QuickerTek power extender
QuickerTek has released an external battery that connects to the iPhone 3G, iPod touch, or any iPod with the 30-pin dock connector. The additional power can be used for 30 hours of music playback, six hours of video, or three hours of talk time, the company claims. A retractable USB charging cable is included with the package. The cable simultaneously charges both the external battery and the iPod/iPhone internal battery. The product is similar to the Richard Solo backup battery, but offers the additional iPod connectivity.
The QuickerTek external battery is now available from the manufacturer or dealers, and can be purchased for $45.
