Important Information
Usage & Safety Guidelines
Before First Use
Fully charge the jump starter using the included USB-C cable before initial use.
Read the user manual carefully to understand all functions and safety instructions.
Jump Starting
Ensure the vehicle is in park (or neutral for manual transmission) and all electronics are turned off.
Connect the red clamp to the positive (+) terminal and the black clamp to the negative (-) terminal or a non-moving metal part of the engine block.
The green indicator light on the safety detection cable confirms proper connection. Do not attempt to jump-start if the red warning light appears.
Do not use the jump starter if the battery is damaged, frozen, or leaking.
Air Compressor Use
Select the correct inflator mode and set your desired pressure on the LCD screen.
Attach the appropriate nozzle and connect to the tire valve. Press start—the unit will automatically shut off when the preset pressure is reached.
Do not operate the air compressor continuously for more than 10 minutes. Allow the unit to cool between uses.
Power Bank & LED Light
Use the USB or USB-C ports to charge mobile devices when a wall outlet is unavailable.
Press and hold the light button to cycle through Flashlight, Strobe, and SOS modes. SOS mode is ideal for emergency signaling.
Storage & Maintenance
Store the device in a cool, dry place between uses.
Recharge every 3–6 months to maintain battery performance.
Keep away from children and avoid exposing the unit to extreme heat, fire, or prolonged direct sunlight.
