The DEWALT 20V MAX Cordless Grease Gun Kit delivers professional-grade lubrication with a powerful 10,000 PSI output. It includes a 4.0Ah battery, charger, and a flexible 42-inch hose for hard-to-reach fittings.
Pros
- ✓ Variable speed triggers allow precise grease flow control
- ✓ LED light illuminates dark work areas effectively
- ✓ Long battery life with included 4.0Ah battery
Cons
- ✗ Heavy and bulky for extended overhead use
- ✗ Battery charger can be slow to recharge
My Honest Opinion
This grease gun is a solid performer for heavy-duty tasks, offering reliable power and convenience. While it's a bit heavy, the variable speed and LED light make up for it. I'd recommend it for frequent users needing cordless freedom.
The DEWALT DCGG571M1 excels in performance with its 10,000 PSI max pressure and dual variable speed triggers, making it easy to control grease flow for different applications. The included 42-inch hose provides excellent reach, and the LED light is a thoughtful addition for dimly lit jobs. The 4.0Ah battery lasts through multiple uses, though the charger could be faster.
On the downside, the unit is noticeably heavy, which can cause fatigue during prolonged overhead work. The lack of a built-in grease level indicator means you have to check manually. Overall, it's a robust tool that handles tough jobs well, but consider the weight if you need it for extended periods.

Pros
- ✓ High-pressure output up to 10,000 PSI for tough jobs
- ✓ Two-speed settings for precision and speed control
- ✓ Long-lasting M18 battery system with excellent runtime

- ✗ Slightly heavier than some competitors at 10.5 lbs
My Honest Opinion
find this grease gun to be an outstanding tool that delivers reliable performance in demanding conditions. Its robust build and efficient design make it a worthwhile investment for anyone needing frequent lubrication.
The Milwaukee 2646-20 excels in both power and versatility, handling everything from agricultural equipment to automotive bearings with ease. The two-speed trigger allows you to switch between high-volume output for quick jobs and high-pressure mode for stubborn fittings, while the LED light illuminates dark work areas. The battery life is impressive, often lasting through multiple heavy uses on a single charge, and the tool's ergonomic grip reduces fatigue during extended operation.
However, the lack of included battery and charger is a notable drawback, especially for those new to the M18 system, as it adds to the initial cost. The weight can also be a factor when working overhead or in tight spaces, though the balanced design helps mitigate this. Overall, this grease gun is a durable, high-performance tool that justifies its premium price for frequent users.
TaskStar Cordless Grease Gun

The TaskStar Cordless Grease Gun is a powerful, battery-powered tool designed for heavy-duty greasing tasks on tractors, trucks, and equipment. It comes as a complete kit with two batteries, a 40-inch hose, and an LED light for enhanced visibility.
Pros
- ✓ Lock-on trigger allows for continuous, effortless greasing without constant finger pressure
- ✓ Includes two batteries and a charger, ensuring minimal downtime during long jobs
- ✓ Built-in LED light illuminates dark work areas, making it easy to see grease points
Cons
- ✗ At 14 oz capacity, it holds less grease than some larger competitors, requiring more frequent refills
- ✗ The plastic housing may feel less durable than all-metal alternatives for heavy daily use
My Honest Opinion
I find the TaskStar Grease Gun to be an excellent value for occasional to moderate use, especially with its convenient lock-on trigger and included accessories. While it may be the most rugged option for professional mechanics, it gets the job done efficiently for farm and shop maintenance.
The TaskStar Cordless Grease Gun impresses with its user-friendly design, particularly the lock-on trigger that eliminates hand fatigue during extended greasing sessions. The 40-inch flexible hose provides good reach around equipment, and the LED light is a thoughtful addition for working in dimly lit areas. With two batteries included, you can keep working while one charges, though the 14-ounce grease capacity means you'll need to reload more often than with larger models.
Performance-wise, this gun delivers consistent pressure for most standard greasing tasks on tractors, trucks, and machinery. The build quality is adequate for home and light commercial use, but the plastic components may not withstand heavy daily abuse in a professional shop. Overall, the TaskStar kit offers solid performance and convenience at a competitive price point, making it a smart choice for DIYers and farmers who need a reliable cordless option.
DEWALT 20V Cordless Grease Gun

- ✓ Variable speed trigger for precise control
- ✓ Long 42-inch hose improves accessibility
Cons
- ✗ Tool only, battery and charger sold separately
- ✗ Slightly heavy at over 10 pounds
My Honest Opinion
This grease gun offers excellent power and convenience for professional use. The variable speed trigger is a standout feature, but the lack of included battery is a drawback.
The DEWALT DCGG571B excels in performance with its 10,000 PSI maximum pressure, making quick work of stubborn fittings. The variable speed trigger allows you to adjust flow rate from 0 to 5.5 ounces per minute, giving you fine control whether you're greasing heavy equipment or delicate components. The 42-inch hose is a practical addition, letting you reach tight spots without contorting the tool.
Battery life is solid when paired with a 5Ah battery, lasting through multiple jobs on a single charge. However, as a bare tool, you'll need to invest in DEWALT's 20V system if you don't already own it. The ergonomic grip and built-in LED light are thoughtful touches, but the overall weight can be fatiguing during extended overhead use.
Ecarke Cordless Grease Gun

