It is a 150w panel and trying to keep it facing the sun and it could not get the bats charged up before I needed them at night. We camp mostly in the winter so the furnace runs a lot, I also use a CPAP. The effort of getting everything out, setting it up chasing the sun with little value, is more a "pain in the ass" didn't know I could say it fully in the forum.
So I can last 3 nights on bats, fighting to keep them fully charged wasn't worth it. Now if they get to run down I get the gen out and give them a boost. 1 item, 1 pull and done.
