Understanding LED Indicators
The jump starter features LED indicator lights that display the battery charge level. Each light typically represents approximately 25% of the battery capacity. Ensure at least two lights (50% charge) are illuminated for reliable jump starting.
Operating Instructions
Jump Starting a Vehicle
- Ensure the jump starter has sufficient charge (at least 50%).
- Turn off your vehicle's ignition and all accessories.
- Connect the smart jumper clamps to the jump starter's jump start port. Ensure a secure connection.
- Connect the RED (+) clamp to the positive terminal of your vehicle's battery.
- Connect the BLACK (-) clamp to the negative terminal of your vehicle's battery.
- Once connected, the indicator light on the smart clamp unit should turn solid green, indicating a safe connection. If it flashes or shows red, check connections and troubleshoot.
- Start your vehicle's engine. If it doesn't start immediately, wait 30 seconds before trying again. Do not crank for more than 3 seconds per attempt.
- Once the vehicle starts, immediately remove the black clamp, then the red clamp, and finally disconnect the smart clamps from the jump starter.
