Maybe we should spin this off into a "How USB-C Works" thread
I think a basic primer is a good idea, as many people think USB-C is just another plug shape change like when the micro sizes were introduced. So they are just looking for the same as they would have done before, i.e. a power supply and the right shape of cable on each side. My understanding is as below, am I basically correct?
- USB-C is the latest USB standard, but it is much more than just a better plug design. Not only does it feature a new, compact, reversible plug design, but it allows for smarter power solutions for modern devices.
- Connecting compatible devices with a cable that has USB-C on both ends will allow exactly the right power to be delivered to charge the device, reducing the risk of overpowering devices.
- You can in principle use a USB-A (full size) to USB-C cable but this is not optimal for powerful devices like tablets or the Switch console. So while you can use that kind of cable to charge your Pro Controller or Joy-Con, it may not be enough to keep the Switch powered and charging while you use it. It might "work" but it won't be ideal.
- Best setup: USB-C to USB-C end to end, with a quality cable that meets the spec, and a power source (either AC adapter or portable power bank) that meets the Switch voltage requirements. Which sources will meet the requirements is mostly speculation until the console launches and people start testing it out.
- Compatible but less than optimal setup: USB-C to some other form of USB cable, and/or a power source that does not meet the Switch voltage requirements.
