Here’s an interesting twist on the external battery pack, the ECO Booster. This pack can be used with virtually any phone that has a micro-USB connection, it attaches to the back of your phone and it even has a built-in stand. Supposedly it can double the battery life of most phones, and will cost only $34.99 at launch in October.

Concord Keystone Trading, a pioneer in smart phone charging solutions, today announced it will introduce its new Keystone ECO™ Booster portable battery pack for Micro USB smart phones, at IFA in Berlin (Hall 26 C Booth #826).
The portable Keystone ECO Booster charges and extends the battery power for smart phones and is the newest addition to the line of proven power performers from Concord Keystone, including AmigoCase, Solar/USB Power PAK and other charging units and accessories.
The Keystone ECO Booster has a built-in retractable Micro USB charging cable so no additional accessory is needed. The Booster has an adhesive gel pad hidden beneath a removable protective cover. After removing the protective cover, the Booster can be attached neatly to the back of the smart phone without slippage. The protective cover for the adhesive gel pad can be cleverly relocated to the back of the Booster to be used as a horizontal or vertical viewing stand while the phone is being charged.
The Keystone ECO Booster portable battery pack offers up to double the battery life for most Micro USB smart phones and is fitted with a battery check button & LED status indicator to show the charge level of the Booster.
