Designed for compact storage and quick emergency use, the unit incorporates an 18,000 mAh lithium-ion battery, a digital charge-level display and an integrated USB power bank.

Advantages

How to use

Before use, ensure the jump starter is fully charged and inspect the clamps and cables for damage. Connect the positive clamp to the vehicle's positive terminal and the negative clamp to a suitable chassis ground or negative terminal. Power on the jump starter according to the device controls, then attempt to start the vehicle. Once the engine starts, disconnect the jump starter clamps in reverse order and allow the unit to cool if necessary. For charging electronic devices, connect cables to the USB outputs and monitor the device charge level via the digital display.

Usage recommendations

Keep the jump starter charged when stored in a vehicle and recharge after each use. Follow safety instructions to avoid reverse polarity and do not attempt to jump-start damaged batteries.
