This is Zsmart's patent pending electrical extension cord with manual and Bluetooth® wireless technology control. The Bluetooth wireless range of 30 feet or more, depending on environment. Does not require line of site. This is an inexpensive way to control on/off power via Bluetooth from a variety of devices. We like using these to turn on and off hard-to-reach projects high up or put inside structures without easy access. Since it uses an almost universal way of accessing it (A2DP Bluetooth) there are a lot of projects possible.
