If You're Looking To Play Your Vita For Longer Than Five Hours Before Reaching A Plug, This Battery Add-On Should Keep You Going.

The battery has a capacity of 5000mAh, which when added to the 2200mAh already included on board with the Vita should provide enough juice to keep the system powered beyond short sessions.

A price has yet to be announced, but going by the cost of other PlayStation Vita peripherals we're guessing it won't be cheap.
