Questions about Nitecore UMS4 USB quick charger

I was able to do some research and unfortunately we don't currently have a version with USB-C in our range. Unfortunately, I can't say at the moment if and when it will be added to the range. There is also a model from the same manufacturer with a power connection, if that is still an option: Nitecore SC4 Dieses Modell hat einen USB-C Anschluss: Voltcraft Rundzellen-Ladegerät

None. In my opinion, this is the biggest advantage of this product.

Correct.
