With all the power outages being caused by Hurricane Irene, I thought it might be useful to have an inverter that I could charge my cell phone with. Plug in battery power on one end, cell phone on the other. I've poked around a bit and found this schematic:
So a few questions...
First, would this work? Second, would this damage my phone or whatever device I charged with it (a 3DS for example)? Third, how fast would this drain say, a 9V battery? Is it even feasible to do this?
EDIT: I've just been notified it sounds like I'm trying to build a charger. This is not the case, I'm shooting for a power source that I can plug chargers into. Also, I just realized, is this outputting 120V or 120V RMS?
And I'm sure it's obvious, but just in case, I'll be building this thing myself..because well..I like building things!
