What does Qi stand for?

Qi, pronounced “chee,” is a Chinese concept commonly translated as “life energy.” It gave its name to the interoperability standard for wireless charging developed and maintained by the Wireless Power Consortium (WPC).

What is the Wireless Power Consortium (WPC)?

The Wireless Power Consortium (WPC) is the standards organization responsible for developing and managing the Qi standard. A Qi certification ensures the safety, reliability, interoperability, and power efficiency of a device. It also ensures that the product has undergone rigorous tests to meet these standards. Moreover, Qi certified devices work seamlessly with each other, regardless of their make or build version. Currently, the WPC boasts of more than 300 member companies, including the likes of tech giants such as Apple, Google, Samsung, Facebook and many more. Our subsidiary company, IBL-Lab GmbH, is also a proud member.

Why is Qi Certification important?

The Qi Certification serves as a quality feature of devices with wireless charging function. It ensures that the respective wireless devices function properly in terms of safety, interoperability, energy efficiency and user-friendliness through various rigorous testing procedures carried out in authorized test laboratories. Compatibility ensures that all certified devices from a wide range of manufacturers and countries of origin work together. Heat protection and foreign object detection are just two of a number of safety precautions included in the Qi standard. In addition, only Qi-certified products are allowed to carry the Qi logo.

Which devices support Qi and how do I know if my device is Qi certified?

Qi supports different power profiles: BPP at 5 W, EPP at up to 15 W and Qi2 25W at up to 25 W. Supported profiles depend on the transmitter, receiver and certified product design. Qi Certified products have passed the applicable WPC tests and may use the relevant Qi or Qi2 logo. The reliable way to verify certification is to check the official WPC product database and the product’s Qi ID.

Latest Qi Specification

Qi2 for Wireless Charging Devices

The wireless charging market continues to grow across mobile and consumer devices. The Wireless Power Consortium introduced the first Qi standard in 2010. The Extended Power Profile later increased charging power to 15 W. Qi2 followed in 2023 with the Magnetic Power Profile (MPP), and Qi2 25W, based on specification v2.2.1, launched in July 2025.

IBL-Lab has now upgraded its Qi test environment to specification version 2.3.1 and offers pre-compliance testing for the latest specification. The corresponding WPC audit for Qi 2.3.1 compliance testing is currently being prepared.

Official Qi2 Certification at Our Test Lab

Our subsidiary, IBL-Lab GmbH, has been involved in the WPC standards development process as an "Adopter Member" since 2024 and provides support on technical issues as an Authorized Test Lab (ATL). Our test laboratory operates a dedicated Qi2 test environment in close cooperation with nok9 and is one of the few laboratories worldwide to offer Qi2 certification.

If you want your product to become Qi2 Certified, the applicable testing and certification requirements of the WPC must be met. Contact us now to get all the necessary information.

Regulatory Wireless Power Transfer Testing

For products with wireless charging capability, like IoT devices, automotive infotainment and even household appliances, regulatory testing is the prerequisite for successful market approval.

For the European market, the following standards may apply under the RED (Radio Equipment Directive):

Radio Testing: DIN EN 303 417
Which tests of the standard have to be performed depends on whether the device is a transmitter (charger) or a receiver.
EMC Testing: DIN EN 301 489-1 and DIN EN 301 489-3
These tests include EMI (Electromagnetic Interference) and EMS (Electromagnetic Susceptibility).
Safety Testing: DIN EN 62368-1

For market approval in the USA, FCC 47 CFR Part 18 and/or Part 15 may apply depending on the device functionality.
