Seems like a decent deal (tell me where you got it if you don't mind) ... but one worry: tech specs says it can handle 15 A max. Is that enough? At first I thought not, but then I did the following calc, which I believe determines power from the voltage and current of a sine wave: 110 V x 15 A x 1.414 = 2,333 watts ... that actually seems like a lot since it would be 2 hair dryers running at once
