48V and we’re back to POTS (plain old telephone system) voltages :-)
I agree, but that’s the problem even from reputable sources, glitch happens. Old 5V-only chargers would need much more things to go wrong to fry our devices. A 20V (or 48V !) one is just a small (sw or hw) glitch away to zap a device that doesn’t support such voltages.
The USB standard is usally really robust and the changes of SW errors is small. If you have a good brand laptop it will probably come with very reliable charger as well. I really don’t worry about it.
