Running low on power and desperately needing to send one last message or make one last call? The grab your keyring and look for the only key that can help you out in this situation: the bKey. It’s a small, white key-like device that gives your mobile device some much-needed power so you can do whatever it is you need to do before calling it a day.
Think of bKey as an emergency power source of sorts. Despite its small size, it can hold enough juice to keep your device powered up for an additional 30 minutes while you call, text, or surf the web.
