Usually just the opposite is true, the new units are more efficient and draw less amps.
As to using an adapter, with the right adapter, not he hockey puck, but a dog bone type, it should work fine as long as it is only the a/c and the converter. Did it at many Rallies years ago when we went to Fairgrounds that only had 15 or 20 amp receptacles.
