It says chills to 45f though. If its not true...

Right. I'm sure it's not that powerful, so it's probably only good for use indoors (like in an office or at home). If you're sitting out in the sun with it, I doubt it would make any difference because it would simply not be powerful enough.

Plus, it would probably help if the drink was in a metal can, since metal cans quickly transfer temperatures.
 
yea but it won't work inside either. the surrounding ambient air temperature would easily counteract any chilling effect that thing could possibly offer
 
Whoever said that this thing is just air cooled... Is that true or did you make it up? If it is true, you're not going to cool anything, at all. You can't cool something at room temperature with room temperature air. It has to be cooler... I don't understand. It may help you cool off a mug of hot chocolate quicker though.

Well, 45 degrees F is almost freezing, so let's say it is roughly equivallent to the temperature of an already chilled can of beer. If you put a warm can of beer directly in contact with a chilled can of beer, the temperatures over time will even out and then gradually increase to the environment's temperature. Unfortunately, the chilled can of beer is not a constant source of cold, since nothing is keeping it cold. Eventually it will warm up.

With the chilling plate kept at 45 degrees F, constantly, it is plausible that in an average comfortable human environment (between 70-75 degrees F), the plate will eventually cool the beer down and maintain it at a temperature level at least cooler than it originally was.

no, it's not plausible.

a) there's more at work than just simple heat transfer. some sort of convection current inside the can would be needed. you can't just cool the very bottom of a beer an expect the whole thing to cool off.

b)in order for this heat transfer to even occur in the first place, the can would have to be in contact with tht echilling device. the ring around the bottom of an alluminum can is no where near enough surface area to cause any sort of meaningful temperature change

b) if you put a warm beer directly in contact with a cold beer heat is not going to just transfer through where they touch. air around the cans will have a dramatic effect on the cans' temperatures.

again, it's just not plausible for this device to work.

you'd probably have better results if you took a **** on it.
 
PP, Just use the reusable icecubes, the ones in the little plastic thingies, there, no watering down!

And yes, its air cooled, theres a heatsink attached to a fan which keeps that coldplate chilled.
