7.3 Powering a 12V DC Device:
The booster is a power source for all 12V DC accessories that are equipped with a 12V accessory plug.
1. Make sure the device to be powered is OFF before inserting the 12V DC accessory plug into the 12V DC
accessory outlet.
2. Open the protective cover of the DC power outlet on the front of the booster.
3. Plug the device into the outlet and turn the device on (if required).
4. If the device draws more than 15A or has a short circuit, the circuit breaker of the booster will trip and
disconnect the power to the device. Disconnect the device and the beaker will automatically reset. The
DC power outlet is wired directly to the internal battery. Extended operation of a 12V device may result in
excessive battery drain. Recharge immediately after unplugging the device.

The booster is a power source for all accessories that are equipped with a USB plug. The USB port provides
up to 2.1A at 5V DC.
1. Ensure the battery clips are securely clipped on the storage holders.
2. Press the USB button on the front of the unit.
3. Plug the device into the USB port on the front of the unit.
4. Turn the USB device on.
5. Reverse these steps when finished using the USB port.
NOTES: The USB port will shut-off automatically after 60 minutes, if no device is connected.
Extended operation of a USB device may result in excessive battery drain. Recharge the booster immediately
after unplugging the device.
