The One Year Smartphone Backup Battery (8400 mAh)
4.9 (11 Reviews) ItemProduct Story
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 8400 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 iPad Mini, iPhone, or Android in under three hours and can charge an iPhone 5 1/4X before requiring a recharge itself. Includes microSD cable for USB 2.0 (Apple Lightning cable not included). The device also incorporates an LED flashlight and emergency beacon. Recharges via your device’s USB/AC adapter in six hours. 4" L x 2" W x 1" D. (7 oz.)
