Tethercell turns AA batteries into Bluetooth devices (VIDEO).
What happens when you put a couple of SpaceX engineers together with some old-school batteries? You get a new-school approach to battery power. Tetherboard calls the Tethercell “the world’s first app-enabled smart battery.” Wait, don’t fall asleep, this is actually pretty cool.
A Tethercell battery is the size of a regular AA battery, but it holds an AAA battery inside its little case. It also holds a Bluetooth chip inside the case. Think of it as a battery turducken. This means you can use your smartphone to control the battery. Oh the power. You can turn off little Billy’s toy guitar when you want to take a nap. You can disable your spouse’s remote control when you can’t stand another second of mindless channel-flipping. You can even set hours when a device can be used.
