The Premium Heavy-Duty Charging Cable. PowerLine+ may be the last cable you'll ever need. Proven to last at least 5 times as long as other cables, it boasts a bend tolerance 10 times higher. There's simply no other cable with this level of durability. Exceptional tensile strength is provided by a fiber core, double nylon-braiding and precision laser welding. PowerLine+ is built to withstand any yanking, twisting, stretching, or dropping that it might possibly be subjected to. Wind up PowerLine+ and bind it using the adjustable velcro strap for easy transport and storage. It also allows convenient cable length adjustment to avoid trailing cables across the floor when charging. Low quality charging cables can reduce charging speeds by over 40%. PowerLine+ is designed with a thick wire gauge which reduces resistance and ensures maximum charging speed. At Anker, we believe in our products. That's why we back them all with an 18-month warranty and provide friendly, easy-to-reach support.
