Just thought I'd let everyone know this, even though I know it is inconvenient. I installed a rear IPCam today which uses a cigarette lighter/charger port for power in my vehicle today and plugged it into the rear port on the back right. Pleasantly surprised to find that it is always on although the front two are not sadly. Maybe it will help someone else. Now I have to worry about a dead battery if I don't drive it often enough.
