Wireless charging hasn't really set the world on fire. Since the Palm Pre first introduced us to the idea at CES 2009, a few companies have added similar functionality to their phones and smartwatches. Power without wires is undoubtedly useful, but none of the solutions have ever set our devices free from a charging pad, which is tantamount to plugging them in, really. Energous is one of a handful of companies hoping to change that. It claims its technology can charge your phone and wearable from up to 15 feet away, no wires required.
Energous' system is called WattUp, and it works using a mix of RF, Bluetooth and a lot of patent-pending technology. The transmitter is where most of the magic happens. It communicates with and locates compatible devices using low-energy Bluetooth. Once they've established contact with a device, they send out focused RF signals on the same bands as WiFi that are then absorbed and converted into DC power by a tiny chip embedded in the device. These transmitters can be built into household appliances, TVs, speakers and standalone "energy routers."
