YD Car Jump Starter with Air Compressor

After we turn off the power of the car, clamp the red clip on the positive pole (+) of the battery and the black clip on the negative pole (-), then turn on the power of the starter (if there is a switch), start the vehicle, usually start within 5-10 seconds, disconnect the starter immediately after successful start, and remove the black clip first and then the red clip.

Charge regularly, even if not in use, every 3-6 months to maintain battery performance; at the same time, store it in a dry, cool environment, avoid high temperature, humidity or direct sunlight to prevent battery damage. In addition, avoid discharging to 0% for a long time to extend the service life of the battery.

If the starting attempt fails, check whether the starter has sufficient power (less than 50% may affect the starting effect), confirm whether the clamp connection is tight and ensure good contact with the metal part, wait 30 seconds and try again; if the starting attempt fails multiple times, the car battery may be damaged. It is recommended to further check or replace the battery.

The starting current determines whether the starter can successfully start your vehicle, and the battery capacity (mAh) affects how much power it can store. At the same time, safety protection functions (such as anti-reverse connection, short circuit, overheating protection, etc.) are crucial and can effectively improve the safety of use. In addition, the type of charging port also affects the charging speed. USB-C charging is usually faster, and additional functions such as LED lights can provide additional lighting convenience.
