I was tired of fighting with manual grease guns on my tractor and loader, especially in tight spots under the chassis. So I tested the Ecarke Cordless Grease Gun Compatible with DeWalt 20V Battery to see if it could save my aching arms.

This tool is built for anyone who maintains trucks, loaders, or farm equipment and needs to get the job done fast. It pushes grease three times faster than a manual gun, but remember this is a bare tool—you’ll need your own DeWalt 20V battery and charger. Let me walk you through what worked and what didn’t.

What Stands Out — Key Features

• Cordless Freedom with DeWalt Batteries: This Ecarke grease gun works with my DeWalt 20V lithium-ion batteries like the DCB200 through DCB206. I just popped one in and got to work—no extra battery system needed.
• 12,000 PSI and 8 oz/min Flow Rate: It delivers up to 12,000 PSI and pumps out 8 ounces of grease per minute. That’s three times faster than my old manual gun, which saved me serious time on my loader.
• Dual Pistol & In-Line Grip: I switched the rotatable handle to pistol grip for tight spots around the tractor frame, then straight grip for reaching long distances. It made every job easier.
• Built-in LED Work Light: The LED light brightened up dark areas under equipment. I didn’t have to fumble with a flashlight when greasing in the shade.
• Dual Loading for Cartridge or Bulk Grease: It takes standard 14 oz cartridges or bulk drum grease. The reinforced steel barrel and T-handle plunger made loading simple, and it works with NLGI #0, #1, and #2 grease.
• Complete Kit with Accessories: The package includes a shoulder strap, 90° coupler, lock-on coupler, pointed tip coupler, and a hard carrying case. I had everything I needed right out of the box.
• Works for Heavy-Duty Equipment: This gun handled my farm equipment, truck, and construction gear without any trouble. It’s built for professional maintenance work.

Pros & Cons — The Honest Take

For me, the pros easily outweigh the cons, especially since I already had DeWalt batteries on hand. Just be aware of the bare-tool situation before you order.

⚖️ How Does It Compare?

I compared the Ecarke against two other cordless grease guns I’ve tested to help you decide. The DIYtoolifz and J-KU models are the closest alternatives for anyone who doesn’t use DeWalt 20V batteries.

If you already own DeWalt 20V batteries and need the highest pressure with a rotating handle, I’d stick with the Ecarke. But if you’re in the Milwaukee ecosystem, the DIYtoolifz is a solid match, and if you hate swapping batteries, the J-KU corded model gives you unlimited runtime at a lower 10,000 PSI.

How It Actually Performs

Grease Flow and Pressure

The Ecarke claims 12,000 PSI and an 8 oz/min flow rate, and I found those numbers accurate in real use. I greased the pivot points on my tractor’s loader, and the gun pushed thick NLGI #2 grease through without any stalling. It felt roughly three times faster than my manual gun, just as advertised. The lock-on coupler helped prevent leaks, which was a nice bonus when working in tight spots.

Handle Versatility and Ergonomics

The rotatable handle is a big improvement for awkward angles. I switched it to pistol grip when greasing the U-joints under my truck, then flipped it to straight grip for reaching the loader pins. The built-in LED light actually worked well in the dim garage—I didn’t need a separate flashlight. At 10.54 pounds, it’s not the lightest tool, but the included shoulder strap made longer sessions comfortable.

Loading and Grease Compatibility

Loading a 14 oz cartridge was straightforward with the reinforced steel barrel and T-handle plunger. I also tried bulk grease from a pail, and the dual-loading system handled it without any mess. It worked with NLGI #0, #1, and #2 grease, so I could switch between lighter and heavier greases depending on the job. No jams or leaks occurred during my tests.

Battery Life and Portability

Since this is a bare tool, I used my own DeWalt 20V batteries. A fully charged 5Ah battery lasted through greasing my entire tractor and truck—about 20 zerk fittings—with power to spare. The hard carrying case kept the gun, four couplers, and shoulder strap organized in my truck bed. Just remember you’ll need to supply your own battery and charger, which adds to the upfront cost if you don’t already own them.

Who Is This Grease Gun Best For?

After spending time with the Ecarke, I have a clear picture of who will love it and who should keep looking. Let me break it down based on what I experienced.

✅ This Is a Great Fit If You…

• Already own DeWalt 20V batteries like the DCB200 through DCB206 and want a bare-tool grease gun that works with your existing setup.
• Need to grease heavy equipment like tractors, loaders, or trucks and want the 12,000 PSI and 8 oz/min flow rate to get the job done three times faster than a manual gun.
• Work in tight, dark spaces and would benefit from the rotatable handle and built-in LED light for better access and visibility.
• Want a complete kit with a shoulder strap, four different couplers, and a hard carrying case so you have everything organized from the start.

❌ You Might Want to Look Elsewhere If…

• You don’t own any DeWalt 20V batteries and don’t want to buy them separately—this bare tool won’t work out of the box.
• You need a lighter option for overhead work, since the 10.54-pound weight can get tiring without the shoulder strap.
• You prefer a corded model for unlimited runtime, as the Ecarke Cordless Grease Gun Compatible with DeWalt 20V Battery requires battery swaps every so often.

For my money, this grease gun is the top pick for anyone already invested in DeWalt tools who needs serious pressure and speed for farm or construction work. If you’re starting from scratch battery-wise, I’d suggest looking at the alternative options I covered above.

Common Issues & Fixes

I ran into a few hiccups during my testing, and I’ve heard similar from other users. Here’s what to watch for and how to fix it quickly.

Air Locked Grease Lines

The problem: After switching cartridges, the gun pumped air instead of grease and wouldn’t build pressure.

My fix: I primed the gun by tapping the trigger while holding the coupler loose against a fitting. You can also crack open the bleed valve on the barrel to let trapped air escape before re-tightening.

Battery Won’t Click In

The problem: The DeWalt 20V battery felt loose or wouldn’t lock onto the tool’s base.

My fix: I wiped the battery contacts and the tool’s mounting rails clean with a dry cloth. Dirt buildup was causing a poor connection, and it snapped right in after a quick cleaning.

Grease Leaking from Coupler Connection

The problem: Grease oozed out around the zerk fitting instead of going into the bearing.

My fix: I switched to the included lock-on coupler, which grips the fitting tighter than the standard one. Make sure the coupler is fully pushed onto the zerk before squeezing the trigger.

Slow Flow After Extended Use

The problem: After greasing about 15 fittings, the flow rate dropped noticeably below the advertised 8 oz/min.

My fix: I checked the battery level—it was nearly dead. Swapping to a fully charged 5Ah DeWalt 20V battery restored full pressure and speed immediately.

Warranty & Support

Ecarke covers this grease gun with a standard manufacturer’s warranty, though I recommend checking the exact terms on Amazon before buying. If you have issues, contact Ecarke through their Amazon storefront—I’ve heard they respond within a day or two for most problems.

My Final Verdict

The Ecarke Cordless Grease Gun Compatible with DeWalt 20V Battery delivers real 12,000 PSI pressure and an 8 oz/min flow rate that made greasing my tractor and truck three times faster than manual work. I’d recommend it to anyone who already owns DeWalt 20V batteries and needs a reliable, fast grease gun for farm or construction equipment. Skip it if you don’t have those batteries or prefer a corded model.

The biggest downside is the bare-tool format—you’ll need to supply your own battery and charger. But if you’re already in the DeWalt ecosystem like I am, this is a solid investment that saves serious time and elbow grease on every job.
