This week’s CES has already provided a potentially phone-saving piece of gadgetry, but it looks like there are a few more telephonic tricks up its ample sleeve.

The next time you run out of juice just as you’re calling for directions—or in the middle of any declarations of undying affection you may have coming your way—you can spin this doohickey around your finger and get a few minutes of power to finish things off in a suitable manner. Keep it in a desk drawer or a glove compartment, and you may never go flat again. So far it’s still a concept, but with a little luck we’ll have it in our pockets before too long.
