Lightning cables are the lifelines for our most used mobile devices. Without them, we can’t charge or sync the data on our iPhones, iPads or iPods. And if you buy a wonky third party alternative, you’re often going to get a lot of buzzing and failed connections thrown into the mix. These ultra tough, MFi-Certified Lightning cables address all of the above. Worthy of any Apple device, they’re built to Tony Stark standards of toughness so that they’ll outlast the devices you connect them to. And right now, you can get a two pack of Toughlink MFi-Certified Metal Braided Lightning Cables for just $29.99 at Cult of Mac Deals.

This pair of cables marks an upgrade from the flimsy, easily torn white Lightning to USB cables that come standard with Apple devices. Their soft skins and plastic components are built to last for the day-to-day toughness we put our tech through. With MFi-Certification, they’re Apple approved to carry data and charge reliably. And their aluminum crush-proof plug design means a misstep won’t mean an unplanned trip to the Apple store. We live much of our lives through our devices, best to give them as long a life as possible.
