Neutrik make a variant specifically created for power connections instead
of speaker connections. I think they are essentially the same style
design but with different color coding to make them stand out from speaker
connections. I don't know if the contact plating may be different, or the
spacing different so it can handle higher voltages. Ground mates first
before the two power pins (three pin instead of the four pin Speakon). UL
listed for up to 250V AC.

Most important, the power and speaker connectors are NOT intermateable.
The little tabs and notches are different.
In the movie biz, the 4 pin XLR is pretty standard for 12 and 24VDC
battery packs. It's been almost 20 years, so I don't remember the pinout.
The 3 pin XLR is a pretty good sized pin that can take a lot of current.
The 4 pin is smaller, and the 5 pin is really pretty small.
The XLR is nice and rugged (although not waterproof, it can be made so),
and it tolerates being driven over or stepped on, and it locks. The
chassis mount is fairly small (not much bigger than a Anderson PP with
chassis mount housing/bracketry)
