Check out these cable reels from Designcord which have an auto-rewind function. Whenever you are done working with it, a simple press of a button retracts the extended cord automatically without any hassle. You don’t have to spend any energy or time rewinding the cord. In addition to that, the fixed socket design of this cable reel avoids any tangle of the plugged-in cables when the cord is being retracted. Watch the videos below for a demonstration.
