Unlike other water purifiers, the SteriPEN Freedom “fits in your pocket and can purify a glass of water using just UV rays; simply stick it in your water, turn it on, and in under a minute it promises to have killed off 99% of bacteria.” Video after the break.

It even recharges via USB, making it extra convenient. Want one? You can snag it for $120 now.
