USB Fridge

USB Fridge is the little desk gadget people mean when they want a tiny cooler for one can, a snack, or a novelty gift. By our assessment, its best trick is simple: it turns a USB plug into a bit of cold storage without taking up much room. The honest limit is just as simple, because USB power is tiny compared with a real fridge, so the cooling is mild and slow rather than proper food storage. In practice these things are more about keeping a drink pleasantly cool on a desk than about replacing anything in a kitchen. It sits in the same world as mug warmers and mini desktop gadgets, not full-size appliances, and it is for people who like the idea more than the serious function. It usually makes sense only when the expectation is very small from the start.
