MacBook owners have either heard or been victims of the horror stories that befall the fragile yet necessary chargers. With their two prongs for winding the cable for storage, it seems like the perfect design, yet time after time the cable becomes frayed. The team at JuiceBoxx have come up with a snap-on case for the MacBook charger that fits snugly around it and provides enough extra width to keep the charger cable from breaking its insulation and fraying. While the solution is very low-tech, it does aim to solve a problem that can be several times more expensive to replace. MacBook owners living in fear of damaging their chargers can have a JuiceBoxx in one of four colors for $20 by November 2014.
