I will never stop being irritated by devices that use a USB-C connector for their power input but that just require 5V without negotiating (and so are only useable with a USB-A power supply).
This seems to be a consequence of EU and Chinese initiatives to standardize on USB-C for mobile device power, with cheapskate vendors “complying” by simply swapping in USB-C connectors for micro-USB without changing the electronics.
An even more broken version of this, which I’ve encountered occasionally, is USB-C devices that not only require a USB-A power source, but also only work if the USB-C connector is inserted one of the two possible ways.
@mattblaze I have a speaker that's USB-C power for recharging. Came with C-A cable. *only* charges with that specific cable. Other C-A ones do not work. A Tribit if I recall right.
