Do you know those computer backup batteries? How well would one of those work to power a studio strobe on-location? They are getting cheaper and can be found on-sale...which makes them a fair bit less expensive than a Vagabond type system.

The APC UPS's? Not very well. They provide like 15 minutes of power.

No.... now that is based on absolutly zero knowledge of why. Some smart cookie will fill in the reason. But I'm interested to hear and would love to be wrong on this one.

I suspect that it can't handle the amount of power that the flashes would demand of it. If a computer can wear out a APC UPS in under 10 minutes (my pc does anyway), I can only begin to imagine what it will do when subjected to flash units..

Average computer is what? 350 watts? Monitor probably 80ish? I'm probably wrong. Plus some of them like to scream like crazy when they're not plugged in.

A friend of mine thought that it might work and I was curious if anyone had tried it. I guess I could look up the specs and figure it out myself.
A Vagabond system is only $300 anyway...

I dont know why it wouldnt work. Computers have a conisstant draw. Flash heas only have a large draw when they are being recharged from a flash. It would be interested to try and see.

Would the pure/true sine wave characteristics come into play on these UPS units too?
