Question:

Hello, Great response about my AC, so here is another one. My goal is to be able to run as many appliances while dry camping on my 12v battery. I want to be able to leave the camper for a few hours go fishing/swimming and have the appliances on, battery charging/maintaining and get back to a battery not drained. With my goal in mind I am looking for a solar charger: PTW2997 or A solar battery maintainer? BRW54FR Thanks again,

Expert Reply:

That amount of amperage/wattage that the two charger kits you mentioned are capable of really wouldn't be adequate to charge a depleted battery. Especially in a day as they are more designed to keep a battery topped off in storage more than anything. These both can put out up to 7.5 watts.

You'd want something with more output than that like the Goal Zero Boulder Briefcase Kit part # 287-32408 which is rated for 100 watts.
