By now we’re familiar with Mophie, the household name in on-the-go mobile phone charging peripherals. The brand expands on its portfolio with a very special release: the Space Pack. At first sight, the case is works similarly to the existing Juice Pack; it holds the same 1700 mAh battery, essentially doubling the existing battery life of the iPhone 5 and 5s. What’s more though, the Mophie Space Pack also includes its own built-in storage, increasing the capacity of the phone by either 16 or 32GB. Users can manage the data with the accompanying Space app, which syncs with your computer to manage larger files without calling for a data or Wi-Fi connection. A nifty utility for power users on-the-go, the Space Pack will be available for pre-order soon on the brand’s website, with prices starting at $149.95 USD.
