While the convenience of wireless charging has revolutionized our daily lives, it hasn’t completely transformed them. However, that might soon change, as leading Chinese phone maker Infinix introduced a groundbreaking wireless charging technology at CES 2024 that can power your smart devices without requiring direct contact with the charger, thanks to their innovative AirCharge technology.
The company’s new over-the-air charging technology takes advantage of the low-frequency magnetic resonance to wirelessly transmit power, delivering up to 7.5W. This wireless charging capability extends over a distance of up to 20cm (7.87 inches) and for a single device, the power ranges between 1W and 5W when positioned within a distance of 10cm (3.94 inches) to 20cm.
As per the company, “The technology allows charging at a distance of 0-20 centimetres, and it even works when the transmitting coil and the receiving coil are tilted at an angle of up to 60 degrees. This remarkable capability is made possible by Infinix’s innovative multi-coil magnetic resonance technology and adaptive algorithms.”
As for device overheating, Infinix emphasizes that the AirCharge operates at a “safe low frequency” well below the limit of 6.78MHz, and delivers “reliable charging power of up to 7.5W.” It also features “an end-to-end Resonance and Over Voltage Protection (OVP) Circuit that effectively safeguards the circuitry, ensuring charging safety even in scenarios where the distance and position between the phone and the charging pad rapidly change.”
Infinix says that this feature will be perfect for users who prefer to keep their phones plugged in while gaming or video watching, as users will be able to simply install the wireless charging pad underneath their desks.

As of now, the company has not provided a timeline for the widespread release of AirCharge on a production device; however, the company plans to leverage this technology in the future, so it’ll be something worth keeping an eye out for.
During the reveal of the AirCharge, Liang Zhang, deputy general manager at Infinix, said, “What was once just a concept has now become a commercial reality. Infinix is committed to practicality and consumer safety as it pushes the boundaries of over-the-air charging technology. By focusing on multi-coil resonance technology and continuously making significant technological advancements, Infinix aims to revolutionize the way we charge our smart devices.”
In addition to the cutting-edge wireless charging technology, Infinix has collaborated with “industry-leading technology suppliers” to tackle the issue of lithium-ion freezing (which causes phone batteries to become inactive and unable to charge or discharge), faced by mobile phones in extremely cold environments. Infinix has introduced the Extreme-Temp Battery, which integrates “revolutionary biomimetic electrolyte and fusion solid-state technology on the electrodes.”
As per the company, “This breakthrough enables the Extreme-Temp Battery to perform exceptionally well even at temperatures as low as -40°C. With a charging temperature range of 100°C(-40°C-60°C), the Extreme-Temp Battery ensures functionality and endurance even in the harshest cold environments.”
Infinix has given no timeline for the release of either its AirCharge technology or its Extreme-Temp Battery technology. It also remains unclear whether we’ll ever see standalone versions of either a wireless charger or a phone equipped with both technologies.
