Sorry for all the questions, I'm new at this. I just got the 100w Foldable Solar Suitcase Battery Charger and the PWM controller as a part of it. I see it has a place for "Load" output. Could I hook up a cigarette lighter type plug to that and then plug into that a typical USB charger into which I could plug a cell phone for recharging? If so, would it need to be fused?
Thanks again!

First off, no need to be sorry about all the questions. That's what this forum is for! Ask as many questions as you want/need to. You never know when your question (and hopefully an answer) will benefit someone else down the road. Now that we have that out of the way, on to the load output. Yes, you can absolutely hook up a cigarette lighter plug (or, better yet, a cigarette lighter socket) and plug those typical "car usb charger accessories" into it. Most of those only draw a maximum of 2A each...which is way below the maximum rated current spec for the load output terminals on the controller. In fact, that's exactly how I have my system configured. I have LED lights, a 12V fan, and various chargers for my cell phones, tablet, and other goodies plugged into it. Works like a charm! As for fusing, most of those 12V to USB chargers have fuses built into them. Still, I always like to have extra fuses in line just in case. True, the controller has built in protection, but 30+Amps at 12V is 360+watts...quite a bit of heat before the controller cuts the load. The most I ever draw from the load terminals is around 5 amps and usually no more than 3 or 4....so, a fast acting 10A fuse is what I'm using right now. Hope that helps. |
