This USB OBD II adapter works to power most OBD II GPS tracking devices that you don't want plugged directly into the vehicle OBD II port. Great for hard to access OBD II ports, OBD II port already in use and on board computer(ECU) security as the GPS isn't connected directly to the vehicle's system. This also allows you to install OBD II tracking devices in vehicles with no OBD II port.(older than 1996 vehicles, RV's, Semi-trucks, and boats) Works any where a standard USB port is present.

Can be powered of any standard USB phone charger, computer, USB battery bank, in vehicle USB port, any usb port or charger that has power!
