Compliance with the latest revision of the Qi spec

Manufacturers must make their products compliant with new versions of the Qi specification. The Logo License Agreement (clause 6) explains this rule and introduces the concept "Grace Period". A Grace Period is meant as a period of time which is available for manufacturers to make their products compliant to the revised specification.

The Logo License Agreement defines the Manufacturing Grace Period in clause 6.5. At the end of the manufacturing grace period it is no longer allowed to manufacture and sell products that were not tested against the latest version of the Qi specification. Note that products which have entered the distribution channels before the end of the manufacturing grace period may continue to be sold to consumers and need not be recalled.

Manufacturing Grace Periods

Manufacturing Grace Period for 1.1.2 Receivers

A version 1.1.2 receiver has the same Manufacturing Grace Period as a 1.2.0 receiver because the technical requirements for 1.2 receivers that implement the basic power profile have not changed between version 1.1.2 and 1.2.0.

Special Manufacturing Grace Period for automotive chargers for inline assembly

The Manufacturing Grace Period for "automotive chargers for inline assembly" will be the same as for other products, except that manufacturers can ask for an extension on specific charger models.

Special Manufacturing Grace Period for FDA-approved products

The Manufacturing Grace Period for products that require FDA approval in the US, or equivalent regulatory approval on other countries, is 10 years after the end of the registration grace period.

Unlimited Manufacturing Grace Period for automotive and furniture service parts

Service parts for automotive products and service parts for products manufactured as a fully integrated (non-interchangeable by the customer) part of furniture may be supplied for an unlimited period of time.

It is important to comply with the latest Qi specification

The Wireless Power Consortium revises the Qi specification on a regular basis. 

Qi specifications are numbered with three digits: X.Y.Z. For example 1.0.3

  • X is called the major revision number. Specifications with the same major revision number are backward and forward compatible.
  • Y is called the minor revision number. A change in minor revision number implies that new requirements are introduced while maintaining backward compatibility previously certified products
  • Z is called the editorial revision number. Editorial revisions include clarifications, integrate new transmitter designs into one document, and may add new test to the test specifications.

With each new minor revision, features were added to the specification that are important for product safety and for compatibility with future products.That's why we make it mandatory to comply with the latest minor version of the specification. More information about the differences between versions 1.0, 1.1 and 1.2 can be found on the specification page.

Editorial revisions of the specification don't introduce new product requirements. Products that are compliant with an older editorial update of the specification are therefore considered compliant with the latest editorial revision. For example, a product that is certified with version 1.2.2 is also compliant with version 1.2.3.
