Dongar adapters allow you to quickly create a power source for your USB-powered dash cam, radar detector, or any other USB-powered gadget by harnessing the power already flowing through your vehicle. Simply unplug the power source in your dome light cavity and replace it with the adapter to power your dash cam or other USB device. Your result: one of the easiest, cleanest installs possible – no hardwiring, no time spent routing and hiding wires in your vehicle, and no distracting wires hanging across your windshield.
