Mellif Cordless Grease Gun compatible with DeWalt 20V — 10,000 PSI Brushless, 5-Speed, 14 oz Cartridge

The Mellif Cordless Grease Gun is a battery-powered, DeWalt 20V-compatible tool (battery not included) that delivers up to 10,000 PSI with a 5-speed brushless motor and accepts 14 oz grease cartridges for fast, on-the-go lubrication.

This compact grease gun combines high pressure, variable flow control and a long reach to speed routine maintenance across automotive, agricultural and industrial applications. Designed as a tool-only unit compatible with DeWalt 20V Max batteries, it is intended for technicians and DIYers who need cordless convenience, an integrated LED for dark workspaces and safety features such as low-voltage protection and a lock button.

How fast and powerful is the Mellif grease gun?

The built-in brushless motor achieves up to 10,000 PSI and delivers a top flow rate of approximately 10 oz per minute on the highest setting, enabling rapid greasing when you need it. Choose from five speed settings to match pressure and flow to the job for controlled application and reduced waste.

• Up to 10,000 PSI output for heavy-duty lubrication
• Maximum flow ~10 oz/min on speed 5 for quick fill-ups
• Five variable speeds to tailor pressure and flow
• Brushless motor for efficient power use and longer life

What grease capacity and reach does the tool offer?

The grease gun accepts a standard 14 oz (400 g) cartridge, cutting down refill frequency for continuous tasks. A flexible 30" (76 cm) hose gives access to tight or recessed fittings without disassembly, helping you work faster and cleaner.

• Holds a 14 oz (400 g) grease cartridge for extended runtime
• 30-inch flexible hose for hard-to-reach grease points
• Integrated no-mar foot for stable placement without surface damage
• Air-bleeder valve to expel trapped air for consistent flow

What safety and convenience features are included?

The tool includes several user-focused features to improve safety and ease-of-use. A safety lock button prevents accidental activation, while low-voltage protection automatically disables the motor when battery voltage falls below 14.4V to protect both battery and motor.

• Safety lock button to avoid unintended starts
• Low-voltage protection shuts tool down under 14.4V
• Continuous pump mode for one-press flow without holding trigger
• Built-in LED light to illuminate work areas in low light

How does it integrate with DeWalt batteries and service options?

This model is sold as a tool-only unit and accepts DeWalt 20V Max batteries for users who already own compatible power packs. Mellif provides a 5-year warranty and customer support to help with service, parts and troubleshooting when needed.

• Compatible with DeWalt 20V Max batteries (battery/charger sold separately)
• Tool-only configuration ideal for owners of DeWalt battery ecosystems
• 5-year warranty backed by Mellif customer service
• Low weight (approx. 3.45 kg) for portability on jobsites

Who is this for? The Mellif Cordless Grease Gun is aimed at mechanics, fleet technicians, farmers and serious DIYers who want fast, cordless lubrication with selectable pressure settings and extended reach. If you already use DeWalt 20V batteries and need a compact, high-pressure grease solution with safety features and a long warranty, this tool offers a practical balance of power, portability and control.
