Or is that where an inverter comes in?
no, an inverter is if you want to generate AC from a battery. You don't need that. Quick electricity primer: Voltage needs to be correct for your devices. Too little and they won't work. Too much and they'll fry. Current is different: the device will draw as much current as it needs from the power source. It's determined by the formula V = I*R, where V is voltage, I is current (amps), and R is the resistance (ohms) of the device. So if V is right, and your power supply can produce *at least* I, then you're fine. -- "Welcome to Muppet Labs, where the future is made - today!"
