Keystone has rolled out its new ECO AmigoCase for the iPhone 4. Designed like a portable phone charging station, the AmigoCase consists of a protective cover for the iPhone and a battery pack, which features a built-in clip to let users attach it to clothing or a bag, slipping the phone back into the pack when not in use, while keeping it protected when it is in use.
Features include an on/off switch for the battery pack, protection for the iPhone 4’s case when it is inside the battery pack, a 5500mAh rechargeable battery with a four LED charging indicator and micro-USB charging port, and open access to all ports and controls when the protective cover is used alone. Keystone’s new ECO AmigoCase for the iPhone 4 will be available in several different colors this Spring and will sell for $80.
