Also picked one up months ago. Mine also refuses to solar charge I have to charge it with a wired power cable like any other power bank which defeats the purpose of this entirely
You’re always better off with a separate solar panel with specs instead of one of these built in ones. These are amorphous solar panels (ie cheapest and worst possible design) that generate very little power per square inch. They probably can barely keep up with normal self discharge and if they aren’t designed properly with a diode to prevent reverse flow they can speed up self discharge. Proper design means extra components means extra $ means if they don’t say it in the specs it’s just a race to the bottom, cheapest price = garbage
