"Lots of" laptops? Upon searching a bit harder I think the 16 inch macbook pro can probably do it. Most laptops that can hit 50% in half an hour don't have a big enough battery to charge at much over 60 watts.

Ebike is interesting.

The 16" MBP can charge at 140W over USB-C since the M3 (before that it's limited to 100W over USB-C, Magsafe was required to hit 140), the 14" can charge at 100W (specifically 96W) over USB-C: https://support.apple.com/en-us/102378

Framework's 16" can charge at 85W (1C on an 85W battery), and it can also pull 160W from the charger under load (possibly under load + charging).

Getting clear infos from Dell is impossible but it looks like a number of laptops are provided with 130W chargers, and their "ExpressCharge" is apparently a bit under 1C, so their 96Wh battery expresscharge laptops likely charge around 85W (and require 130W chargers to do so).

etc...

I don't see anything about charging at 140W on that apple page. I do see it saying 50 percent in half an hour which is a lot less. For the 16 inch that's near 100W, for the 14 inch with an almost 70Wh battery that's about 70 watts.

I guess 85W is enough to make a difference from 60W, but it's pretty close.

> and require 130W chargers to do so

Only if that's a weird artificial requirement, no way charging is only 60% efficient.
