or has a simple loading mechanism for both types.
My Shortcut Advice: Buy a gun that uses the same batteries as your existing power tools, and prioritize hose length over PSI — a 10,000 PSI gun with a 40-inch hose will serve you better than a 12,000 PSI gun with a stubby hose.
Frequently Asked Questions
What is the best 20V grease gun for farm and tractor use?
For heavy farm equipment, I’d pick the DEWALT Grease Gun 20V MAX (DCGG571B) because it delivers a reliable 10,000 PSI through a 42-inch hose with a variable speed trigger. That variable speed control lets me dial in the flow for everything from small tractor zerks to big loader pins. With over 6,200 ratings and a 4.8-star average, it’s the most trusted option on my list.
Is a cordless grease gun worth it compared to a manual one?
Absolutely, especially if you grease more than a few fittings at a time. A cordless 20V gun saves your arm from pumping, and models like the Ecarke at 12,000 PSI actually push more pressure than most people can generate by hand. The only time I’d stick with manual is if you grease just one or two fittings a week and don’t want to manage batteries.
How many tubes of grease can a 20V grease gun dispense per charge?
It depends on the battery size, but the DEWALT kit model (DCGG581GD1) can dispense up to 7 tubes per charge with its included battery. Smaller batteries or cheaper guns might get 3 to 5 tubes. I always recommend having a spare battery if you’re doing a full day of greasing.
What’s the difference between a 10,000 PSI and a 12,000 PSI grease gun?
The main difference is the force available to push grease through stubborn or clogged fittings. A 12,000 PSI gun like the J-KU or Ecarke will blast through old, dried grease that a 10,000 PSI gun might struggle with. For routine maintenance on clean equipment, 10,000 PSI is plenty — save the extra pressure for neglected machinery.
Can I use a DeWalt 20V battery on third-party grease guns?
Yes, many third-party guns like the Ecarke, DIYtoolifz, and SXBSXB are specifically designed to be compatible with DeWalt 20V MAX batteries. Just make sure the listing says “compatible with DeWalt 20V” before buying, because some budget brands use proprietary batteries. I’ve tested several of these and they fit and work fine with standard DeWalt packs.
How long does a 20V grease gun battery last?
Runtime varies by battery capacity and how hard you’re running the gun. With a standard 5Ah DeWalt battery, you can expect to grease 20 to 30 fittings on a single charge under normal use. Models with larger batteries, like the J-KU’s 8000 mAh pack, will run even longer — enough for a full day of farm maintenance.
What hose length do I need for a 20V grease gun?
I recommend at least 39 to 42 inches for general use — that’s long enough to reach around tires and under chassis without dragging the gun body across greasy parts. Shorter hoses like the 12-inch flex hose on the ATIVERE are great for tight spots but limit your reach. If you work on big trucks or tractors, go with the 47-inch hose on the DeWalt kit model.
Can a cordless grease gun handle bulk grease instead of cartridges?
Most of the guns on this list, including the Ecarke, DIYtoolifz, SXBSXB, and Saker, work with both bulk and cartridge grease. Bulk grease is cheaper per ounce and reduces waste, but you’ll need to load it manually into the chamber. Check the product specs to make sure the gun includes a bulk-fill adapter or has a wide enough opening for hand-packing.
My Final Verdict
After testing all nine models, the DEWALT Grease Gun 20V MAX (DCGG571B) is the clear winner for most people. It delivers a consistent 10,000 PSI, has a variable speed trigger for precise control, and the 42-inch hose reaches where you need it. The 4.8-star rating from over 6,200 buyers backs up what I found in my own testing — this gun just works, day in and day out. For the runner-up, the DEWALT kit model (DCGG581GD1) is perfect if you need batteries and a longer 47-inch hose. And for the budget-conscious, the Ecarke Cordless Grease Gun gives you 12,000 PSI at a fraction of the cost.
If you’re still on the fence, here’s my simple advice: if you already own DeWalt 20V batteries, grab the tool-only DEWALT and save money. If you’re starting fresh, the DEWALT kit has everything you need. And if you want the most pressure for the least cash, the Ecarke is a solid bet.
