The VIOFO hardwire kit is suitable for most cars and trucks (accepts input voltages of 12-24V). Free up your cigarette lighter power outlet for another device such as your cell phone or USB charger.

VIOFO's hardwire kit will enable parking mode safely: the kit will automatic power off when your car/truck battery voltage is detected to be too low, this will prevent your vehicle battery from dying. The low voltage cutoff threshold is adjustable in 4 increments from 11.8 to 12.4v DC (12v systems) or 23.6 to 24.8v DC (24v systems).

This hardwire kit can be used by almost all miniUSB devices like dash cams, GPS navigation devices, radar detectors etc.
