I have a laptop motherboard I want to fix (need to solder over a few legs of a connector).

I do not want to power it straight from the power adapter/battery after soldering, in case I cause a short somewhere.

The power adapter is this one:

Would it be enough to just get a USB C cable, that can support enough Watts, strip it open, connect the ground and positive to the power supply, set the voltage, limit the current and connect it to the motherboard, a.la

According to the datasheet, there's a BQ25700ARSNR charge controller on the motherboard.
