Meet CoalBit: a tiny power bank that you can take with you everywhere you to go charge your phone. It also has a Bluetooth tracker, so you can use it to find your keys and other valuable items. CoalBit comes with a mini flashlight to get you unstuck.
CoalBit can be used to find your misplaced mobile device. You can set up a distance alert between your CoalBit and phone to avoid leaving important items behind. The product will ship in October.
