100W PowerBank or lower?

I have MacBook Pro 16" 2021 and I am looking for a decent power bank which will allow me to charge without sacrificing performance.

For obvious reasons I am not able to find anything which would support 140W power but I noticed there are a couple of options for 100W like the LinkOn Neutron 26800mAh - https://linkon.biz/en/product/751-linkon-neutron-136w-power-bank-26800mah.html

Does anyone tested the 2021 model with a 100W power bank? Any feedback before I make this investment?
