That's the 'inverter' he's talking about, Stingo, inversion is what happens to swap DC to AC. What he's wondering about is if the AC waveform that comes out of it (which is somewhat different than the true AC one that comes out of the wall), will make any difference in charging the Reader. I don't know enough about waveforms as they interact with transformers and power supplies to answer it, I doubt I ever did, actually. The Engineering Technology program I went through wasn't real big on theory, and that's where the answer is going to have to come from.
Is there an actual double-E in the house?
