How to use

Before use, confirm the vehicle uses a 12V electrical system and ensure the jump starter is sufficiently charged. Turn off the vehicle ignition and connect the positive clamp to the battery positive terminal and the negative clamp to a suitable chassis ground or negative terminal. After secure connection, attempt to start the engine. Once the engine runs, disconnect the clamps beginning with the negative clamp and then the positive. For auxiliary charging, connect compatible devices to the powerbank output according to the device’s charging requirements. Follow the manufacturer’s marking on the unit for connector orientation and charge indicators.

Usage recommendations

Store the jump starter charged and in a dry place; periodically recharge it according to usage frequency. Do not use the starter on batteries with severe physical damage or visible leakage. If the starter does not produce expected cranking current, check connections and battery state before repeated attempts. Use only within the temperature range specified by the manufacturer and consult the user manual for detailed safety instructions.
