This is probably a silly question to those in the know :roll: But is it possible to charge the wifi extender while away from the computer, like on holiday?
Strap a 12 volt DIEHARD automotive battery to your back. You'll need a 12volt inverter and wall wart. ...Oh and a good backpack frame, preferably aluminum. This setup is a little heavy...but provides ample power for all your devices.
As well as being able to jump off your car should you need it.
A bit lighter then the helpful diehard idea, is a portable USB battery. I carry one so I can supplement charge if away from a wall charger (or a convenient car battery in my back pocket...)
