Anyone know of a rechargeable battery setup that would power my Logitech z2200 system for guitar/vocal. Like for busking at farmer's markets or anywhere people are gathered. Just a guy and guitar. Well, and a mic.

Carvin makes a Stagemate deal that's a battery powered speaker system, which is an option. It's $400. Maybe there's a rechargeable battery gizmo for less that would work?

And if you have any knowledge if it would work with a keyboard...
