Best 16000PSI Cordless Grease Gun for DeWalt 20V
If you’re tired of wrestling with manual grease guns that leave your wrists sore and your knuckles bruised, switching to power is a smart move. The 16000PSI Cordless Grease Gun Compatible with DeWalt 20V Batteries offers serious pressure without the cord drag or the heavy battery pack of larger tools. It’s designed for mechanics, farmers, and DIYers who already own DeWalt batteries and want efficiency.
Our editorial team analyzed hundreds of verified buyer reviews and manufacturer specifications to see if this tool delivers on its promise. We found it excels in tight spaces where hose reach matters more than raw speed. If you need consistent lubrication for equipment maintenance, this could be your new go-to.
Let’s dive into the details.
What it is
This tool is a battery-powered lubrication device engineered to deliver up to 16,000 PSI (Pounds per Square Inch). That level of pressure ensures grease reaches deep bearings even when resistance is high. Unlike traditional manual guns that require significant hand strength, this unit uses an electric motor driven by a lithium-ion cell.
It specifically targets users within the DeWalt ecosystem, allowing you to swap batteries between your drill, impact driver, and this gun. Competitors like Milwaukee and Makita offer similar platforms, but this model focuses on affordability and compatibility rather than proprietary lock-in. It bridges the gap between cheap handheld pumps and expensive shop-mounted units.
Setup & first impressions
Getting started is straightforward because there are no hoses to bleed or compressors to prime. Verified buyers frequently note that the assembly takes less than five minutes. You simply load a standard grease cartridge, attach the coupler, and insert your battery.
The ergonomic handle fits comfortably in most adult hands, reducing fatigue during extended use.
Out of the box, the build quality feels solid despite being plastic-heavy. Users report that the trigger mechanism has a crisp response, avoiding the sluggishness common in cheaper alternatives. The LED light integrated near the nozzle is a standout feature for working under dashboards or inside wheel wells.
This attention to detail suggests the manufacturers considered real-world visibility issues.

Daily-use experience
Performance
The headline number here is 16,000 PSI. In practical terms, this means the gun can force thick NLGI Grade 2 grease through stubborn fittings without stalling. Aggregate user reviews highlight that it handles winter-viscosity greases better than manual counterparts.
You won’t struggle to push lubricant into cold bearings early in the morning.
Speed is adequate for individual fittings. It doesn’t spray instantly like some pneumatic guns, but it maintains steady output. For those maintaining fleet vehicles, this consistency prevents over-greasing which can blow out seals.
Proper lubrication intervals extend component life significantly, much like how checking your engine oil levels regularly protects internal parts.
Comfort & ergonomics
Manual grease guns often cause repetitive strain injuries. This cordless model eliminates that risk entirely. The balanced weight distribution keeps the center of gravity close to the hand, reducing wrist torque.
Users with arthritis or limited grip strength report being able to complete full-service routines without pain.
The pistol-grip design allows for one-handed operation once the coupling is locked. This frees up your other hand to hold flashlights or stabilize equipment. Compared to stick-style guns, this form factor is vastly superior for overhead applications like servicing suspension components on trucks.
Battery / longevity
Since it uses DeWalt 20V cells, runtime depends on your battery amp-hour rating. A standard 2.0Ah battery typically lasts for several full cartridges before needing a recharge. Industry data confirms that Lithium-ion chemistry retains charge well, so leaving it plugged in rarely causes degradation.
For heavy users, carrying two spare batteries ensures uninterrupted workflow. The fuel gauge indicator helps you monitor remaining capacity at a glance. This transparency avoids mid-job failures, a critical advantage over older NiCd technologies used in legacy tools.
Build quality
The housing uses reinforced polymer that resists drops and impacts common in garages. Metal gears drive the piston, ensuring durability against high back-pressure. Some users noted minor flex in the plastic latch after six months, but functionality remained intact.
Regular cleaning prevents grit buildup, similar to maintaining clean wheels on your vehicle to prevent corrosion.
✓ Pros
- High 16,000 PSI output forces grease into resistant fittings easily
- Compatible with widely available DeWalt 20V battery packs
- Integrated LED illuminates dark undercarriage areas effectively
- Lightweight design reduces operator fatigue during long sessions
- Uses standard cartridges, avoiding messy bulk-loading procedures
✗ Cons
- Battery not included, adding cost if you don’t own DeWalt gear
- Hose connection point can leak if not tightened securely
- Plastic exterior may crack under extreme drop impact
- Slower refill rate compared to bulk-fed industrial machines
Who should buy it
Buy it if you…
You maintain personal vehicles, farm equipment, or construction machinery regularly. If you already invest in DeWalt power tools, this integrates seamlessly into your kit. It’s ideal for homeowners who want professional results without renting compressor time.
The portability makes it perfect for roadside repairs or remote job sites where electricity isn't guaranteed.
Think about how you care for your car’s exterior. Just as you’d use a quality cleaner for your rims to protect finish, proper greasing protects moving parts from rust and wear. This tool simplifies that protective step.
Skip it if you…
You operate a large fleet requiring hundreds of pounds of grease daily. Bulk-loading systems save money and time in those scenarios. Also, skip this if you don’t own any 20V batteries, as buying them separately raises the entry cost significantly.
Pneumatic options remain faster for continuous industrial lines.
Better alternatives
Milwaukee M18 Fuel Greaser offers higher peak pressure but costs more. Lincoln Lubrication Equipment provides robust stationary solutions for shops. However, neither matches the specific value proposition of leveraging existing DeWalt assets.
Frequently Asked Questions (FAQ)
Does it work with old DeWalt batteries?
Yes, it accepts all 20V Max Lithium-Ion batteries regardless of age. Older 1.5Ah packs will run shorter times but still function correctly. Newer 4.0Ah or 6.0Ah cells provide extended endurance for multiple carts.
Ensure contacts are clean for optimal conductivity.
How do I remove air bubbles?
Air locks happen when cartridges aren't seated properly. Remove the cartridge, loosen the bleeder valve, and pump until pure grease emerges. Tighten the valve and reload.
Most users resolve this in under two minutes. Keeping your equipment maintained prevents these interruptions, much like tuning your audio system for clarity.
Is the hose replaceable?
Absolutely. Standard hydraulic threads allow swapping damaged hoses easily. Replacement parts are inexpensive and widely available online.
Inspect connections periodically for leaks, especially after dropping the tool. Durable hoses ensure safety during high-pressure operations.
Can I use synthetic grease?
Yes, the pump mechanisms handle both mineral-based and synthetic formulations. Synthetic greases often perform better in extreme temperatures, aligning with needs for winter-ready automotive fluids. Always check viscosity ratings against manufacturer guidelines for best results.
What happens if the battery dies mid-cart?
The gun stops pumping immediately. Swap in a fresh battery to resume. No grease spills occur due to sealed check valves.
This reliability minimizes waste and mess compared to manual guns that might drip when released suddenly.
Final verdict
We rate this cordless grease gun 4.7 out of 5 stars. It transforms tedious maintenance into a quick, comfortable task. Mechanics and hobbyists alike benefit from reduced physical strain and improved precision.
The ability to utilize existing battery infrastructure makes it a financially savvy choice for many workshops.
Buy it if you prioritize ergonomics and already own DeWalt tools. Skip it only if your volume demands industrial bulk systems. For the vast majority of users, this represents the sweet spot between performance and price.
It empowers you to keep machinery running smoothly without breaking a sweat.
