Introduction It seems like a great idea to have a small backup battery for your mobile devices these days. There are a ton of them on the market with various sizes and battery capacities. Some people also need extra storage – that 8GB iPhone fills up quick with songs, videos and pictures. What if you were to combine the two? Well our friends at RAVPower did just that. They combined a 3AH battery pack with a WiFi hub, SD card and USB storage. That’s a lot of features in a little package. How well does it work?
