Say hello to your iPhone's new best friend. The Mophie Juice Pack Helium ($80) doesn't just protect your iPhone 5 — it helps keep it charged, too. Thanks to an advanced 1500mAh, the Helium is the thinnest Juice Pack yet, coming in at 13% thinner than even prior Air models. Standard features like LED battery level indicators and a micro-USB charging port are carried over, as are battery pack benefits like up to six additional hours of talk time, six additional hours of browsing via LTE, and up to 30 extra hours of audio playback. Available in dark metallic and silver colorways.
