A:Answer This camera is strictly run via power from the car, there is no internal battery in the camera to replace The cigarette lighter loses power by design when you turn the ignition off, so the camera will also lose power, that's not a fault with the camera. Anything plugged into the cigarette lighter works like that.
If you want continuous power you'll need to use something other than the cigarette lighter.as a source. You'll need to connect the camera power cord to either an "always powered" fuse in the car's inside fuse box, or splice the power cable into another car cable that is also always powered. That one is not advisable unless you are certain what you are doing. There's a video on the Best Buy product page that shows the fuse connection method.
