There are a good amount of lower power ones (e.g. with an N100 CPU) that draw ~15W usually and not that much more at full bore, and some of them are starting to come with USB-PD power inputs (even if they come with a DC power adapter some will accept USB-PD on another port).

Look for "PD in" on this sheet for some examples (columns BW-BY): https://docs.google.com/spreadsheets/d/1SWqLJ6tGmYHzqGaa4RZs...
