I'm an RC newbie just about to buy my first plane, a Multiplex Easyglider Electric. It comes with charger which hooks up to a car battery. All the other chargers I've seen at Hobby Lobby appear to be of the same type.

The issue is I'm in Tokyo where owning a car is more trouble than it's worth. I would need to take a half hour train ride to get to a flying field. Does anyone know of another way I could charge the plane? Something I could throw in a back pack without killing myself?
