It depends on the device you are charging. I can charge my Huawei MateBook at least four times.

I also ordered this powerbank! After 1 day, 2 out of 3 connections went out! So only the middle usb-c port was still working! I can still use it but at this price it's annoying...

As luck would have it, I just sent it back yesterday 28.06.21. The powerbank worked well for about 6 weeks, then problems occurred - no longer charges fully on wireless - then 2 of 3 cable connections failed - sorry insofar not the right answer.
