Using USB for power delivers frees people from incompatible connectors, but means that the use of splitters has become more widespread.
However, this introduces risks, as a device could negotiate a higher voltage via a splitter that is then sent to a device that isn’t able to handle it, causing it to turn into a smouldering wreck.
This is especially dangerous with USB-C / USB PD, as the cables can also carry audio, meaning that more devices are being used to transmit power and data simultaneously, increasing the use of splitters.
In order to prevent this from happening, you need to know how the internal wiring of a splitter or hub is set up.
This also brings up another problem, as many cheaper hubs and splitters do not have the capability to handle every possible scenario that they may be used for, meaning that it is still possible to accidentally send a high voltage to a device that cannot handle it.
Overall, although USB is a much more convenient option for power delivery, it is imperative to be vigilant about possible risks in order to prevent avoidable damage to devices.
