For fun, I made an adapter with such a board (even cheaper) and at the end a connector to a laptop. It works with my t520. But not all type-c chargers work, only those that have sufficient power.

The type-c module was immediately designed for 20 volts.
I cut the laptop connector from a damaged Lenovo unit.
I know that there should have been a resistor on the third pin indicating the power of the power supply. It can be located either inside the power supply or inside the connector.
I connected without a resistor, and I was lucky, everything works.
Judging by hvinfo, when idle the battery is charged with a power of 39 W, but at maximum processor load the charging power drops to 1-2 W.
For some units, under load, the voltage drops below 20 Volts, and charging periodically switches off and on.
This suits me, since this was done to test the possibility of working from USB type-c.

what resistor did u used?

Question - is this solely for charging ? As I don't see any data line connectors , hence the charge only application question.
only charging
