The AGM batteries have a key difference to wet cell batteries in that they can be recharged up to three to five times as fast. If you get a charger sized for the task, you can put back the energy for the hair fluffing almost as fast as she uses it, with that little Honda generator or by driving and charging from the alternator. I would look for a 2,000 watt pure sine inverter, a 50 amp or so charger (built in or a separate converter type unit) and I like 230 amp hour 6 volt golf cart batteries, four of them in series/parallel for the 12v bank.
