Important News | Hongbiao has officially passed the Qi 2.3.1 laboratory audit and has become the first ATL laboratory to obtain the Qi 2.3.1 certification!

 

Recently, Shenzhen Hongbiao Certification and Testing Co., Ltd. (HONGBIAO) has officially passed the Qi 2.3.1 laboratory audit and became the first ATL (WPC authorized testing laboratory) to obtain the Qi 2.3.1 testing capability recognition.

This means that Hongbiao has once again upgraded its technical capabilities, laboratory system, and project service capabilities in the field of Qi wireless charging certification. This is not only an upgrade of laboratory capabilities, but also represents that Hongbiao continues to stand at the forefront of wireless charging technology and certification service development.

 

 

Authorization Qualification: WPC Authorized Testing Laboratory (ATL)

Certificate Number: 086027.17CE - Authorization Date: 2026-09-08

Scope of Authorization: Qi 2.3.1: BPP / EPP / MPP25 Protocol Conformance Testing (Power Transmitter)

Officially Available for Search: Hongbiao has been included in the WPC official authorized testing laboratory list.

01 From Qi to Qi2, we have always been at the forefront of wireless charging certification.

Wireless charging technology is developing rapidly. From the early Qi standard, to Qi2, and to the continuously upgraded technical specifications, product power, interoperability, magnetic suction experience, safety, and consistency requirements are all constantly improving.

At the same time, the product development pace of brand owners, manufacturers, and solution companies is also getting faster.

These issues pose higher requirements for the laboratory:

How to complete product verification faster?

How to reduce the risk of rectification during the certification process?

How to shorten the time for products to enter the market?

Hongbiao has been focusing on Qi wireless charging certification testing services for a long time and has continuously invested in personnel, equipment, and technical capability building. From standard upgrades, laboratory capability building, to the introduction of new version testing capabilities, we always hope to achieve: to provide customers with a more professional, stable, and efficient certification partner when new technologies and new standards arrive.

 

02 Qi 2.3.1 ATL Capability Officially Launched

With the successful completion of this laboratory audit, Hongbiao‘s Qi testing capability has been further upgraded. Currently, we can provide customers with relevant ATL testing and certification support services for Qi 2.3.1.

The authorized Qi Compliance Testing Scope for this time covers:

Protocol level Maximum power One-sentence interpretation Critical applications

BPP 5W Basic power level, with the lowest compatibility threshold TWS earphone cases, bracelets, low-power accessories

EPP 15W Extended power level, mainstream range for mobile phone wireless charging Phone chargers, charging boards, vehicle wireless charging

MPP25 25W Newest high-power level of Qi2 magnetic charging Magnetic wireless charging, magnetic vehicle charging, magnetic portable power bank

* According to WPC rules, obtaining Qi 2.3.1 authorization means having the testing qualifications for all previous versions of the standard. A wireless charging product can be tested in any power range.

* The MPP25 (25W magnetic level) testing includes higher requirements such as power mode, gain linearization, Mated-Q foreign object detection, etc., significantly increasing the requirements for the laboratory platform and the capabilities of the engineers.

This means that when customers are advancing the development of new versions of products, they can do the following earlier:

01 Planning of certification schemes

Based on product type, technical solution, and certification path, formulate testing and certification plans in advance.

02 Pre-tactical assessment

Identify potential risks before formal certification to reduce repeated modifications due to product design issues.

03 Pre-testing and problem location

Help the R&D team detect testing risks earlier to increase the pass rate of the formal certification test.

04 ATL official testing

Carry out corresponding testing work in accordance with applicable WPC rules and requirements.

05 Technical support during the certification process

Assist customers in handling technical issues that arise during the testing process to improve project advancement efficiency.

 

 

03 Why should we pay attention to Qi 2.3.1 as soon as possible?

For enterprises that are developing new-generation Qi/Qi2 products, a standard upgrade does not merely mean "switching to a new version". It often directly affects:

DESIGN

Product Design HARDWARE

Hardware Solution SOFTWARE

Software Version VALIDATION

Test Validation

CERTIFICATION

Certification Plan TIMELINE

Project Cycle MARKET

Launch Schedule

If it is only after the product has been designed and even entered the mass production stage that differences from the new version‘s certification requirements are discovered, the modification cost will often increase significantly. Therefore, we suggest that enterprises preparing to develop related products:

Pre-position the certification requirements at the product development stage.

The earlier the research and development, testing, and certification are coordinated, the lower the risk of subsequent rectification will be. Certification should not merely be the last procedure after product development is completed; a more reasonable approach is to make certification part of the product development process.

04 The First Time, Not Just a Time Point

For Hongbiao, becoming the first ATL laboratory to obtain the Qi 2.3.1 testing capability recognition is not only an honor but also a responsibility.

The true value of a laboratory is not just having a qualification certificate or a set of equipment; what‘s more important is: whether it can understand the standards; whether it can identify problems; whether it can help the research and development team identify the problems; whether it can make the certification process smoother; whether it can help customers shorten the product launch cycle.

What we hope to provide is not just a test, but a complete certification service chain:

Product development → Pre-test → Debug → ATL testing → Certification

 

05 Continuous Investment, Continuous Upgrade

Technical standards will not cease to be updated, and laboratory capabilities cannot remain stagnant. For a long time, Hongbiao has continuously built laboratory capabilities in the field of wireless charging and has continuously increased investment in equipment, engineer training, and new version testing capabilities.

A truly valuable laboratory should always be better prepared than the customer‘s product development.

When new products, new technologies, and new certification requirements emerge, we hope that customers do not just think "Where can we do the tests?", but rather: "For this project, can we first look for Hongbiao to discuss it?"

This is also the kind of cooperative relationship we hope to establish with our customers.
