I own a laptop that uses a standard DC power source and includes an adapter that provides 19V and 3.42A. The internal battery has a voltage of 11,55V and offers a capacity of 50Wh or approximately 4335mAh per minute. When traveling, it’s difficult to locate an AC outlet on planes or buses since everything is USB-C. If you don’t travel long distances by flight, your main concern is finding a USB-C port. My question is, can I change my DC input (the cable inside the computer) into a USB-C connection? Does this require extensive testing and analysis, or can it be achieved using suitable tools?

If you possess a USB PD source capable of delivering 20VDC, there is a PDF about USB power available here — https://www.ti.com/lit/wp/slyy109b/...61292&ref_url=https%3A%2F%2Fwww.google.com%. Another option is the product listed at https://www.newegg.com/jacobsparts-less-...00E4-00021. The suitability really depends on the specific USB-C power source. It might work, but it's not guaranteed.

I clearly take public transport that uses 5V USB-A outlets, though many are faulty. I rarely rely on my 2018 HP laptop with 19V 3.5A power, but I usually get 8 to 10 hours of battery life in my newer 2021 model without needing an external charger.

Technically, with sufficient testing, analysis, and appropriate equipment, almost anything is achievable. However, if you're seeking a "[manufacturer] laptop charger to USB-C" adapter, those don't exist and you can't just modify them. Modern chargers need communication between the device and the charger to deliver power safely, and laptop chargers likely don't support USB-PD protocols.
