This new jump rope gadget called the E-rope has turned up at Yanko Design. To the naked eye, it looks rather strange, downright sanitary or dirty, but it will actually do something else — charge AA batteries.
Each handle of the E-Rope holds a pair of AA batteries that are charged by the motion of the rope spinning around. A LED on the concept shows when the batteries are fully charged.
The designer says 20 minutes of jumping will charge the batteries fully. On the other hand, plugging your rechargeables into a wall charger will get the same results without you cracking even the slightest of sweats. But if you’re like everyone else and want to “Go Green” give it a try – just make sure you use this for it’s intended purpose ONLY 😉
