I just selected a bunch on AliExpress. Some were microUSB some were USBC. Some were a bit temperamental about charging. I usually take that approach with the really cheap items getting things from multiple suppliers so that at least one works. In general the worst I have received is poor quality items, nothing completely broken or fake yet*
I got two seemingly identical super bright panels and one now emits only 5% of the light. They look the same, have been run in the same conditions (and indeed the same housing now) run parallel off the same source. The other one is as bright as when I got it. Maybe one dodgy LED bringing the team down? I'm not yet skilled enough to diagnose problems like that.
*except for the time the store sent me a message to say I should cancel the order because they ran out. I couldn't find anywhere in the ever changing AliExpress user interface to cancel the item, so they sent me an allen key, I logged it as "item not as described" and they paid the refund.
You probably bought the same ones I did. How long have you had them for? They were awesome initially, but as I said, they quickly lost their charge, and it happened to all of them (but to varying degrees).
