Unfortunately, our batteries don't carry the same passion for cold weather as we do. They often tend to ditch you when you're just about to upload that killer picture of a double naked backflip in the off-piste. As a result people won't believe you cause you never uploaded the picture, and all you can do is blame your battery. Lame!But now those days are over. With this new power stick, you have no more excuses. You actually have to do the backflip, because you will always have enough power to show it off.
