USB Mini Fridge.

This refrigerator is just large enought to cool one soda can. Plugs into any USB port. Link -via the Presurfer

That’s kinda interesting. I wonder, if my already on the edge PSU could handle that…
Bloody stupid. While it’s there, the USB volatge output is supposed to be a LOW power source — it’s intended to run varied computer accessories. A soda can chiller is not in any way connected to computer function. This would much more sensibly be plugged into a wall (or cigarette lighter). It’s just asking for trouble by loading up the USB power load. How much is that new motherboard going to cost?
Printers, external hardrives, scanners, etc. etc. How is this going to be worse than those. Do you know how much stress it will put on the system?
A powered USB hub doesn’t even have to be plugged to your machine – Unless the fridge has thermal feedback (Bing! Your coke’s ready!), you don’t bother. I have a hub just for localized light sources and chargers already – This’d be fun, too. And that way you can use it independently of your computer – say, on a bedside table? If you don’t sleep with your computer. ;^)
I think I want it. I wonder if they make one that fits a bottle. Cuz I like my beer…I mean soda in a bottle.
I also found a coffe-machine that works via USB. Unfortunately, it only keeps the coffee warm, but doesn’t make it hot.
The maximum current draw allowed on a USB port is 0.5 amp. So this thing can draw a maximum of 2.5 watt (0.5 x 5)
I think your 500watt power supply can take it.
Also, it’s a tiny pelletier element, they are also used to cool some processors.
Also, this is a nice gimmick, the perfect Father’s day present for the unimaginative.
