This lockable wall bracket turns the Juice Booster 3 air mobile charging station into a fully-fledged wall charging station. The Juice Booster 3 air 3 air can be hooked in with a flick of the wrist and removed just as easily for use on the road. While the variant without locking is preferred in private garages, e-car drivers in public parking garages tend to opt for the lockable variant. This effectively secures the device against theft. Apply the drill twice, screw it tight - and that's it.
