Thinner than a No. 2 pencil, this is the world's thinnest backup laptop battery. At only 1/5" thin and weighing less than 1 1/2 lbs., the battery stores unobtrusively in a briefcase and provides supplemental power without adding bulk or heft to a laptop. The 13,200 mAH battery powers a laptop for up to 3 1/2 hours and doubles the battery performance of 12" laptops (or smaller). An OLED display shows the percentage of battery power remaining and you can select a voltage output between 16 and 20 1/2 volts. The battery backup provides supplemental power to other devices via a USB port that powers a smartphone for up to 48 hours, an iPad for 20 hours, or an iPod for up to 72 hours. Includes 10 adapters to accommodate all major laptop brands. Recharges in 2 1/2 hours. 8 1/2" x 11" x 1/5" H. (23 oz.)
