Nomad Wallet

Like any good bifold, the Nomad Wallet carries roughly eight cards, a bunch of banknotes (up to 500 Euro size), even a couple of business cards. But unlike most it also carries along one iPhone 6S charge. A thin but surprisingly capacious lithium-ion battery in the wallet’s spine packs 2,400mAh, output via an Apple-sourced Lightning cable to your device whether it’s an iPhone or iPad. The battery itself recharges using a Micro USB input and boasts a 4 LED charge indicator and is encased in high crush strength aluminum for durability — though you’ll probably not want to sit on this one.

Grab one at Nomad ($100) or Amazon ($103)
