Hello, I am trying to figure out if it would be practical to put a USB 3.0 output onto a 10watt solar panel (as pictured)? As of now it has a USB 2.0 output. Also would it be practical to put a USB 3.0 input onto a small portable power bank? Anywhere from 5,000 mAh - 20,000 mAh. In theory it would charge noticeably faster correct? Or am I missing something? Would it not make economical sense? Thank you for any knowledge regarding the topic, AJ
