Portable Car Jump Starter with Smart Clamps | 12V Battery Jump Box with USB Charging Ports

Clamps On, Current Flows

This 12V jump starter uses an internal lithium polymer battery and smart clamps for direct contact with vehicle battery posts. Two variants are available with peak output of 4000A or 6000A and battery capacity of 16000mAh or 20000mAh.

The clamp module includes polarity detection and controlled output at the clamp interface.

How the 12V Path Is Used

Attach the smart clamps to the battery terminals, then engage the jump output for 12V starting circuits. The unit includes two USB-A ports rated at 5V/2A each for USB-powered devices. An onboard LED light provides steady, strobe, and SOS modes, and the specified operating range is -22°F to 140°F.

Charge, Pack, Park It

Recharge using the included USB Type-C charging cable. Store the unit and cables in the included storage box to keep the smart clamps separated from other items. For basic care, wipe the housing with a dry cloth and keep the clamp jaws clear so metal contact is not obstructed.
