I’ve tried using different USB-C power supplies from various manufacturers (some generic, some premium) of various maximum wattages, but the only one that works is the one which came with the RS90. That one will work with every cable I throw at it, and with either the charging base or plugging directly into the port on the base of the remote itself.
Are you having the 1GB version? because that only supports low power chargers.
It looks like mine has 8GB of storage if that’s what you’re referring to…
I received this remote as a gift for my patience as we wait for the RS90X to come out, so I don’t know the specs.
Looking at the rating on the working USB supply, the output shows 5V=3A, 9V=2.22A, 12V=1.67A (20W MAX). That seems pretty standard, and after all… The U in USB stands for Universal, which is asking to my confusion.
There is no fast charging on the 1GB version nor the dock supports fast chargers so use Usb A to C type cable. Usually those bricks are also low power chargers.
