The Kanex GoPower Plus Batter Space portable battery. What I like about it is that it has a built-in charging cable. The main cable is a microUSB cable for Android users. But it comes with a Lightning adapter that slips over that microUSB plug, and both just tuck away in the body of the battery. It comes in Space Gray or Gold and has a capacity of 8,000mAh. It’s $59.95.
