Don't take this comment too seriously, just a curiosity.
Powering capacity sometimes matters, but are there any devices out there where the charging speed would be meaningfully different? As in, they use significantly more than 60 watts to charge? (I looked up some of those super fast charging phones and they don't seem to be following the USB standards in the first place.)

Any device which can charge at 100W or more? Like lots of laptops, as well as my ebile batteries?

Soldering irons can benefit from being able to peak above 60W when heating.
They certainly can.
A dainty little USB-powered Pinecil v2 can peak at ~126W with appropriate firmware and an EPR 28v PD 3.1 power supply. It's an impressive feat. :) (And, yes, it requires a USB cable that is e-marked for 240W before this is allowed to happen.)
That said: 28v EPR is a bit usual. A more typical configuration runs on 20v USB PD at no more than ~64W, like a cheap, genuine [safe], used 65w Lenovo laptop charger cheerfully provides.
The question was about charging.
"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...
