They suck and die all the time. It's a money grab upgrade like paint protection coating.

These aren't the same thing as a proper Peltier mechanism as you'd expect it to be implemented with a quality build. These are cheaply built evaporative coolers, not an industrial design.

I've deployed industrial units for outdoor enclosures that run on solar with no battery in places that get up to 115F during the day and do decrease the temp of an enclosure by 15-25F. They aren't cheap, but they do work better than those shitty things referenced in your link.

That's cool. Figured there had to be an industrial option which is always costly. So as soon as cost comes down for consumer grade that'll be nice.
