I lookded at a 200 watt "suitcase" model they've got and was just curious if they'd keep my two camper batteries charged with the vent fan going (with some windows open) while I was at the AirVenture grounds. I'm not sure what the amperage draw is for the fan, but can't be more then the 16+ amps it would put out at full sun. I might just see if I can find a 100 watt Renogy.
Thanks for the feedback everyone.
