If you've ever retracted an automatic extension cord you know that by the time the plug reaches you it's travelling faster than a bullwhip. Not so with the RoboReel, which gently and safely retracts the cable with an electric motor.
Inside the oil, gas and chemical resistant plastic sphere is 15m of heavy 12-gauge electrical extension cord that can be retracted at the push of a button. The RoboReel is also rather intelligent, preventing the cord from being rewound when current is being drawn or a tool is being used, and automatically cutting off the power if the cable has been accidentally cut. It's impressively high-tech, but how else can its creators justify its obscene $US390 price tag?
