So just to add to my question and explain some of my assumptions (which may be incorrect):
I don't know that much about the conversions between voltages work. Any info I can get in that regard is going to help me out a lot.
My understanding is that going from 5V to 7.6V is fairly inefficient (I will lose some power) but that going from 12V to 7.6V is much less inefficient ^sorry ^for ^the ^double ^negative (I will lose much less power).
If these are correct assumptions, I'm better off getting something that can output 7.6+V e.g. this.
Based on research so far, the panel I think I want is here but it outputs at 5V. I don't know if that matters. Is that going to reduce my efficiency?
Because the panel outputs at 5V am I best off also getting a powerbank that outputs at 5V and just doing the conversion at the charger?
It seems like I have decent options. At this point just trying to figure out which one of them wastes the smallest amount of power.
How about the BigBlue or the RAVPower?
