This is great news. We won't have another gen of chargergate.
This seems like a weird omission, but will hopefully be fixed by launch - if not, I'll continue to use the Kid Icarus Uprising stand.
According to our source at Nintendo, as well as a source close to the production of the reveal trailer for the Switch, the hardware model shown in the reveal featured a USB-C port for power, situated in the centre of the bottom edge of the tablet. This port will be able to be used to charge the handheld while away from the Switch Dock.
Additionally, both sources have made it clear that the position of the USB-C port on the handheld means you will not be able to charge it while the system is propped up on its kickstand.
