Best Cordless Grease Guns of 2025

"After years of thinking about it, I finally purchased this grease gun. The price was fantastic, and after using it yesterday, I'm thrilled with its effortless performance. I wholeheartedly recommend this product!"

"I've been using my DeWalt grease gun daily for several months without any issues. It's the best electric grease gun I've owned, outperforming even my former Blue Point. Extremely powerful and compact!"

"As a mechanic for 45 years, I can say this is the strongest grease gun I've ever used. It tackles every fitting without fail, finishing jobs quickly and without the usual frustration. It's worth every penny!"

"I bought this grease gun due to the excessive maintenance at work. It has significantly cut my time for a PM. The long-lasting battery works great with a quick connect fitting, and it's been effective even for clearing jammed grease fittings."

"At 64 years old, I find this grease gun to be a life saver. I've used it to run three cartridges, and the chuck holds nicely. Although the instructions could be better, I've found helpful videos online for priming and installation. I would definitely buy this again."

"This grease gun is perfect for field use when there's no power. It's easy to operate and provides great pressure for tight joints. I truly wish I had gotten one of these years ago!"

"This cordless grease gun is a game-changer! It's powerful, easy to use, and saves me a lot of time. I'm highly satisfied with this tool!"

"I can't believe I waited so long to buy this! It’s so easy to lube my car and truck. A must-have for anyone maintaining their own vehicles!"

"Holy Moly! I have to grease my backhoe and I dreaded using my manual one. But with this bad boy, it literally took four minutes to do each backhoe. The pressure is amazing! No complaints at all!"

"I've been really pleased with my Ryobi grease gun. It's an excellent addition to my tool collection, especially since I already have Ryobi batteries. The greasing process is quick and effortless. It's great that it doesn't drip grease when I'm storing it!"

"I recently switched to this battery-operated grease gun for my projects. It's a game-changer compared to the manual one I used before. Loading grease is simple, and I can get everything done in just a few minutes instead of struggling for half an hour!"

"I had issues with my grease gun after a while. It stopped pouring grease, which was disappointing. I was satisfied initially, but now I'm not so sure about the longevity of the product."

"I was really excited to get this grease gun for my work. Previously, I used a manual grease gun, but I'm thrilled with this electric version. The packaging is impressive, and it even comes with a nice case for storage. Plus, having two batteries is a huge advantage, ensuring I always have one ready to go. The shoulder strap is also a great feature, making it easier to handle during use."

"Let me share my thoughts on this product. I appreciate the overall design, especially the ability to change the orientation. The inclusion of two batteries is a significant plus, along with a decent storage case. The accessories like the shoulder strap and extension tube add value, and the light is helpful for tight spaces. However, I found the charger to be slow and not as robust as I would expect for a tool aimed at professionals. That's why I rated it 4 stars, as it seems better suited for DIYers rather than heavy-duty use."

"I replaced an old manual pump grease gun with this electric model, and it's so much easier to use. I can just set it on the ground and hit the button instead of needing both hands to pump. The battery life is pretty good, and overall, I'm very satisfied with this upgrade."

"I picked this up from the Amazon 2nd chance bin for a bargain. After adding a locking coupler and some grease, I primed it and got to work. It made short work of my job, delivering good pressure. I used it on my JD 430C crawler and it worked great, especially for the price I paid!"

"I got the VEVOR electric grease gun and initially struggled to get it to work. I spent two hours trying to burp it, following all the instructions, but it just wouldn't cooperate. After several emails with Vevor, they told me to reach out to Amazon for a refund. I had hoped for better customer service, but now I'm left wondering if the product is even good at all."

"My grease gun worked perfectly right out of the box. It has solid pressure, but I learned the hard way to keep the air bleed tight or my workspace could get messy. Overall, it’s one of the best purchases I've made recently!"

"This grease gun works great! It saves me so much time, especially with my bad shoulders. It really makes greasing the mowers and tractor much easier."

"I found this grease gun easy to set up and use. I'm planning to switch the grease fitting to a new style that clamps onto the grease zerk, as the current one is a bit tricky to remove."

"I have both manual and air grease guns, but they can be exhausting, especially when greasing my excavator. I decided to try the TaskStar Battery Grease Gun, and I'm glad I did. It works flawlessly! My only complaint is about the case, as it was designed for the hose to stick out, which is why I didn't give it a full five stars."

"This grease gun is heavy compared to my old pneumatic one, but still manageable. I use it on farm equipment and prefer reliable tools. My only issue was the grease coupler; it wouldn’t fit any grease fitting I tried. I switched it out for my aftermarket couplers and now the gun works great. Since I have several Craftsman 20V tools, the battery compatibility and lower price were key factors in my purchase."

"I was fed up with manual grease guns breaking after a season or two. The price and brand didn’t matter; they all failed. I already had the V20 battery system, so I was keen to try this grease gun. It was easy to load and purge the air, which is usually a hassle with manual guns. Once primed, it worked flawlessly. I would definitely recommend it to hobbyists and shade tree mechanics."

"I recently bought a mini excavator and needed a better way to lubricate it. My hand pump wasn’t going to cut it! This grease gun has been a game changer; it makes large tasks quick and easy. I rated it 4 stars because it doesn’t come with a bag, and grease guns can get quite messy. A carrying bag would really help!"

"I chose this grease gun because it came with two batteries and I liked the case design. However, I found that my additional accessories don’t fit in the case, which is a bit disappointing. Other than that, the machine works great and looks nice!"

"After following the instructions, I charged the batteries and primed the grease gun as directed. It performed flawlessly on about 50 grease fittings without any hiccups. I trust Lincoln because my previous model never failed me, and this one is equally impressive!"

"I absolutely love this grease gun! For the price, it’s fantastic. It easily handles even the most stubborn clogged bushings. The counter is super handy and accurate, and I appreciate that it’s auto priming, unlike some competitors. Highly recommend!"

“I've been using this tool in a commercial capacity for months without any issues! It's definitely worth the investment, especially since I received two extra batteries for free. Just a tip, make sure to buy some locking tips for grease certs.”

“I found this product packaged correctly and it works perfectly. While some people complain about needing to remove the hose for storage, I managed to make it work by putting a hole in the side of the case. It handled plugged zerks well, hitting 1300 psi and getting them greased!”

“The convenience of this tool for my tractor, which needs greasing every 10 hours, is fantastic. However, it does leak grease from the tube when I set it down, possibly due to a poor plunger seal. I guess I’ll just have to store it in a pan and wipe it off each time.”
