You might want to have a look at the Nitecore UM4 it's USB powered but really designed to use a QC 2.0 compatible USB source (5V/2A). If the solar panel puts out 5V/2A then all is good, otherwise it would be a slow charge.

Here is the place I get my stuff from nowadays,
Liquid Nicotine - Nicotine Salts | Liquid Nicotine Wholesalers

Edit: I seem to still say "TPA" instead of "TFA" although they are the same company.
