F20 Wireless Power Bank 5000 mAh

I'm looking for a slim wireless power band to use with my OnePlus 13, and I am looking at the F20 Wireless Power Bank and the Kuulaa Ultra Slim (KL-YD71).

I have found the mini roundup by u/N8falke that is very useful.

However, does anyone have any experience of this F20 model?
