Charging a solar powerbank with external solar panels?

Hiya, I hope I’m not completely in the wrong place (/c/Technology seems to only be dedicated to tech news but not questions). I have this powerbank with a built-in solar panel. The powerbank itself seems great so far, but it’s a pretty tiny solar panel. I’ve read about the difficulty of just hooking up a regular powerbank...

You would not be able to accomplish this without an inverter setup. The only way those little powerbank things work is because those panels barely charge the bank, and the charging happens at a trickle rate that doesn’t harm the cells with current variation.TLDR the power bank is just normal battery cells, the panels are just a bit gimmicky.
