Smartphone charging technology company Concord Keystone Trading has announced the Keystone ECO Booster 2.0 – an ultra slim and lightweight 2000mAh portable battery pack for Micro USB smartphones.

The ECO Booster 2.0 has a built-in retractable Micro USB charging cable so it recharges the smart phones without the need to bring another loose cable. The unit can be attached to the back of the phone using the adhesive gel pad concealed beneath a removable protective cover, which can be relocated to the back of the Booster 2.0 to be used as a horizontal or vertical viewing stand while charging.

The battery pack typically offers up to double the battery life for most Micro-USB smartphones and is fitted with a battery check button & LED status indicator to show the charge level. The Booster can be recharged alone or with the phone together.

To broaden the usage of the ECO Booster 2.0, the package also includes an iPod/iPhone connector.

Keystone ECO Booster 2.0 will be available March 2012.
