I may have asked this before but I need a refresher now because its getting closer and closer when I am finally going to get a van. During the day I will not be using my van. Whats the EASIEST way to charge my battery for the night? I will either be using a heater(200 watt) or a small and I mean the smallest dehumidifier in the summer. Maybe the fan too. I have the battery /electric fan. Small stuff I won't be charging at all in the van. I will be work camping. So my computer,small batteries and phone will be charged before I leave work. I do this now. I also drive for work so the boss can't say anything about his electric bill. Correct please if Im wrong. I was hoping to attach a extra battery to my alternator. I was told because Im not going to be driving around a lot it may ruin my batteries? If I use solar whats the best watt for me and I need to put it on the windshield. Please in simple terms ...numbers confuse me no matter how often I reread something.