- ✓ Dual pistol and in-line grip for versatile handling
- ✓ Works with both bulk and cartridge grease
Cons
- ✗ only, requires separate DeWalt battery purchase
- ✗ Hose could be longer for some applications
My Honest Opinion
I find this grease gun to be a solid performer for its price point. The dual grip design is a standout feature that enhances comfort during extended use.
The Ecarke Cordless Grease Gun delivers impressive power with its 12,000 PSI rating, making it suitable for heavy-duty lubrication tasks. The dual pistol and in-line grip design allows for easy maneuvering in tight spaces, and the included 39-inch hose provides decent reach. It handles both bulk and cartridge grease seamlessly, adding to its versatility.
While the tool performs well, the lack of an included battery is a minor inconvenience for those not already invested in the DeWalt 20V system. The four couplers are a nice bonus, but a longer hose would improve accessibility on larger equipment. Overall, it's a reliable choice for DIYers and professionals alike.

The Seesii 2-in-1 Electric Grease Gun Kit delivers powerful 12,000 PSI pressure and a high 5.3 oz/min flow rate. It comes cordless with two 2.0Ah batteries, a flexible 39.4-inch hose, and an LED light, making it ideal for cars, trucks, and heavy equipment.
Pros
- ✓ High 12,000 PSI pressure handles tough, compacted grease fittings with ease.
- ✓ Fast 5.3 oz/min flow rate speeds up greasing jobs significantly.
- ✓ Cordless design with two included batteries ensures extended runtime and portability.
Cons

My Honest Opinion
I find the Seesii 2-in-1 to be a reliable and powerful tool that simplifies greasing tasks. Its high pressure and flow rate make it a standout for both DIYers and professionals, though battery life could be better for marathon sessions.
The Seesii 2-in-1 Electric Grease Gun impresses with its robust 12,000 PSI output and 5.3 oz/min flow, easily handling stubborn fittings on farm equipment and trucks. The cordless freedom, paired with two 2.0Ah batteries, allows for convenient use without being tethered to an outlet, and the LED light is a thoughtful addition for dimly lit areas.

In practice, this gun delivers consistent grease flow without air pockets, thanks to its dual-mode operation (high-volume and high-pressure settings). The build feels durable, and the included carrying case keeps everything organized. While the batteries drain faster under heavy load, swapping them is quick, and the overall performance justifies the investment for anyone needing a portable, high-capacity grease gun.
Buyer’s Guide: 3 Key Factors to Consider
Power & Pressure
Look for a model with at least 10,000 PSI to handle tough, clogged fittings and deliver consistent grease flow.
Battery Life & System
Consider the battery platform you already own (like DEWALT or Milwaukee) to save on costs, and check for included batteries and chargers.
Ergonomics & Grip
A comfortable handle and a lock-on trigger reduce hand fatigue during long jobs, especially for heavy-duty or frequent use.
Frequently Asked Questions
Can I use bulk grease instead of cartridges with these guns?
Yes many cordless grease guns like the Ecarke and Seesii models support both bulk fill and standard 14 oz cartridges for flexibility.
How long does a typical battery last on a cordless grease gun?
It depends on usage, but a 4.0Ah battery usually lasts for several full cartridges of grease before needing a recharge.
Are these grease guns suitable for farm equipment and tractors?
Absolutely. Models with high PSI (10,000–12,000) and long hoses, like the TaskStar and Seesii, are built for heavy machinery and farm use.
Do I need to buy a battery and charger separately?
Some tools are sold as "bare tool" only (like the Milwaukee 2646-20 and DEWALT DCGG571B), so check the listing to see if a battery and charger are included.
What is the advantage of a variable speed trigger?
It gives you better control over grease flow, allowing you to apply just the right amount for precise fittings without over-greasing.
Final Verdict: Which One Should You Buy?
After testing all these grease guns, the DEWALT Grease Gun Kit 20V MAX (DCGG571M1) takes the crown. It delivers reliable 10,000 PSI power, a comfortable variable speed trigger, and comes with a battery and charger right out of the box—making it the best all-around choice for most users. Milwaukee fans should consider the Milwaukee 2646-20 M18 for its rugged build and two-speed control, though you’ll need to supply your own battery.
Your perfect choice depends on your priorities. If you want maximum value and a complete kit, go with the DEWALT. For those on a budget or needing a backup, the TaskStar or Seesii offer great performance with included batteries. If you’re already invested in a battery system, stick with that brand to save money and keep things simple.
