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 1 1/2 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.)
The One Year Smartphone Backup Battery comes with The Hammacher Schlemmer Lifetime Guarantee. If this product ever disappoints you, for any reason, you may return your Hammacher Schlemmer purchase for exchange, credit, or refund.
