What the Tethercell is essentially an adapter that draws its power from an AAA battery. Use it instead of an AA battery, connect it via Bluetooth to your smartphone and control your device. You can do all sorts of simple tasks starting from a simple switch on and off, setting timers for starting your device and shutting it down or to find out if the device is running on low battery. The device, as we’ve mentioned runs on AAA battery and when the phone or tablet communicates with Tethercell, power is cut off. You’ll need just one Tethercell per device.
