The One Year Smartphone Backup Battery (2400 mAh).

This is the smartphone battery that holds its charge for a full year, ensuring you always have backup power during an emergency. While power seeps out of most rechargeable batteries after only three months of inactivity, this 2400 mAh lithium-ion battery has a unique covered jack that seals in power, so even after a year on the shelf it remains 97% charged. It fully charges an iPhone or Android in under three hours and can charge a device 11/2 times before requiring a recharge itself. Smaller than a pack of gum, the device also incorporates an LED flashlight and emergency beacon. Recharges via USB/AC adapter in six hours. 3 3/4" L x 1 1/2" W x 1" D. (3 oz.)
