Sony Announces Slim External Batteries for Mobile Devices

Sony announced a new line of small, flat external batteries to provide extra juice for tablets and smartphones. These are company's first external batteries to use its thin "laminate" technology.

At 7,000 mAh, the most capacious model is promised to provide about three full charges to a typical smartphone. The battery weighs 198 grams and measures 130x70x13 mm—about the size of a typical smartphone, making the two easier to carry together.

Sony will also launch a slightly smaller model that holds 3500 mAh, as well as a number of smaller cylindrical 2000-mAh batteries. The 3500 mAh version is promised to charge a typical smartphone in about 130 minutes. Withstanding 500 reuses, such a battery can be recharged in about 8 hours by USB and 4 hours by electric socket.

In Japan, the round batteries will go on sale from Oct. 13 and the flat version, from Nov. 14, with prices ranging from $30 to $91. Global launches will follow.
