I don't have an opinion about kw or w, but if the value is only a
number, then to prevent confusion and reduce mistagging the key should
specify, output-kw=22 .
OSM typically places unit after the value.

I'd vote for kW aswell (and a value of "22" then), since we're not
always using SI and not always base-unit-values (see kilometers per
hour).

Hello,
the OSM-Wiki-page on charging stations [1] defines the tag
socket:<type>:output=watt
wheres the examples contain values like "22 kW".
What would the preferred format be? "22000" or "22 kW"? I would
like to
clearify this on the wiki-page.
Personally I would prefer "22000" as it fits with other
OSM-values (no
units).
generally people are encouraged to add units for disambiguation
reasons and to use locally used units and preferably SI units.
For power, no default units are currently specified on this page:
https://wiki.openstreetmap.org/wiki/Map_Features/Units
And it doesn't even mention horsepower for power, a unit that for
many people may be more evocative than Watt (everybody can imagine
30 horses, but how much are 22 kW?) ;-)
Personally, if we were to set up a default for power units, I would
prefer kW, because if we'd use Watt we will get very high numbers
for MW (e.g. needed for power generators). Presuming, we would have
the same standard unit for all things power, and not different
defaults for socket and say power stations.
Cheers,
Martin
