The AOCHENG 21V Battery Powered Grease Gun is a cordless lubrication tool designed for efficient grease application in automotive, industrial, agricultural, and machinery maintenance applications.
Powered by a 21V lithium-ion battery, this electric grease gun delivers up to 10,000 PSI (700 bar) maximum pressure and provides a grease output of up to 130 g/min, allowing fast and reliable lubrication even in demanding working conditions.
With a rechargeable battery system, LED work light, flexible hose, and ergonomic handheld design, the grease gun helps improve lubrication efficiency while reducing manual effort for professional maintenance work.
Provides up to 10,000 PSI (700 bar) maximum pressure, allowing grease injection into difficult and blocked grease fittings.
The 21V lithium-ion battery system eliminates the need for power cables or air compressors, providing flexible operation in different working environments.
Delivers up to 130 g/min grease output for faster lubrication and improved maintenance efficiency.
Built-in LED lighting improves visibility in dark working areas, while the battery indicator helps users monitor remaining power.
Compatible with standard grease cartridges and bulk grease, suitable for NLGI #2 grease applications.

Compared with traditional manual grease guns, the battery-powered design provides continuous grease delivery with less physical effort.
The high-pressure output allows effective lubrication of machinery components used in construction, agriculture, and industrial applications.
The cordless structure allows users to perform lubrication work without external power supply or air compressor equipment.
The package includes essential accessories such as battery, charger, flexible hose, and grease coupler for immediate use.
A battery powered grease gun is an electric lubrication tool that uses a rechargeable battery to automatically deliver grease under high pressure. It is commonly used for machinery maintenance, vehicle servicing, and industrial lubrication
The AOCHENG 21V battery grease gun can provide up to 10,000 PSI (700 bar) maximum pressure, making it suitable for demanding lubrication applications where high-pressure grease delivery is required.
The grease gun is compatible with common NLGI #2 grease, which is widely used for automotive, agricultural machinery, construction equipment, and industrial lubrication.
The working time depends on the battery capacity, grease viscosity, pressure conditions, and operating frequency. A larger capacity lithium battery provides longer operation time for continuous maintenance work.
Cordless grease guns are widely used for lubricating trucks, tractors, construction machines, factory equipment, and other machinery where convenient and efficient grease application is required.
