The major exception to this is the Nintendo Switch that, due to shit design on Nintendo's part, can asplode itself.
The only time things break is when you attach a broken charger that outputs 9 volts onto a wire that's supposed to be doing 2 volt signals.
The switch dock demands 39 watts, which implies 15 volts, but the switch itself will negotiate any voltage when standalone.
In fact, I am doing it right now.
Output on the adapter reads: 5v@1.5A/15v@2.6A
