There is a reason for USB-C extensions not to be part of the standard. They can be bothersome in the best case and dangerous in the worst.

    Interesting, I’d never trust any USB cable to push anywhere near 100 watts anyway haha good god, the most I ever do is maybe 20w at 5v.

    I’ll keep that in mind when buying cables in the future though this is very useful info!

      As a point of reference, Lenovo Thinkpad’s have something of a cult following for their reliability and versatility.

      My T490s has a USB-C power supply which provides 45w (20v at 2.25a).

      The thing is, when docked it’s not only pulling power through that cable, but also network, USB devices, and providing video for 2x monitors in 1920x1080. It’s kind of astonishing to me how much can be crammed in to one little connector. That said, it’s frustrating trying to find a usb cable that works reliably, because as you’d imagine not all USB-C cables support the same specs.

      My laptop can do 240W over USB-C, I’m just waiting for a charger that can do it with a modular cable

        It has a 240w charger but have you checked to see that it’s using all 240w?

        Most laptops use (up to) 120w.

          It can use almost all of it using the GPU

      If you buy a Steam Deck, or the Lenovo laptop I have for work, the only charging options you have are USB C. Their standard chargers put out at least 60 45 W, and they aren’t particularly special. In fact, I’m pretty sure 20 W at 5 V won’t be enough to supply these while in use, so you will either be using battery with long charge times in between, using them with battery-assisted power for longer use times until you hit those long charge times, or using the 60 45 W or more at whatever voltage the chargers provide.
