This version advertises 1000mah less than the other active deal, but adds a "cooling plate". seems to be in front of the fan blades. suggestion is skin contact. I can only imagine, imaginary gains in cooling, realistic losses in battery. I'll stick with the 5000mah for now.

I own with and with out the cooling plate. The cooling plate one does feel cooler no skin contact. I'm unsure how it works. But I imagine the cooling plate blows cooler than ambient air flow

The cooling plate is a Peltier plate. It does get cool but draws significant power. You don't need to touch the skin. It really does blow cooler air. I get 5 hr without and 2 hr with cooling on my 5000mah fan.

Wow I just got this thing and tested it with an infrared thermometer....it really does work. 71-75 without cooler / 55-60 with cooler (aimed it at the plastic part of the fan not the plate). Pretty impressed - bought the bigger one from a different brand too.

Just got a different brand one with a cooling plate about two weeks ago. I compared it side by side with the DivesBlue without the cooling plate.

The cooling plate does feel cold to the touch with skin. But after several side by side attempts, I can't say the blown air is any cooler.

The one with the cooling plate absolutely positively 100% does not blow cooler than the ambient air temperature.
