• How often should I recharge my UTRAI jump starter?

  It is recommended to recharge the device every 3 months to maintain battery efficiency and prolong its life, even if it has not been used.

• How do I know if the jump starter is ready to start the car?

  Connect the smart clamps to the battery (Red to +, Black to -). If the indicator light turns solid green (and stays on), the connection is correct and you can start the vehicle.

• What do the flashing red and green lights mean on the battery clamp?

  When the smart clamp is plugged into the jump starter, flashing red and green lights typically indicate that the device is in standby mode and ready to be connected to the car battery.

• Can I use the UTRAI jump starter to charge my phone?

  Yes, most UTRAI jump starters feature USB output ports (some with Quick Charge) that allow you to charge mobile phones, tablets, and other USB-powered devices.

• What should I do if the engine does not start on the first try?

  If the vehicle does not start immediately, disconnect the clamps from the car battery, wait for at least 20 to 60 seconds (depending on the model) to allow the battery to cool, and then try again.
