Unless they've changed this with a recent production run, the charging port on the Voice Remote Pro is USB-micro, not USB-C. I'd very much like to see a USB-C port myself, if only because one doesn't need to struggle with the orientation of the plug in a semi-dark room, but from what I've read USB-C requires paying a licensing fee, so Roku being Roku ...
My oldest Voice Remote Pro is just now 2 years old and is still going strong. FWIW I find I have some USB-mini cables that make a wobbly connection and I have to jiggle them around to get the Pro to charge. I have some others that plug in more firmly and just work.
