Faster and safer charging with our advanced technology. The Anker PowerLine is reinforced with bulletproof Kevlar fibre. That makes it much stronger than conventional cables. 10 times more durable, we bent this cable over 10000 times and saw no damage or change in performance. PowerLine Micro USB is the toughest cable you've ever seen. Thanks to wide diameter wires and reduced cord resistance, PowerLine enables the fastest possible charge speed via any USB charger. Superb fit to maximize case compatibility, we made the connector as compact as possible, without compromising its durability. We back them all with an 18 months warranty and provide friendly, easy-to-reach support.
