Product Overview

Power Unplugged

Energous Corporation is the developer of WattUp®—an award-winning, wire-free charging technology that will transform the way consumers and industries charge and power electronic devices at home, in the office, in the car and beyond. WattUp is a revolutionary radio frequency (RF) based charging solution that delivers intelligent, scalable power via radio bands, similar to a Wi-Fi router. WattUp differs from older wireless charging systems in that it delivers power at a distance, to multiple devices – thus resulting in a wire-free experience that saves users from having to remember to plug in their devices.


True Mobility

Wire-free power delivers on the promise of true mobility and the freedom to roam where you want to without worrying about your battery powered devices running out of a charge. WattUp Mid Field and Far Field transmitters give you the freedom to receive wireless power within a charging zone without having to surrender your device to a pad or static location.

WattUp Receiver Devices

WattUp RF-based charging can be integrated to provide wire-free charging to a wide variety of electronic devices such as smartphones, tablets, fitness bands, smartwatches, wearables, cameras, wireless keyboards and mice, headsets, sensors, LED lights, remote controls and toys and many other battery-powered devices in your home, office and beyond.

Works Like Wi-Fi

A WattUp transmitter, or Power Router, sends energy via a Radio Frequency (RF) signal to your WattUp-enabled electronic devices when requested. A WattUp receiver in each device converts that signal into battery power. The entire system is software controlled, so it's intelligent and customizable to your needs and environment. And, because it's designed to work invisibly in the background, WattUp can make low battery anxiety a thing of the past.

How Does it Work?

A Radio Frequency (RF) system, similar to a Wi-Fi system, delivers safe wire-free charging energy at distances of up to approximately 15 feet from a transmitter to a receiver device.

The Hardware

Highly focused pockets of energy are delivered via multiple miniature antenna arrays and WattUp Transmitter technology in the transmitter. Capturing of the micro energy beams from these pockets then takes place via paired antenna arrays and WattUp® Receiver Technology in the receiver devices.

The Software

The WattUp® software system ensures that the charging waveforms are dynamically directed, focused and controlled via proprietary algorithms.

WattUp Technology at a Glance

Transmitter Icon


WattUp transmitters deliver on-demand wireless charging energy. The power and distance delivered are determined by the size of the transmitter and the number of Transmitters ASICS and antennas used in the design. The WattUp® technology is very scalable, providing wireless power and charging options to partners that vary from contact-based charging all the way up to 15-foot charging-at-a-distance, covering a total of 30-feet end-to-end.

Receiver Icon


WattUp® receivers use multiple miniature antennas to capture the micro energy beams sent from the transmitter. This smart antenna technology means power is delivered in safe, small, and focused amounts.

WattUp Software Icon


The entire WattUp® wire-free charging system is software controlled. Using either a mobile app or cloud-based web portal, you can identify which devices you want to receive power, in which order of priority, and even at what times you want the devices to charge.

You can prioritize charging mobile phones and tablets when you get home, while also having the flexibility of charging household devices including sensors, remote controls, keyboards and mice while you’re away. If you prefer a hands-off approach, WattUp® has the ability to automatically and intelligently manage all of your charging needs.
