Lenovo ThinkPads used to do that, but you had to know the system.
T580 as an example:
- T is the series
- 5 indicates 1[5]" screen size
- 8 indicates the year 201[8]
- 0 doesn’t really mean anything
So a T490 would be 14" and from 2019.
Though, I’m unsure of their naming scheme for newer models like T14 or T15. I think the 14 or 15 just tells the screen size, and then they add a “Gen 2”, “Gen 3” etc. to indicate the age.
Does this mean the US doesn’t have powerbanks with e.g. 30000 mAh capacity?
