Energous WattUp Wirelessly Charges Gadgets 3 Feet Away

This wireless charging tech, which they are calling Wireless Charging 2.0, can do both power-at-a-distance and contact wireless charging.

These ushers in a new era of wireless charging for devices like smartphones, tablets, smartwatches, fitness trackers, earbuds, smart speakers and more.

Inductive charging or wireless charging uses an electromagnetic field to transfer energy between two objects through electromagnetic induction.

The certification from the FCC was provided to Energous Corporation for it WattUp mid field transmitter.

The technology works by sending an RF signal to WattUp-enabled devices upon request.


Energous says it went through "rigorous, multi-month testing" to meet the FCC's safety and regulatory standards. Sure, it hasn't required us to plug-in our phone to charge, but it has required contact between two devices (one of which is plugged in) in order to push current.

Furthermore, the WattUp Mid-Field Transmitter has the ability to charge multiple devices (actually any number of devices) at the same time.

The product that Energous is going to be showcasing in the future is called WattUP and will not require you to place your device in a static position.

Wi-Charge's technology delivers up to 10W of power over 30 feet to multiple devices via an infrared light beam.

The intended device needs a special internal or external receiver for the WattUp transmitter to work, but apparently the receiver is small enough to fit into most phones, and it reportedly also works with waterproof devices. Similar to WiFi, the WattUp ecosystem ensures interoperability between receivers and transmitters, regardless of the manufacturer, making the entire ecosystem flexible and accessible for consumers and manufacturing partners. Other than Mid Field transmitters, they are also developing Far Field transmitters to cover extended spaces and low-power Near-field transmitters which could be embedded in devices like laptops, and monitors and charge connected peripherals.
