Jump-Starting Your Car
- Turn on the function button and make sure it is over 40% charged. If the power is less than 40%, it may not be able to start your engine.
- Plugin the jumper cables. The indicator light will flash red and green alternately when it is on standby. Before starting your car, please make sure the indicator light on the clamps is turned to steady green. If you don’t connect the clamps with the jump starter and the car well, the indicator light will stay red.
- Connect the red clamp to the positive terminal (+) and the black clamp to the negative terminal (-) of your car battery. When the indicator light turns to steady green, it means that the clamps are connected well and it’s ready to work.
- Start your engine.
- After successfully starting your car, remove clamps and pack away.
Operational Warnings
- To avoid serious injury to a person or damage to the jump starter, never attempt to connect the two clamps together. Connecting the positive and negative poles of the wiring will lead to short-circuiting, which is very dangerous.
- Important: When using the device, only the original charger and clips that come with it are allowed. Please confirm that the clips of the jump starter clamp the positive and negative poles of the car battery correctly. If the positive and negative terminals are reversed, it will cause damage to the vehicle.
- Please fully charge the device before the first time use. And recharge it at least once every three months to prolong its life span if you don’t use it for a long time.
- Avoid overpressure. Please check the car voltage carefully. For example, a 12V jump starter can start a 12V car but not a 24V diesel car.
- Please don’t start the car continuously, between starting twice you should allow an interval of at least 30 seconds to 1 minute.
- Please don’t charge the device immediately after starting the car to avoid damage to the battery.
- Please turn off unneeded appliances before starting your car with the device, such as car air conditioners, headlights, high-power speakers, and devices on the cigarette lighter. It will help start the car in an easier way.
