On a past trip some years back I powered my car Tom Tom sat nav with a socket taken directly off the 6V battery. Apparently they operate at 5,5V and above Managed to get there and back without losing my way!! Also in the absence of a properly accurate speedo I used a cycle computer from Lidl wired up just to get a longer wire from the rear wheel from the sensor!! I think it cost about £5.
