My first post here so i hope this is in the right section! Sorry if not.

I'm after a voltage changable power supply that runs off a 5v USB port. I want to be able to run my camera off it (Canon G7 - 7.4v) while doing timelapses.

Any ideas?
 
I seriously doubt you could find anything like this. Even if something could change the voltage as you wish, I doubt you could get enough amps to power it though the USB port. Maybe I'm wrong, but I have seen some very picky computers...
