Spark Mini - Powerbank?

[Matthias Voigt]

Is it possible to use the Spark mini as a powerbank for an USB-C connected Samrtphone?

Thanks

@matthias-voigt I’m not a ‘YouTuber’ but it seems to be input for power only, not output too on mine.

@matthias-voigt I am not a YouTuber, but I have one of the super early bird Minis.

I tried: I connected my Google Pixel 4a with my Spark Mini with a USB-C-to-USB-C cable.

The phone tells me, and I also see on the Mini's LED, that the phone is supplying power to charge the Mini – not the other way around. The phone offers me to switch, but when I tap that option, a little while later it tells me that it was not able to reverse the charging direction.

Long story short: The Mini receives power, but doesn't send out power.
