Question Is it possible to convert the DC input to a USB-C input?

[the_apprentice]

I have a laptop which uses a regular DC input and has a adapter of 19V and 3,42A. The battery inside is a 11,55V with 50Wh or 4335mAh/ min 4210mAh.

When I Travel I allways take my laptop with me and its hard to find a AC output on the plane or buses. Since everything is USB -C ,if you dont travel on long distance flights.

My questions is, is it possible to convert my DC input (the cable that goes inside my computer) to an USB-C input instead? Is it a task that requires a lot tests and analyses or is it possible to do it with the right sorts of tools ?

IF you have a USB PD source that can provide 20VDC -- here is a PDF on USB power -- https://www.ti.com/lit/wp/slyy109b/...61292&ref_url=https%3A%2F%2Fwww.google.com%2F
then you could use something like this -- https://www.newegg.com/jacobsparts-less-than-1-ft-usb-type-c-black/p/1VJ-00E4-00021
It really depends on the USB-C power source. Possible, yes. Guaranteed? NO.

I obviously travel on the wrong sort of planes and buses, because all I've ever seen is 5V USB-A sockets and half the time they're broken. I don't use my old 2018 HP laptop with 19V 3.5A power on public transport, but can usually get 8 to 10 hours use out of the battery in my newer (2021) laptop, without the need for an external power source.

I mean, technically anything is possible with a lot of tests, analysis, and the right sort of tools.

But if you're asking for a "[manufacturer] laptop charger to USB-C" adapter, no, those don't exist and no, you can't jury rig one. Chargers these days require communication between the device and the charger to safely deliver power, and you can bet laptop chargers aren't talking the same language as USB-PD.
