The real life USB C experience has replaced the "which side is up" problem with the "is this cheaply made garbage electronic device going to charge at all with my $80 MacBook USB C charger", which it often does not (and instead requires a USB A to USB C charging cable)

I have also seen these issues and always wondered why this happened. There seems to be an issue with the tolerances of USB C compared to A that make C more susceptible to damage and also dirt and dust. The main issue seems to be lack of resistors in some devices, which leads to USB C not seeing the device to be charged as such, as it isn't negotiating the USB-PD part. USB A doesn’t officially implement a power delivery negotiation spec, it’s just always on at the charger end, with more amps possibly being negotiated if I’m reading properly. People seem to be able to resolve this issue with a daisy chain. Devices that usually only work with A to C cables might be able to use a C charger connected to a C to A (female) cord or A to C adapter, which is then connected with a standard A to C cable to the device to be charged. It’s probably easier to keep a USB A charger and A to C cable, but hopefully this helps put your mind at ease that there is a rational explanation. https://acroname.com/blog/why-usb-c-connections-sometimes-dont-work https://acroname.com/blog/why-usb-c-connections-sometimes-do... https://plugable.com/blogs/news/understanding-usb-c-charging-issues https://plugable.com/blogs/news/understanding-usb-c-charging... https://en.wikipedia.org/wiki/USB-C https://en.wikipedia.org/wiki/USB-C The Reddit post below actually explains how to work around the problem as I mentioned above: https://www.reddit.com/r/UsbCHardware/comments/w1ismo/how_come_some_devices_only_work_with_usba_to_usbc/ https://www.reddit.com/r/UsbCHardware/comments/w1ismo/how_co...

  oh im totally aware of there being a reason, it's just massively annoying because i deliberately seek out USB C stuff (which is thankfully becomming the default) and then frequently having to return it because the whole point for me is having a single charging solution and not 4 of them
