How to Use it

When using the GB10S for the first time, first verify the voltage and chemistry of your battery. Then connect the X-connect clamps to the jump starter, if not already connected. Confirm the battery clamps are connected to the correct polarity battery terminals. Then disable the vehicle’s accessories, making sure the vehicle’s power loads (headlights, radio, a/c, etc) are turned off before attempting to jump start the vehicle. Press the power button to be jump starting. If your clamps are connected correctly, the four led lights will begin to chase. If they are connected incorrectly, the error light will illuminate. When everything is connected properly, try to start your vehicle. If it does not start immediately, wait 20-30 seconds and try again. Allow the jump starter to rest for 15 minutes between jump starts. Once your vehicle has started, disconnect the clamps and remove the jump starter and place back into provided case.
