More and more contraptions that charge devices or generate power without needing an electrical outlet are hitting the market. Some, like the PULSE Kinetic Jump Rope, are in their prototype stages, while others like the Voltmaker are ready to be shipped off.
Granted, you’ll be able to get a bit of a workout with both devices. Voltmaker will have you turning its hand crank until your arms are sore, while PULSE will have you jump rope until you’re ready to collapse so you can charge up your phone.
The PULSE kinetic jump rope looks like your typical jump rope on the outside, but the built-in dynamos in the handle make all the difference. Every spin the rope makes generates power that is stored in the embedded rechargeable battery. You can then hook your phone up to the jump rope’s handle in order to charge it.
The PULSE jump rope is currently available in a limited beta test run. Only 100 of these have been made, and each one retails for $129(USD).
