Answer to: Teardown of Nintendo Switch already pubished? Memory upgrade?Even if they make a 64 or 128 version, we don't know if they will use the same chip or connector. Don't count on it just yet.
Answer to: How to charge a Nintendo Switch in the car!Regarding USB-C connectors, those are not rated for any particular voltage as they do also charge things like the Macbook/Macbook Pro, A lot of other Windows Laptops, The Chromebook Pixel, Cell Phones... and all of these are rated at different outputs. My best guess is that the system can be charged at 5V, but charges faster (and probably while playing it) at 15V. Kind of like you can charge an iphone with their 1 amp iphone charger but it also charges faster with the ipads 2.1 amp charger.
