Wireless charging is quite an amazing feat, being able to charge your devices without any wires is definitely a step forward from the traditional charging. A company named Energous Corporation has come up with its latest product, the WattUp, a Bluetooth and radio frequency-enabled transmitter that uses the same radio bands as a Wi-Fi router to deliver “intelligent, scalable power” to charge everything from smartphones and tablets to wireless keyboards and children’s toys.
Like a Wi-Fi router, the WattUp can be left in a room at home, plugged in, where it will be able to pump out power for devices to charge from. The router works up to 20-feet and sends the power in a mixture of RF (Radio Frequency), Bluetooth and other radio technologies. Potentially any device can use WattUp to charge as long as they have a small chip added to convert the signals to DC power.
This is a huge jump from power plates which are technically wireless but still require you to leave you phone in one place. With WattUp you’ll be able to move about with your phone in hand or pocket as it charges. Plates currently are 90 per cent efficient at power transfer and this technology will be 80 per cent efficient – That’s just one of many reasons Energous walked home with a Best of CES award in the Connected Home category as well as one for Disruptive Tech.

As per the test conducted, Wattup won’t be having 360 degree coverage with a 15 foot radius; instead the transmitter will create small 3D RF pockets that will cover a diameter of 4 inches around the device that is being charged.
Energous’ WattUp can charge devices faster the closer it is to the transmitter.
The wattage will be as what follows:
0 – 5 feet => 16W
5 – 10 feet => 8W
10 – 15 feet => 4W
The power transmitted will also be split among the devices being charged. For example, if there are 4 devices in the 0 – 5 feet range, each will be receiving 4W of power from the 16W output of the transmitter. Energous’ vision for the WattUp is to have it in the appliances we have inside our homes such as TVs or refrigerators.

The thing that matters is that, it won’t be available until 2016. Anyway it’s a good thing as it gives gadget manufacturers time to include the charging chips in phones and the like , so you don’t need to add that on.
Energous says it will begin licensing WattUp to both wearable and smartphone accessory markets, hoping the future bring expansive partnerships with Wi-Fi routers and smartphones themselves.
