Build A Portable USB Air Conditioner From A Filtered Water Jug

Need cooling on the go? Instructables user imjasonc shows us how to build the most portable air conditioning unit we’ve seen, powered by USB and built in the case of a Brita water jug.

It uses the same principles as most other DIY air conditioners: place a fan over ice-cube-cooled water to blow freshly cooled air. A Brita jug is perfectly suited for this purpose, giving you a big reservoir for iced water and a small casing in the top (where you’d put the filter) for the fan.

The fan is powered by a USB cable, and it’s easy to pick up and take wherever you want to go (plus it’s easy to clean). Hit the link for the full how-to on wiring the electronics.
