AirCord™ Technology

Far-field wireless technology that has power, distance, and safety.

At Wi-Charge, we are making Nikola Tesla's dream of far-field wireless power transmissions a reality. While Tesla dreamed of beaming energy via large conductive coils, we found a more practical, efficient, and safer means of over-the-air power transmissions by using infrared beams. With more than 8 years of deep R&D, we've figured out how to harness the power of infrared to beam several watts of power at distances of 30 feet or more to thumb-sized receivers that can be embedded in all types of IoTs and other electronic devices. Furthermore, Wi-Charge transmitters support charging of multiple receivers, smartly dividing the total energy among charged devices.


AirCord™ delivers more usable power over distance than any other approach, enough to safely charge even a smartphone. This is thanks to a focused beam that transfers the energy directly from the transmitter to the receiver.


AirCord™ powers devices at room-sized distances and beyond. Power is the same regardless of distance, unlike other technologies whose power drops as a function of the distance squared.


AirCord™ is certified safe for consumers in all usage scenarios. Power is delivered only to the target device and does not bathe the environment with unwanted radiation.

AirCord in action

The demo video above demonstrates what the future of power looks like. For our partners, this future is present reality. Each Lego train in the video represents an electronic device that can be powered wirelessly, whether static or in motion.

It can be your smartphone or electric toothbrush at home, a digital display at the edge of a supermarket shelf, a vibration sensor on an industrial production floor, or a smart door lock in a hotel hallway. It can be anywhere you need to power devices at a distance, over the air, safely, and without user intervention.


How it works

Wireless Power Transmitter

  • Plugged to the mains (AC or DC) or track lighting 

  • Converts electricity into safe infrared beams

  • Automatically identifies client devices

  • Delivers infrared energy to client devices

Wireless Power Receiver

  • Plugged to or embedded in a client device

  • Receiver converts IR to electricity

  • Receiver charges an internal rechargeable battery or a super-capacitor which the client device uses

  • The receiver sends back client device telemetry including battery status, usage stats, billing info etc.

System Block Diagram

  • One or more devices are powered simultaneously

  • Power is distributed intelligently between client devices based on their needs

  • Data is collected from each device


Advanced Topologies

Wi-Commercial and public spaces are likely to use multiple transmitters to power many client devices in large halls. Supermarkets, production floors, shopping centers, and restaurants have tens of smart devices to power.

For these types of deployments, Wi-Charge offers a complete wireless power grid network solution.


Multiple Wi-Charge transmitters communicate through a cloud server, allocating power to the different devices based on their power requirements, battery level, power availability, customer-set priority level, and other considerations. Smart AI algorithms make sure all devices enjoy endless battery life.

The network owner has access to dashboards and a control interface to easily monitor and manage the wireless power service in one or many sites. Custom logic can be added to fit the customer's business intelligence (BI) and control requirements.
