Your iPhone can help you find your way around in your city and outdoors in general. Many folks rely on apps and maps on their smartphones to find their way around. Things get a bit more complicated when you don’t have a reliable Internet connection. That’s why I like the idea of TopoCharger. This is an iPhone battery case that works off-the-grid. It has built-in offline maps, so you don’t need cell and data signals to view them.
Users can still rely on the GPS chip built into their phone to find their way around with the help of TopCharger’s companion app (Trimble Outdoors Navigator). They get information on more than 167.2 million land plots in 39 states. This could be a life saver for some folks. It will ship for $149 starting March 2014.
