Do not use the product as a car battery and do not use it to start the car while the jump starter is charging. Do not press the Boost Button before connecting to the car battery. Do not connect the red clamp to the black clamp. This product is only intended to start 12V vehicles and should never be used on non-12V equipment such as aircraft and 24V vehicles/boats.

Before starting your car, clean the battery terminals and inspect the jumper clamps for any damage. Dirty terminals and damaged clamps can affect performance. Fully insert the battery clamp’s blue plug into the socket. Failure to do so may damage the device. Repeatedly jumpstarting your vehicle in a short time frame will increase the likelihood of damage. To prevent this, ensure the jump starter has adequate breaks in between each use. If you are using the jump starter several times in a row, allow a 60-second break in between each use.
