The airflow was okay, for such a tiny little fan. It was definitely quieter than other fans of comparable shape and size. I only wish it moved more air.
The fan was able to stand up on its own, even at its highest setting. The only problem was, the entire thing would rotate, as the bottom was just plastic and had no way to grip any surface it was standing on.
There are two cooling, metal-looking plates. The shiny one at the front and behind that, one shaped the same as the protective, plastic frame. The shiny one got cold to the touch and was instantly covered in condensation. The other one never got cold to the touch or generated any condensation.
My laser thermometer confirmed all of this.
Without opening it up, I suspect that the 2nd metal plate, isn't even connected to the cooling chip.
Obviously, if it doesn't get cold, the air passing through it, cannot be cooled. As the shiny metal plate sits perpendicular to the airflow, it's most likely not helping to cool the air, either.
Honestly, with such wide gaps, I doubt it would have cooled the air anyways.
I also tested the fan out by aiming the fan at a couple different objects, with the cooling feature on, and then off. First, I ran it 5 minutes and then at 10 minutes.
Again, the thermometer registered no difference.
The shiny cooling plate does get cold and if you rub it against your skin, it feels nice and cool. But it's too small to noticably cool my skin or the blood flowing underneath.
However, the shiny plate did get covered in condensation, almost instantly.
Why doesn't somebody make a bottle (or cup or other shape) with one or more of these cooling plates to condense and gather water from the air?
Be great in a survival situation, especially if it had a solar panel and/or a hand crank (like emergency radios use) to power the cooling chip.
