Yeah, but that only works when your device uses less than 100W, because that’s what USB-C is currently rated for. Gaming laptops can easily use two or three times that amount while simply idling on the desktop. Once you start looking at GPU/CPU power requirements and active cooling, the power consumption quickly stacks up.
These devices usually have IEC power bricks with a fat barrel connector, because that’s what they require to be able to get enough wattage into the device. Requiring them to charge via USB-C is going to have them using two or three USB-C ports just to break even and avoid losing power. The power adapter would look like some weird fan-out adapter with one IEC power cable going in and three or four USB-C cables on the other end.
I’m laughing at the idea of a device having three or four USB-C ports, and not being able to use any of them for anything except charging.
USB-C has already standardized 240W charging. Apple already ships a 140W brick with their laptops since like a year or two ago, and Framework is shipping a 180W brick later this year.
Okay but that doesn't change the fact that many laptops have a USB-C port for charging now.
Of course, we've now learned that OP meant something a lot dumber about using phone chargers for laptops but this is a whole other imaginary situation OP has going on in their head.
