I've used quite a few different USB chargers with my Kobos. Currently, I'm using a GaN 165W charger with 4 USB C and 2 USB A ports ( looks the same as
USB C Charger 165W on Amazon.it ) I was using a Ikea USB C/USB A charger but that was recalled due to an issue with the braided power cord cover so I picked this one up to replace it.
