Not that I'm in the habit of recommending their products, but have you
considered the MFJ-4416B Super Battery Booster? They claim the
switching regulator efficiency is over 90% and that it will regulate
down to 9V input.
They also have a GoesInna-GoesOutta remote monitor (MFJ-4416BRC) for

I believe they've been reported by different people in various ways and
