Sony has announced a new external battery for the PlayStation Vita that supposedly adds an additional 6-10 hours of life to the handheld console. The battery's capacity will be 5000mAh which is more than double the Vita's internal battery of 2200mAh. Therefore, with both batteries you'll be able to get a whopping 9-15 hours of playtime out of your Vita with this accessory.
The external battery weighs 145g (about 5 ounces), its dimensions are 70x67x22mm and it will be released in Spring 2012. The price for the battery is still undecided, but, as it's a Sony product I'd bet anywhere between $50-70 is a safe bet.
Would you be willing to throw down an extra $50 bucks or so to get additional play time from your Vita, or are you going to stick with the standard internal battery that the console will come with?
