3 Απρ 2023 · If you were to design a self-powered USB hub, is there any sort of advantage to a 12V design instead of 5V? The logic being that if the source voltage were to drop a few volts (maybe 2-3V), a 12V regulator could still supply 5V, making the system less susceptible to failure if power were to fluctuate.
If something on the label reads "100-240v" or "110-220v" or something like that, it'll work. If, on the other hand, it reads something like "110v only", then it is not safe to plug into a 220v socket.

100w USB-C power supply with 12v input? Question. Hi all. I've got a Dell XPS 9500 which takes a Dell specific 130w USB-C power supply. They're clearly doing something sneaky and proprietary outside of the USB PD spec to get 130w over a USB-C cable.
An AC/DC adapter is made up of a central unit which draws power from an AC outlet, it then converts the power to DC that is used to charge the device. Each AC adapter has a specific power rating, measured in volts or watts that it can handle and the output of a device.
