Winter is here with a vengeance, and you may be plagued with dry skin and static shocks as a result of the dry air the extreme cold brings. The VapOrb USB Ultrasonic Humidifier can moisten your air and reduce your discomfort. Best of all, it’s only 2″ in diameter, so you can take it with you to work or anywhere else you travel. You’ll just need a USB source of power, so even a backup battery should work. Just float the VapOrb in a glass of water for up to 6 hours of humidified air in your personal space. You can program it to run for 3 hours or six hours, and it has an automatic turn off when the water runs out. The VapOrb USB Ultrasonic Humidifier is $14.99 at ThinkGeek.
