Meet the CoalBit: a mini power bank that charges your gadgets and also serves as a Bluetooth tracker. You will be able to use it to find your misplaced items and avoid leaving important things behind. The device also comes with a flashlight to get you unstuck.
The CoalBit lets you set up a distance alert between it and your mobile device. You can use the companion app to see the last known location of your valuable items. Yet another interesting Kickstarter project.
