Can I charge the powerbank while simultaneously charging another device (passthrough charging)?
And is the powerbank suitable for 24h operation of a Raspberry Pi, i.e. does it stay on all the time (always on mode) or does it switch off automatically after a certain time?
Thank you!

Accepted Answer

Passthrough charging does not work, no matter which combination of input/output connections I use.
I was able to operate a starry sky projector with 5 watts power consumption through the night with the powerbank, so a Raspberry Pi should also work.

Answer

According to the User Manual, page 3, a paragraph under the highlighted "or" applies:
"While the powerbank is charging, no other device can be charged via the powerbank".
I once connected a smartphone with USB-C to the powerbank and wanted to charge a tablet via USB-A at the same time.
USB-A at the same time. Result: The device discharged the smartphone connected via USB-C and used it to charge the tablet.
Remember: USB-C is both input and output!

I'm sorry, but I haven't tested that myself yet.
