Hello, does anyone know where I can find a rechargeable battery pack for electronic devices? Maybe something like a large brick that I can take with me and plug a guitar amp into? Or anything else, for that matter
If you don't mind lugging something heavy around, get a deep cycle automotive battery, preferably a sealed spill-proof type. Then get an AC inverter that puts out enough current to power your amp. A 500w inverter is enough for a 100w tube amp. To recharge, use any car battery charger. If you want to downsize that a bit, search yahoo shopping for a NiMh 12v battery pack. You will have to get a specialized charger, though. A car charger will destroy a NiMh pack.
