Mi Air Charge Technology

Xiaomi’s Mi Air Charge technology, first unveiled in early 2021, represents a revolutionary leap from proximity-based charging (like Qi) to true remote wireless power. MiAlibaba However, as of mid-2026, the technology remains a concept/lab-stage prototype and has not been commercialized for the mass market. AlibabaIdropnews

Technical Breakdown

The system uses millimeter-wave (mmWave) beamforming to transmit energy through the air:

* Transmitter Station: A large unit containing 144 phased-array antennas that perform space positioning to locate devices and transmit directional mmWave beams (24–30 GHz). AlibabaMi

* Receiving Device: Requires a miniaturized antenna array (14 antennas) and a "beacon antenna" to broadcast its position. Mi

* Performance: It targets 5W remote charging per device within a radius of several meters, supporting multiple devices simultaneously. MiAlibaba

Product & Market Status (2026)

* Commercial Availability: There is no official release date. No production Xiaomi smartphones currently include the necessary receiver hardware, and the technology still faces significant regulatory hurdles regarding safety (mmWave exposure) and radio interference. Alibaba

* Market Trends: The broader wireless charging market is booming, projected to reach over $39 billion by 2033. SnsinsiderFortunebusinessinsights However, current commercial growth is dominated by Qi2 (magnetic) and long-distance inductive charging (35-50mm) used in furniture. Coherentmarketinsights

* Competitive Landscape: While Xiaomi focuses on consumer demos, competitors like Ossia (Cota) and Energous (WattUp) are successfully deploying similar RF-based remote power in specialized industrial and IoT sectors. Alibaba

Commercial Alternatives

While true "room-scale" air charging is not yet available, "Long Distance" wireless chargers (effective through 20-45mm of desk/furniture) are widely available for sourcing:
