About this deal
It won't "just work". USB chargers will provide 5V power unless there's some circuitry that will negotiate higher voltage.
Meter 5 volt USB to DC Power Cable - HDCabling 1 Meter 5 volt USB to DC Power Cable - HDCabling
USB 2.0 Power Cable for 1.3mm x 3.5mm 5v 2.1A 2100mA devices. This DC size (1.3 x 3.5mm) is usually found on tablets and low powered laptops (laptops that only require 5V power to charge). A perfect replacement for your lost charging lead. 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. 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. 5V is all that a PD charger will put out if the USB device being plugged in fails to communicate. It might put out 9V if it thinks there is a fast charging phone, but don't count on it. 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. Some laptops expect just a dumb power supply, others expect some simple communication or power select method. Since I own a USB-C PD 65W charger, I was wondering if it is possible to buy one of the various USB-C-to-DC-plug adapters and charge it that way?
