There are many laptops now supports USB c charging.

I don't think you will find one without, unless they are in the lower end market.

Will a 100W GaN charger enough to charge one while using it?

Depend on the laptop. Most laptop supports 60 or 65 watts.

Learned something new today...didn't know there's a wattage limitation on laptop side

makes sense if not the laptop will be fried

Dell's proprietary laptop charger is 130W hor

dont think there is a "limitation". laptops and their chargers are quite smart nowadays, and if the charger is rated at 65w for eg, it wont be constantly supplying 65w. it will supply whatever the laptop require.

eg, laptop can draw up to 65w, but only require 35w now (maybe cos its already at 100%), charger will supply 35w.

if charger rated for 100w, laptop require 65w, it will draw 65w which charger will supply, instead of the 100w, as the 100w is only the max the charger can supply.


tldr, charger will supply what laptop requires. 100w charger paired with laptop that have max power draw of 65w will only supply 65w.

USB-C PD officially supports up to 100W.

Dell USB-C charger when used with the Dell laptop supports up to 135W, which is over PD spec. Of course depends on the amount of power the laptop is using, which in certain situations might be more than 135W, thus draining battery power even when plugged in.

must look at voltage requirements also
fyi thinkpads require the charger AND cable to accept 20V
a 30W charger can still replace a 45W laptop charger,albeit slower charging times

on a side note - i am selling a UK 3-pin plug Anker 30W GaN charger (can charger laptop as well)...too many usb-c chargers

yup! if the charger that comes with the laptop is not over 100w, it will most probably charge properly with a 100w third party charger.
