I'll do the math when I get home, but you can likely expect an electric compressor to hurt your fuel economy even more - because ultimately you're still drawing that power from the engine, but you're converting it from mechanical to electrical and then back to mechanical energy, with large losses with each conversion.

I would expect a compressor to drain a 12v battery flat in maybe 10-15 minutes, at a guess.
