    Typically the PSUs are designed for minimum charging while the system is running and full charging when turned off. That implies if you want to charge via USB-C with the laptop running you'll need much closer to the full 45W, 18W wouldn't be enough. You might be able to charge using the 18W supply if the system were turned off, but it would be significantly slower than with the standard size.

    Good evening @MaClane
    I know these specs, but i didn't figure out that what is minimum power that the laptop need in order to charge itself... It just says 45W whats max whats min? Power banks usually have 9V and 12V options as mentioned in their specs but what is the amount of amperes it requires at minimum for charging it???
