Inventor Kevin Alan Tussy claims to have created an accessory for Google Glass that will increase its battery life by up to three times, according to a release by PR Newswire.

Tussy says: "Google Glass is an amazing leap forward and the development team deserves a tremendous amount of credit. There are so many great apps for Glass in the works, people are going to want to use it all the time. But you can't use it all the time because of battery life. I saw the need and solution as soon as the internal Glass battery died on me. I got to work and had the design for a battery-packed retainer strap in my patent attorney's hands that same night."

According to the offical website, the accessory - called PWRGlass - has forecasted specifications of a 2000mAh Lithium-Ion battery pack and can be charged via a mini-USB cable.

Google Glass itself is still in development and has only been made available to a handful of testers, one of whom is on Tussy's development team. Tussy has, however, released 3D renderings of the Google Glass accessory and claims the feedback has been extremely positive.

"It's clear that Glass users need this solution. We plan on taking pre-orders on our website as soon as we have a ship date. We are also exploring creating similar battery-packed retainer straps for other augmented reality headsets like the Recon Jet," he explained.

Meanwhile, Tussy added the development team was also experimenting with memory cards, to provide extended filming capability. The extra battery is something that will come in very handy on such occasions.

PWRGlass is patent-pending, so details surrounding pricing, modification, etc, are still to be released.
