NomadClip
Forget toting a cable in your pocket, or worse yet, a bag — with the NomadClip, you'll always have a charging cable with you. How, you ask? Well, the clip is actually a carabiner, with ends that fold out to reveal a male USB 2.0 plug and a either a Lightning or Micro USB plug. It's also built from high-end materials like engineering-grade polycarbonate from Bayer, high-grade steel, and scratch-resistant metal on the contacts. But while it will safely hang from a belt loop or keychain, we wouldn't recommend using it for climbing — after all, where are you going to find a charging station in the wilderness?
