We have covered many ways iPhone users can go about charging their device. There are plenty of solar, hand crank, wind, and emergency chargers on the market. You can even charge your phone by walking. The PULSE kinetic jump rope takes it to another level. It harnesses kinetic energy when you play and converts it into electrical energy that can be used to charge small devices. Minutes of play can generate hours of play.
PULSE has specially made handles to maximize energy production. It is custom designed with 3D printing. The beta release will be very limited (only 100 models). The PULSE has been designed for areas of the world where electricity is very expensive. It is available for $129.[via]
