Wi-Charge uses infrared light to safely deliver power from a distance, Our award-winning products can charge a phone or power smart devices across the room, the enabling new and magical experiences. With Wi-Charge, new applications open for homes, offices, factories and public spaces.

Battery-powered devices are portable, but battery capacity limits functionality and frequently replacing batteries degrades the user experience. Moving wired devices, routing or hiding the power cords is a pain. Wi-Charge delivers 100x the power budget of battery solutions. With Wi-Charge, you can have the convenience of wire-free portability with a power budget approaching to a wired solution.

    Shipping to partners that integrate Wi-Charge components to enable the next-generation of smart devices.


 

 

OEMs welcome

Our wireless charging technology is ready for integration. If you no longer want to settle for the power budget of batteries or the need to be tethered to our power outlet, let’s talk. If you are building a smart home device, an industrial IoT sensor, a mobile phone or anything that could benefit from long-range wireless power, apply to become a beta partner.


How does it work?

Power is delivered using safe, focused, beams of invisible infrared light.

Transmitters connect to a standard power source and deliver power to nearby receivers.  Receivers use a miniature photovoltaic cell to convert transmitted light into electrical power.

Receivers can be embedded in mobile devices or connected into an existing charging port. The system is completely plug-and-play: transmitters automatically identify chargeable devices and deliver energy to them with pinpoint precision. Several devices can charge at the same time.

The following three diagrams illustrate this concept:

1. The transmitter searches for devices that need to be powered
 
2. Once a device is found, power is delivered using a narrow beam of safe infrared light. Users to not see or feel the energy beam.
 
3. If the light beam is broken, transmission stops, and resumes once the path is cleared.

 


Delivering Power Safely and Efficiently

Wi-Charge products are approved by the US FDA and also meet international safety standards.

Power is delivered using a straight, narrow beam. If the path between transmitter and receiver is blocked, transmission stops immediately. Once line of sight is restored, charging restarts quickly and automatically.

The beam delivered by Wi-Charge transmitters is focused on the receiver. This is both safe and efficient:

  • 100% of the transmitted power reaches the receiver. All the transmitted optical power can be used to generate electricity.
  • Power beams do not reach people, animals or unrelated objects.
