I know this subject has been beat to death but wondering what others use strictly for keeping batteries charged only. Since moving back to Texas and close to the coast I would like something for an emergency just in case we have to vacate quickly, ie, hurricane, or whatever. I only want to charge the three batteries and won't use anything but 12 volt power. We have the Samsung fridge with inverter. Trying to keep weight at minimum and able to use like in a rest area or whatever. No AC, microwave or any things like that. Been looking and there is a million small generators out there, mainly interested in what the good people with Keystones use for small, easy to use gens. 2 stroke, 4 stroke? size ? etc. Thanks
