Nyko Power Grip for PlayStation Vita review
 

Gaming accessories come in all shapes and sizes --- replacement controllers, portable console suitcases, specialized mice, control augmenting nubs, you name it. Whatever your niche, you can bet there's a product out there to fill it. Nyko, in particular, has made a bit of a habit of fulfilling a particular need: manufacturing third-party battery accessories for all those short-lived handhelds. The outfit has such a solid track record in the category, in fact, that we had little doubt its PlayStation Vita Power Grip ($25) would live up to its life-giving hype -- but we decided to put it to the test all the same.
