Maxic Technology has become one of the first companies globally to obtain Qi2.2.1 certification
On June 16, 2025, the Wireless Power Consortium (WPC) officially launched the Qi2.2.1 standard. Recently, WPC announced the first batch of certified PTx products. Maxic’s MT201 module secured a place on the list, demonstrating the company’s leadership in core wireless charging technologies and its commitment to advancing new industry standards.
WPC introduced the Qi2.2 standard in 2024, increasing wireless charging power to 25W. It greatly enhances energy efficiency and thermal management while retaining Qi2’s magnetic alignment mechanism and is designed for high-power mobile devices, with backward compatibility of Qi2.0 and Qi1 standards.
Maxic's independently developed wireless charging transmitter module MT201, with 25W output power, has obtained the latest Qi2.2.1 certification (Qi ID: 24250). With Maxic’s wireless charging transmitter MT5820, which can charge multiple devices simultaneously, the module supports BPP (5W), EPP (15W), and MPP (25W).
Introduction of MT5820
MT201 is compatible with mainstream adapters by supporting a wide range of input voltages like 5V/3A, 9V/3A, and 15V/3A. It delivers a peak output of 25W, and uses dynamic power regulation technology to meet high-power charging needs precisely. With 56.53mm in diameter and 8.0mm thickness, its lightweight design offers strong structural integrity and excellent space efficiency, ideal for seamless integration into portable chargers and desktop docks. A built-in high-permeability magnetic core array provides 950gf of stable magnetic force. The Qi-standard alignment ensures close coupling during charging, reducing power loss from misalignment and maintaining a stable power link.
MT5820, a high-power and highly integrated wireless charging transmitter embedded in the MT201 module, adopts advanced magnetic induction technology and fully complies with the latest WPC Qi2.2 standard. It supports BPP, EPP, and MPP modes (5W/15W/25W), delivering up to 100W of total output power when charging multiple devices simultaneously.
