The PureCam is designed with an OBD-ll charger to allow use even when the car is turned off. That way your Parking Mode can detect if an accident occurs or if there is an attempted break in, and allows you to remotely stream from your mobile app.
The main power course, however, is a standard mini-usb cord so any power source would be able to power the device such as the DC charger port on your car. Using this is not recommended however as the device will not work once the car's engine has been turned off.
If you are having trouble accessing your OBD-II port or do not have access to it, please speak with your local auto shop for further assistant for installation or getting an adapter.
