One thing that stays common between early adopters of Google Glass is its not-so-great battery life, but designer and inventor, Kevin Alan Tussy, has an idea that could triple the battery life of Google's wearable device.
His idea is called PWRGlass, which is an external battery pack that would be sold as an optional accessory to Glass. PWRGlass isn't anywhere near ready, with the only form it exists in right now is in a computer, as a 3D render. But, as it stands, it features a 2000mAh lithium-ion battery that is built into the sunglass band-like design.
There would be a microUSB connector on PWRGlass, that would allow a user to recharge both the PWRGlass, and Google Glass, at the same time. The designer is also working on a second device that would give Glass an injection of storage from its on-board 12GB.
