Product Information
Full details
The YUSMAN F04 is designed for motorists and outdoor enthusiasts who need a reliable, high-capacity portable power source for emergency battery jumps and tire maintenance. With a massive 5000A peak current and 21800mAh battery, it efficiently starts even the largest 10.0L gasoline or diesel engines while providing an integrated air compressor for tire inflation. While its high-capacity power allows for multiple jumps on a single charge, users should be aware that the device is relatively large due to its heavy-duty build, making it better suited for trunk storage than a glove box.
