It depends entirely on what the PD charger can put out, how intelligent the adaptor is to be able to select the right output from the PD charger and how tolerant the laptop is of "random" adaptors. as real users, posing a threat to a site’s security, so the site sometimes runs random security checks. This also assumes there's no communication or handshaking done between the laptop and the power source - a lot of the time this is done on the 3rd pin on a normal barrel style jack, so OP might have to make provisions for this also (in some cases it's as simple as putting a resistance between vcc/gnd and the 3rd comms pin. piece of plastic between your charger and your laptop and just how much faith you have in the old adage "you get what you paid for". I own a Acer laptop from 2017, which came with a brick-sized 19V/3,42A power supply that's connected via a 5.

If you want to use your USB C charger with confidence then you need a laptop that supports USB C charging.This cable is used if a 2 pin 220 Volt to 5 Volt DC power adapter can not be installed then plug this cable into the nearest USB source (HDTV, Projector, Blu-Ray, Xbox etc) to provide power to the 5 Volt Device. Please check to ensure this is correct for your device before you make your purchase as the DC plug size (this includes the inner pin) may vary. Some laptops expect just a dumb power supply, others expect some simple communication or power select method.

A laptop expecting 12V might not like receiving 15 or 20 from an adaptor that is configured wrongly, or simply might not work if the adaptor fails to negotiate with the PD charger and received only 5V. I'm quite sure that requesting 20V from a USB-PD compatible charger would work fine to power that laptop and within its design tolerances, but I'm not aware of such a product. USB chargers will provide 5V power unless there's some circuitry that will negotiate higher voltage. The technical storage or access is strictly necessary for the legitimate purpose of enabling the use of a specific service explicitly requested by the subscriber or user, or for the sole purpose of carrying out the transmission of a communication over an electronic communications network. This USB Power Cable is used to provide external power for HDMI Equipment, Switches, Extenders, HDMI Splitters, Network Switches, Routers, Access Points or any type of 5 volt device up to 2 Amps.
A tiny microcontroller could in theory talk to the PD charger to select 12V, 15V or 20V if available, so maybe an intelligent adaptor that knows what the laptop expects could work.
