Frequently Asked Questions

  • In simple terms, a WattUp transmitter sends contained energy via radio waves to paired devices containing complementary WattUp receivers. The receivers convert those radio waves into DC power, which in turn charges the receiver’s battery.

  • Yes.

    The RF energy exposure with our technology is essentially zero when devices are not being charged. When devices are being charged, RF exposure is always below, and usually substantially lower than FDA, FCC and International limits.

  • WattUp® Mid Field and Far Field Transmitters sense and communicate to authorized receiver devices via Bluetooth Low Energy (BLE), and only send power when needed and requested by those devices. WattUp is software-controlled, intelligently determining which devices receive power, when and in what priority. If there are no authorized devices within range, the WattUp transmitter becomes idle, and no power is wasted.

  • No.

    WattUp transmitters only send power when receiver devices are present and need a charge. 

  • Initially, WattUp is targeted at electronic devices which typically require 15W and below:

    • Smartphones, Phablets, eReaders and Small Tablets
    • Wearable Fitness Trackers
    • Smartwatches and other Wearable Computing Devices
    • Computer Accessories, such as Wireless Keyboards and Mice
    • Remote Controls
    • Hearing Aids and PSADs
    • Home, Office and Commercial Wireless Sensors
    • Gaming Controllers
    • LED Lighting
    • Battery-Powered Children’s Toys
    • Drones
    • Security Cameras
    • CO2 sensors
    • Motion Detectors
  • Energous Corporation is taking a multifaceted approach to building a worldwide infrastructure for WattUp wireless charging.

    Energous is partnering with Original Design Manufacturers (ODMs), Original Equipment Makers (OEMs) and Integrated Device Manufacturers (IDMs) that currently design and manufacture existing wireless products (e.g. Wi-Fi).

    We are engaging key infrastructure providers and operators that have historically monetized new wireless technologies as they deliver them to the market (e.g. paid Wi-Fi zones).

    We are working with multiple receiver product design and manufacturing companies in the target segments listed above, and standards bodies, such as AirFuel Alliance, to roll out the adoption of compatible consumer electronic products.

    We are actively seeking target destination partners for wireless power to proliferate commercial location demand (e.g. coffee shops, restaurants, high traffic metro areas, malls, and airports).

  • As a systems company, Energous develops silicon-based wireless power transfer (WPT) technologies and customizable reference designs, which include innovative silicon chips, antennas and software, for a large variety of applications. It leverages its strategic partnerships to expand the WattUp ecosystem.

    A partnership with, and license from, Energous may include proprietary chip technology and design libraries, scalable transmitter and receiver reference designs, software stacks from device firmware to cloud-based enterprise management tools, high volume technology transfer readiness documentation, custom design and applications engineering support, as well as patent, knowhow and comprehensive intellectual property coverage.

    Through membership in the AirFuel Alliance, partners will be able to test and obtain interoperability certification to the uncoupled specification.

  • By contacting Energous, companies can engage in partnerships, either through Joint Development Agreements (JDAs) or other forms of agreements and licensing contracts. Partners will receive the support of our broad team of business professionals, and product design and deployment staff. Our team, with over 1000 combined man-years in technology development and commercialization, has been deploying and debugging WattUp technology from end-to-end (silicon to system, hardware to software).  Reference designs are not only developed to take advantage of the optimization gained from this depth of experience but are also created with economic and regulatory issues front and center. In short, your success is our success, and we will go the extra mile to ensure it!

  • 10cm is the recommended and standard test distance for “typical desktop applications,” per FCC guidelines for RF devices.

  • Yes, you can charge multiple devices on the same pad, depending on the available space on the pad.

  • No, WattUp will not interfere with Bluetooth or Wi-Fi, as we use different bands.

  • The mobile app is not required, but it does allow for more control over charging permissions, settings and other options.

  • WattUp has many benefits over coil-based wireless charging solutions found on the market today. WattUp provides an ecosystem of both at-contact and over-the-air wireless charging with its RF-based technology, while solving the orientation, placement and interference issues that consumers experience with coil-based solutions, as well as a variety of other pain points for manufacturers. The technology eliminates thermal challenges, foreign object detection issues, and it is a scalable technology with a smaller footprint so it can be integrated into a variety of sized devices, including the smallest hearing aid, which means easier manufacturing and lower BOM costs.
