Meet the Power Tube 3000: a smart power bank for your iPhone with an app for battery analysis. The device features Bluetooth technology, so you can use it as a selfie shutter or presentation controller. The companion app lets you know how much juice your battery has left. You get an alert when you are running low on battery. The smart alert function also means you will get alerted when you are about to leave your Power Tube behind.
This device not only charges your phone but lets you locate it from your phone. It can also be used to track your other valuable items (e.g. your suitcase). The Power Tube is portable and light. It is available on Kickstarter right now.
