while able to charge successfully, be aware, if using Chargehub, will need to tap into Tim Short Guest wireless network to use app to start charge... cellular svc too weak.. BIG COMPLAINT - cannot simply use charge card, both stations unresponsive. BIG COMPLAINT.. screen facing sun, washes out display almost totally. Tip.. connect car first, then open app, hit start charge... it SHOULD figure out which port you ate connected to and awaiting charge...
