Now through June 25th (or while supplies last), Staples is offering this Urge Basics PowerPro USB Keychain Charger for only $3.99 (Reg $39.99)! Plus you should be able to opt to pick it up in store for FREE. This recharges most USB powered devices with a 2,000mAh capacity.
These would be GREAT to add to your 72 hour kits in case of an emergency. Maybe even grab a couple so you can keep one in the car too!
