Notebook over USB-C load?

I'm sure that my notebook (HP Envy x360 ryzen) can be recharged via USB C (PD 3.0). The voltage of the power supply with HP plug is 19.5V with a power of 65W.

Do I have to pay attention when buying a USB C chargers also that exactly 19.5v is possible or does that recognize the electronics of the USB c chargers themselves and regulates that, so that I can take also up to 20 v?

The sense of charging via USB-C is standardization. Each device should be rechargeable with each USB-C power supply.

Therefore, you do not have to worry about the tension; the devices themselves act out.

Important are the amps. The should be the same, some devices like eg no Schnelladelgeräte.

The device draws only as much power as it needs, the current (ampere) can therefore be greater, only the voltage (19.5V) must necessarily match.

The classic power supply that may have different plugs depending on the manufacturer, it is clear that you should have a power supply equal voltage. When loading via usbc but it is then the question of whether this standardization ensures that then adjusts the required voltage, since you can also load cell phones with 5v on a usbc power supply 20v.

Thank you first for your answer.

In the product description of many usbc power supplies that have been seen are called combinations of voltage and current such as 15V / 3A, 20V / 2.25A. That's why I was not quite sure if the standard usbc different voltages or can deliver everything in between.
