Quick Summary A new camera battery called the iPower X has built-in tracking technology that lets you locate it when it goes missing. The iPower X is a rechargeable camera battery with a built-in GPS module and Bluetooth connectivity. That's important for camera gear, where even a small accessory can become annoying when you're trying to keep a compact setup. That makes the idea more useful than a generic tracker designed for your keys or wallet. Still, putting the tracker inside the thing you're trying not to lose is a very sensible idea.
