This product will work with other Qi products

Have the product tested by an independent test lab that is authorized to certify Qi compliance.

The WPC has added 12 new transmitter designs to the Qi specification since the release of version 1.0

Many more in the pipeline

Including a transmitter using magnetic resonance

Outside the eco system

Proprietary solutions have a hard time competing with a standard

The techology evolves

Interoperability remains

  • more than 100 members
  • global
  • all relevant industries

The WPC brings you a logo

The Eco System

The Qi specification is evolving

WPC members compete in every part of the supply chain

A new transmitter product does not pass all compliance tests?

But it is interoperable with all current and future Qi receivers?

Add this new transmitter design

to the Qi specification!

  • With magnetic alignment
  • Without magnetic alignment
  • Single coil transmitters
  • 2-coil transmitters
  • Coil array transmitters
  • Moving coil transmitters
  • USB-powered transmitters
  • Mains-powered transmitters

What does the logo mean?

Higher power levels

The Wireless Power Consortium is increasing power levels from 5 Watt to 120 Watt.

Qi on phone:

"this phone will work with all battery chargers that carry the logo"

Design freedom promotes competition

The initial draft of the extension to 30 Watt is available for review and comment by the members.

The WPC members compete in every part of the supply chain

  • ICs
  • transmitter designs
  • automotive integration
  • test and certification services

Qi on battery charger:

"this charger will work with all power receivers that carry the logo"

Access to patents promotes competition

Low entry hurdles

  • The specification is publicly available
  • Product certification by a independent test labs
  • WPC membership costs only 10,000.- Euro per year

Royalty-free patent licenses for low power receivers

The members will not charge royalties for patents that are essential for implementing low power receivers.

How does a product get the logo?

Patent licenses on RAND terms for transmitters and other receivers

The members have agreed to license their patents on reasonable and non-discriminatory terms and conditions. Although none of the member companies have announced detailed license terms yet, the members agree that RAND terms and conditions will be determined such that they promote adoption of the Qi standard and rapid growth of the market.

(*) This is an informal summary of the intellectual property rules of the consortium. The membership agreement (also called the Consortium Charter) has the details.

The Authorized Qi Test labs are:

Design freedom allows product differentiation

Design freedom allows tradeoff between cost, user experience, efficiency, design

CETECOM in Essen, Germany

DLS electronic systems in Wheeling IL, United States

National Technical Systems (NTS) in Culver City CA, United States

SGS Korea in Gunpo City, Korea

TÜV Rheinland in Korea

TÜV Rheinland in Taipei

UL in Japan

How does a test lab certify Qi compliance?

Design freedom leads to innovation and product differentiation

Test labs use the Qi specification

Design freedom allows products to target applications with special requirements:

  • automotive (avoiding interference with other wireless systems)
  • embedded (distance between coils can be increased up t0 40mm)
  • integrate with NFC (to combine payment systems with wireless charging)

It is not a product specification!

Qi is an interface specification

The Qi specifications set the minimum requirements that products must meet to make sure they are interoperable.

Minimize the rules needed to guarantee compatibility of all Qi transmitters and Qi receivers

Maximize design freedom for developers of transmitters and receivers
