Voltage and Pressure
Higher voltage does not automatically mean higher pressure, but it does correlate with runtime and motor capability:
- 12V: 6,000 PSI. Lighter and more compact. Sufficient for standard automotive maintenance.
- 18-20V: 8,000-10,000 PSI. Heavier. Handles severely seized fittings on older equipment.
For farm equipment, heavy trucks, and construction machinery: 20V with 10,000 PSI capability is the correct choice.
For passenger cars, light trucks, and trailers: 12V at 6,000 PSI handles all standard automotive zerk fittings.
Battery System Compatibility
The most important factor after pressure is battery system compatibility. DeWALT 20V MAX, Milwaukee M18, Makita LXT, and Ryobi ONE+ each have broad tool ecosystems. Buying a grease gun on a battery system you already use eliminates the cost of an extra battery and charger.
If you have no existing cordless tools: the EPAuto and Ryobi kit options include battery and charger.
