I think I may be somewhat confused regarding the USB outlets?? I'm pretty well versed on
electrical matters, both 120vac & 12vdc, as I've built & rebuilt (& wired) several campers. I've little or no experience with
solar but have considered some of the newer 'flexible' panels, especially since we've recently bought a 2001
Casita 17 SD. We own a Honda Eu2000i
generator which we carry in our TV, but seldom have to use it. We've gotten along for several years with a Motorola Droid 'X' cell phone & Verizon service. We're thinking of acquiring an iPad or similar. I've seen various devices that 'hook' to a USB port for charging but in looking at the 'cigarette' lighter type adapters in stores, I see some are 'Hi' & some are 'Low', with some combos. Question I have is - what is the difference & which would you use with which devices? Or, can they all be used with any device, with the difference merely lower/higher rates of charge? TIA...
