I know and have solar power access that can provide 2A at 6V put into 4xD which floats around 5-6V. This means I get 5-6 hrs at 2Ah, for 10AH, that when I use to charge gets stored in the 4xD, that are 10AH. So on a typical camping trip i use some from the 4xD and during the next day i recharge some of the devices and power banks that got used during the night. What I want and can do is power most of the USB devices I have. But I am looking for keywords to look for in USB hubs that can power multiple devices at the same time at their full rate since i am pulling power from 4xD batteries i can charge quite a few devices at the same time. Some USB hubs are USB 2.0, USB 3.0 but when used without a computer will now power the USB hub. I know I can just buy the USB connectors. So what do I look for in a USB hub that i am not really using for USB data, but using for USB power? Or how do you know it will work when you just have power to the hub and it will power or charge the devices? What is labeled or what key words do I look for when shopping for the USB hubs? I know I can and am handy with a soldering iron and multi meeter but if I don't have to that would be great. And the packaging of the USB hubs is nice, compact and looks good. Dreaming of camping or aquaponics and the pond.
