Scosche’s flatOUT LED ($20) is the second recent Lightning cable we’ve seen that uses a built-in LED to inform users if a iOS device is charging or fully charged. Unlike Just Mobile’s AluCable LED, which contains a small LED on the USB plug of the cable, flatOUT LED’s indicator is next to the Lightning plug side of the cable. A flat, tangle-free cable is another key part of the 3-foot flatOUT LED’s design.
