Through November 16th, head over to Amazon where you can score this Xcentz Portable Charger for just $9.99 shipped when you use promo code WMHEYICY at checkout. Dual-port charging allows you to charge your phone and other devices at the same time. It’s the smallest battery charger I have ever used and it holds enough juice to power my iPhone 4 times. I bought this brick to use on the Inca Trail, where I would have 4 straight days of no power outlets to charge my phone and camera. It kept my phone charged the entire four days.
