I have a chance to record a house being demolished. Only problem is, I have only my laptop and a MOTU Traveler. I know the battery on my lappy will not last throughout the demolition. Is it a good (safe) idea to use a power inverter? If so, would I simply determine what my equipment draws to figure out which inverter would be best to use? I have to admit I know very little about the subject. Have any of you tried this before? I'm guessing I'm setting myself up for noise being introduced, but it's really my only option, other than record just a few hours. Thanks!
