    Not usually, but all the time. It’s part of the USB standard to negotiate the power that the device and even the cable can handle.

      When all USB could do was 5V I already didn’t trust any charger but mine - I couldn’t believe people dared to connect their devices to charge into any public USB chargers.

      Now that they can go up to 20V, and we have to trust everything will work with the negotiation and wiring to get the right voltage, it’s even scarier!

        Will go up to 48V (240W) with the next USB-PD standard.

        But as long as it’s reputable hardware that actually implements the starndard, I’m not too worried.
