I have different work Thinkpads from 2019, so probably the first one was 2018 or 2017 generation. And they accepted whatever laptop usb charger (ok, most of them were also Lenovos, but some generic stuff our IT was ordering from Amazon as well)
My current T14 works with my AliExpress 120w powerbank.
Probably good to rely on brands who don’t mess with standards
