I have been following this forum for about three years. In that time I have had three different vehicles that I have lived in. All of my situations have allowed me to simply use a 30 amp pole with a cord or simply an extension cord. Now life is changing and I will be venturing out to do more boon docking. I need to get power for simple things like charging a laptop and cell and probably a fan here and there. Here's the problem.....anytime I read about electricity or batteries or solar, my mind completely shuts down and its like reading Russian for me. I have a huge block about all of this. I can read the basics and think I understand what needs to happen then in about 5 minutes all that information just disappears and I am left ignorant again. I can not seem to get around this! I have stood at Walmart ready to buy a battery and put it back cause once i have it I have no idea what I will do with it! ...BAH! I think I'm going crazy. Watts, amps, volts, hours, wire gauge, fuses, I think I'm gonna vomit! Anyone else having this problem?
