Crisis averted
Few things can induce the same amount of panic as looking down and seeing that your iPhone has only one bar of battery left and you're not near an outlet. Fortunately that's a feeling you can virtually eradicate with the Power Spring 4 external battery case for iPhone 4 from MiLi Power. This clever case will allow you to nearly double the battery life of your phone, so you won't have to worry about power-intensive apps like GPS trackers or lengthy calls. Unlike many battery cases, though, this one has a sleek design that looks great with your iPhone 4 and doesn't add much bulk, so you can still keep your phone in your pocket no problem. With the Power Spring 4 from MiLi, enjoy the freedom to choose when and where you charge your iPhone. One quick note, though: While it allows access to all buttons and both cameras, since it plugs into the dock connector, the Power Spring 4 must be taken off to use your iPod with the standard USB syncing cable and some accessories.
