NOTE: If the GBX55 unit is not powered on first, it will drain power from the USB device, if it is DRP compatible. To charge GBX55 with a DRP compatible device

(e.g phone, laptop, power bank) ensure GBX55 is powered OFF before making a cable connection between GBX55 and the DRP device.

Step 2: Connect to the Battery.

Carefully read and understand the vehicle owner's manual on specific precautions and recommended methods for jump starting the vehicle. Make sure to

determine the voltage and chemistry of the battery by referring to your battery owner's manual prior to using this product. The GBX55 is for jump starting 12-volt

lead-acid batteries only. Before connecting to the battery, verify that you have a 12-volt lead-acid battery. The GBX55 is not suitable for any other type of battery.

Identify the correct polarity of the battery terminals on the battery. The positive battery terminal is typically marked by these letters or symbol (POS,P,+). The

negative battery terminal is typically marked by these letters or symbol (NEG,N,-). Do not make any connections to the carburetor, fuel lines, or thin, sheet metal

parts. The below instructions are for a negative ground system (most common). If your vehicle is a positive ground system (very uncommon), follow the below

instructions in reverse order.

1. Connect the positive (red) battery clamp to the positive (POS,P,+) battery terminal and the negative (black) battery clamp to the negative (NEG,N,-) battery

terminal or vehicle chassis.

Step 3: Jump Starting.

1. Make sure all of the vehicle's power loads (headlights, radio, air conditioning, etc.) are turned off before attempting to jump start the vehicle.

2. Press the power button to begin jump starting, and all LEDs will flash once. If you are properly connected to the battery, the white boost LED will illuminate and

the battery charge LEDs will chase. A 60-second timeout countdown will begin as soon as a battery is detected.

3. Try starting the vehicle. Most vehicles will immediately start. If the vehicle does not start right away, wait 20-30 seconds and try again. After the 60-second

timeout is complete, the unit must be powered off, then back on, to initiate a new jump-start sequence. Do not attempt more than five (5) consecutive jump

starts within a fifteen (15) minute period. Allow the GBX55 to rest for fifteen (15) minutes before attempting to jump start the vehicle again.
