How To Use
Step 1: Charge the GB500.
The GB500 comes partially charged out of the box and needs to be fully charged prior to use. Connect
the GB500 using the included 12V Adapter or 56W XGC Power Adapter to the 12V IN port. The GB500
must be in 12V mode to be charged. Ensure the voltage selection knob is in the 12V position prior to
charging. The XGC 12V IN port is rated at 12V, 5A to ensure safe and efficient charging of the internal
lithium battery. Due to FCC regulations, we recommend not to charge and discharge the unit at the same
time. The time to recharge a GB500 will differ based on the discharge level and the power source used.
Actual results may vary due to battery conditions.
When recharging, the charge level of the internal battery is indicated by the Charge LEDs. The LEDs will slowly pulse "On"
25% 50% 75% 100%
and "Off", and become solid until all four Charge LEDs are on. When the battery is fully charged, the Green 100% LED will be
solid, and the 25%, 50% and 75% Charge LEDs will turn "Off". From time to time, the Green 100% LED will pulse indicating
maintenance charging is occuring.
12V DC Charging (60W).
The GB500 must be in 12V mode to be charged. Ensure the voltage selection knob is in the 12V position prior to charging. Connect the 12V Cable to
the 12V IN port on the GB500, and the other end to the Male 12V Plug. Plug into a powered 12V AUX Plug (Cigarette Lighter Port).
AC Charging (56W).
The GB500 must be in 12V mode to be charged. Ensure the voltage selection knob is in the 12V position prior to charging. Connect the XGC 12V
Cable to the 12V IN port on the GB500, and the other end of the 56W Power Adapter to AC power (100-240VAC Wall Outlet).
Powering Your 12V Devices.
The GB500 must be in 12V mode to enable 12V OUT. Connect the 12V Cable to the 12V OUT port on the GB500, and the other end to the Female
12V Plug (12V AUX / Cigarette Lighter Port). Plug-in any standard 12V device (up to 15A) with a 12V plug and turn the GB500 "On" to start powering
your 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 system by referring to your vehicle's owner's manual prior to using this product. The GB500
is for jump starting 12-volt and 24-volt lead-acid battery systems only. Before connecting to the battery, verify the battery system voltage. Ensure the
voltage selection knob is in the correct position (12V or 24V) matching the battery system being jump started. Never change the voltage while the unit
is connected to a battery. Only change the voltage while the unit is off. The GB500 is not suitable for any other type of battery systems. Identify the
