if charging off a generator is it best to use the DC part of the generator or should I use a car charger or use the 130v electrical supply to the popup through the converter? I have a 2013 Flagstaff HW27 ks. I also have a 2013 Powerhouse 2000Wi generator and it has a 12v DC supply at 8.3amps. so I was wondering if it would be best and fastest to use just the charger on the generator. we were out last winter in the desert (Red Rock Mojave) and after 4 days with charging with the converter in the camper we almost lost all power. the electric lift almost didn't have enough power to take the top down. we charged every day with the campers 130v cable plugged into the gen.6 to 9 hours a day. it might just be that we didn't charge enough on the last day. thanks for your info in advance.
