I'm sorry if this has been asked/suggested/spoken of before but I couldn't find it in a search of the board.

Is there such a thing as a small "battery pack" type device for the empeg? I assume this would be fairly easy. For example, when I had a Sega Game Gear it had a little potato shaped rechargeable battery that ended in one of those common power plugs that looks like the one for the empeg (although I'm sure it had a different amount of power - I'm not good with this type of stuff).

Anyway, does anyone know of something that could substitute for this particular purpose? All I want is something rechargeable and something that lasts for oh, say, 4 hours.

And if there are issues with this that I am not seeing, please alert me to them.
