QI certification

Wireless Power Consortium, founded in December 17, 2008, is a cooperative organization composed of several independent companies. The aim is to create and promote the widely used international charging standard Qi, which is compatible with all rechargeable electronic devices.
As of October 2017, WPC has 289 members from various segments of the domestic and foreign industries, including 289 brands, including apple, Samsung, Microsoft, LG electronics, PHILPS, NOKIA, SONY, Weili Valley VLG, Wisepower and so on, which have been included in the WPC alliance.

Introduction of the Alliance

The union of wireless charging is governed by the Charter of the union, which stipulates the aspects of confidentiality, intellectual property and decision making. The mission of the wireless charging alliance is to create and promote the widely used international charging standard Qi, which is compatible with all rechargeable electronic devices.
The alliance is managed by the steering committee, and each fixed member has one seat in each of them. The chairman of the steering committee is Menno Treffers. Technical specifications were set up by the specification working group, and the working group meeting was chaired by Chairman Scott Mollema. The promotion team is responsible for the communication between the alliance and the outside world. Its chairman is Camille Tang.

Alliance vision

Wirelessly create a good life
We love freedom. We like to walk and stop at any time. We enjoy the feeling that we don't need wiring, but can be connected at any time.
There are always a lot of inconveniences in connectors and wiring
Get rid of the last wire! Since everything is wireless, why do cell phones and small appliances still need to plug in wires?
Connectors and wiring are available
Transmission can be easily and simply short distance transmission without connector. Long distance transmission is still a bit of a challenge.
Battery charging is very common
Short distance transmission has been applied to various products, such as toothbrushes, LED candles, remote controllers, medical devices, electric tools, digital cameras and telephones.
A compatible charger is the trend of the times
We all love wireless products, but we don't want incompatible charging seats to fill our desks and houses. Our demand charger can be compatible with the products of different companies, and even compatible with the products listed next year.

Standard for wireless charging

The wireless charging alliance will set up international standards for compatible wireless charging seats. The compatible products will be printed on the mark for identification. The telephone, camera, remote controller and all mobile electronic products with logo will be compatible with all the charging seats with signs, simple and obvious.

International co-operation

The wireless charging alliance is a cooperation organization between Asia, Europe and the Americas. We believe that all mobile products in the world need compatibility.
The wireless charging alliance is a cooperative organization among different industries. We are convinced that all portable electronic products - mobile phones, audio and video players, computer accessories, cameras, remote controls, toys, games, medical and personal care equipment - will be printed on the mark of compatibility.
Open alliance
The wireless charging alliance accepts all applications of any company as members. All companies can use relevant standards and marks without distinction. We believe that this standard will be popularized in all products and markets.

Technical specifications

The charging time of the wireless charging standard will be equal to that of the existing wired charger technology, and is consistent with the main provisions and emission standards of the international radiation safety. The League will first set up international standards for devices under 5 watts and will then set international standards for high-power devices and equipment.


Short distance transmission is usually based on electromagnetic induction. With this technology, the receiver will transmit electricity only when it is near the transmitter. The discovery of magnetic induction technology can be traced back to more than 100 years ago. Because of its simplicity, efficiency and safety, it has been applied to various electronic devices for many years.

Alliance members

On September 2010, the world's first wireless charging Union, the world's first standard organization to promote wireless charging technology, announced in Beijing that the Qi wireless charging international standard was first introduced into China. The Ministry of information industry's electromagnetic compatibility (EMC) quality supervision and inspection center also joined the organization.
As of October 2017, the alliance has 289 member enterprises and is increasing. Including VLG, Atmel, Callpod, Case-Mate, Ren Bao, Continental Automotive, ConvenientPower, medium optoelectronic, Duracell, Yili magneto electric products Co., Ltd., strength (Energizer), yi Ke, Fulton Innovation, Hanrim Li Ming technology, music star cable, American National Semiconductor, NOKIA, Metrans, BASECOM, OLYMPUS, PHILPS, Powerkiss, extensor electronics, Rohm semiconductor group, RRC power solutions GmbH, Samsung Electronics, SANYO, sanfei, SixEye Interactive Ltd., Xinli Ericsson mobile communications company, ST- Ericsson, TI, Verizon, Wireless, Wisepower, Dongguang and Xentris Wireless company.
Wireless charging technology uses a unified industrial standard. In the next few years, hand-held phones, PMP/MP3 players, digital cameras, portable computers and other products all can use a new low energy, high compatibility of the same wireless charger. The charger is similar to a tray, which is directly plugged into the power supply, and the Alliance - certified "Qi" identifies the different brands of the different brands of the enterprise to be charged directly on it.
