USB-C
  • The Nintendo Switch.
  • Most phones and tablets not from Apple in last few years.
  • Most recent ereaders, inc newer Kindles, but oddly not the Oasis 3rd version.
  • Some Apple gear.
  • Some power tools. They don't come with a charger and need 20V, so a USB-A to USB-C cable doesn't work.
Apple will be having USB-C instead of Lightning on iPhones, at least in EU and close trading partners, because it's now an EU directive for phones, tablets, cameras, ereaders and similar gadgets.

Not all USB-C devices will charge with a USB-A to USB-C cable, but all should work for data with USB-A as host and any that use a 5V charger will charge on a USB-A port. USB-C can use 20V up to 5A. A revision allows more because stupidly 100W was too low for more powerful laptops. It's still stupid as a laptop power supply or for high power because there will be laptops still not using USB-C for power and no laptop with USB-C ports is going to be able to charge high power USB-C devices. The USB-C port on my desktop PC doesn't evencharge my ereader as fast as my charger that has USB-A socket and it's not even a high power device.

USB has always been a bit of a mess and while USB-C works and solves a few issues it's a missed opportunity. The idea it could optionally carry HD video creates confusion. The more than 5V because someone thought it would be good to charge laptops was silly. The idea of laptops with only USB-C for power is silly.
