Respuesta a "How to charge a Nintendo Switch in the car!"USB-C by default runs on 5V, like every other version of USB. This allows you to plug a USB-C charger into any device, without blowing it up. The Nintendo Switch however supports USB-C Power Delivery specification at 15V. When you plug it into the AC adapter the Switch pulls 5V but then asks the PSU "Do you support USB PD? I'd really like 15V 2.6A please.". The PSU then responds saying "Here you go." and switches to 15V. The Nintendo Switch only needs 15V when in docked mode as it uses twice as much power, its perfectly happy on 5V 2.4A playing BotW in portable mode, it still charges. It most likely charges quicker with a USB-C PD adapter though.
