Wireless Charging Motherboard PCBA Guide (Qi2.2, 25W, MPP)

The market for wireless charging motherboards (PCBA) is undergoing a significant transition in 2026, driven by the adoption of the Qi2.2 standard and the expansion into high-power applications.

Key Market Trends & Insights (2026)

* Qi2.2 Standard Dominance: The Qi2.2 certification is the new benchmark, increasing power delivery to 25W (up from 15W) and mandating the Magnetic Power Profile (MPP) for perfect alignment, which reduces heat and waste. Zeehoox Elecdov

* Infrastructure Growth: Beyond phones, wireless charging is being integrated into smart furniture, EV roads, and autonomous robots. Multi-device charging stations (3-in-1) now account for 34% of accessory sales. Zeehoox Elecdov

* Long-Distance Power: Technologies for room-scale charging (3W–5W over 3–10 meters) are gaining FCC approval for commercial use. Zeehoox

Technical Motherboard (PCBA) Design Insights
