> My laptop (bought this year) charges via a DC barrel jack, afaik because USB-C doesn't deliver enough power for peak usage

I've got a Dell 120W USB-C charger from a 2017 Dell laptop, and I think you can go up to 240W now.

Now the highest power is a bit of a compatibility nightmare. I also have a 60W framework charger but it will only charge the Dell at 15W because that's the maximum mode that both the Dell and Framework charger support in common.

But given the barrel connectors are usually only compatible with the exact laptop they're sold with, that's probably an improvement.
