My charger has an output-Voltage of 6,15V (without the device connected to it) - So I asked myself if it is possible to charge the n810 (and run it directly) with an external 6V Battery (like this: http://www.online-batterien.de/shop/...erie6Vlose.jpg), just connected to a 2mm charging-Plug - without any electric circuit between.

What do you think? Could I demage it by doing that?
Actually, you need a regulated 5v supply to plug in to your power jack. A battery may start out at 6v, but it drops in voltage as you use it. What I suggest is using a 12v battery with a simple circuit that gives you a regulated 5v output. You can buy them in the form of an adaptor that plugs into your 12v power outlet of your car which has a dc output of 5v rated at a current of 1amp. I would buy a lead acid (rechargable) battery rated at 17 ampere hours.
