Our latest smart LED technology allows you to see your iPhone charge status at a glance. A custom circuit board with proprietary firmware communicates with your iPhone battery and displays a green or amber LED depending on your charge level. The amber light lets you know your iPhone is connected and charging while the green light means youve got a full charge. MFi-certified and featuring a universally compatible USB-A connector, you can charge up to 12W using a wall or car charger. Its an iPhone charging cable that keeps looking and performing like new, with an aircraft-grade aluminum overmold and double-braided nylon exterior that can withstand the wear and tear of daily use .
