I recently reviewed the MOS Spring Lightning Cable from Sewell, which had metal springs at the junctions between the cable and the Lightning and USB plug ends for extra strength at the most vulnerable points. I like that cable, and I’m continuing to use it with my iPad. I just saw the Titan MFi-Certified Lightning Cable, which takes the metal spring collars at the connectors to the extreme. The Titan cable is wrapped in two layers of flexible, high-strength steel; the plug ends have a sealed, one-piece housing fused directly over the cable for extra strength. The Titan is certified by Apple’s MFi program, so you’ll know the cable is safe for charging your expensive Apple devices. The 3.25′ Titan cable is built to last, and it’s backed by a limited lifetime warranty.
