CoreBook X 2021 Model Power Supply

Since there are only 2 ports, 1 USB-C and another USB-A, along with a barrel jack port for DC, is it possible to use a barrel jack port power supply to save the USB-C port?

If yes, please provide the tech spec for such a barrel jack power supply.

I received CoreBook X 2021 model and found out it comes with the barrel jack power supply, so I asked this question in error. The question should have been what’s the spec for the barrel jack power supply. The barrel has a smaller diameter than the ones I typically see.

Usually chuwi uses a 3.5x1.35 jack, but since there is no official manual, it is better to measure the jack if you are going to use a different charger.
The original charger has 65W, 19V, 3.42A output.
