Qi（发音为“chee”）是世界上实际存在的为小型个人电子设备提供5-15瓦功率的无线充电标准。虽然它主要用于智能手机充电，但该标准也可以很容易地用于为越来越多的消费设备提供电源。目前市场上有超过3,500种Qi认证产品，Qi提供了积极和安全的无线充电体验。无线电源联盟及其650多家成员公司致力于通过提供差异化且价格合理的产品来继续发展扩大这个市场。
什么类型的设备适用于Qi？
智能手机：目前有数百种Qi认证产品（接收器）可用，包括全球大多数手机制造商内置Qi的手机，以及Qi认证的保护盖和保护套，为老式设备增加无线充电功能。近3000个经QI认证的智能手机充电器（发射器）能够为这些设备提供无线电源，消费者可以选择适合自己需要的无线充电器。
笔记本电脑（即将推出）：笔记本电脑和平板电脑通常充电30至60瓦。WPC成员正在努力增加Qi标准的功率配置，以安全地适应这些更高的功率水平，并允许消费者使用相同的技术为他们的笔记本电脑和手机充电。
QI的好处和QI认证的重要性
Qi认证是WPC针对无线充电设备的产品认证计划。WPC使用一个由全球独立授权测试实验室组成的网络，测试特定特性的安全性、互操作性和可用性，每个实验室都可以涉及多个测试程序。只有Qi认证的产品才能带有Qi标志。
兼容性：通过确保所有Qi认证设备协同工作，无论制造商、原产国、所用标准的版本或其他因素如何，Qi标准确保一致且简单的用户体验，Qi认证的设备放在Qi认证的充电器上即可简单工作。
安全性：Qi标准包括许多消费者安全预防措施，包括隔热和异物检测。独立实验室对非认证产品进行的测试发现，它们可以达到几乎200华氏度，足以导致三度烧伤。
如何判断产品是否经过QI认证
只有Qi认证产品才允许在所有产品和包装上带有Qi标志，以向消费者表明该产品已通过认证所需的所有测试。您也可以通过WPC的Qi认证产品数据库中的产品进行Qi认证来确认产品。

Qi (pronounced “chee”) is the world’s de facto wireless charging standard for providing 5-15 watts of power to small personal electronics. Though it is primarily used to charge smartphones, the standard can aalso apply can also easily be used to provide power for a growing number of consumer devices. With more than 3,500 Qi-Certified products on the market today, Qi delivers a positive and safe wireless charging experience. The Wireless Power Consortium and its 650 member companies are committed to continuing to grow this market by delivering differentiated and affordable products.
WHAT TYPES OF DEVICES WORK WITH QI?
Smartphones: There are currently hundreds of Qi-Certified products (receivers) available, including mobile phones with Qi built in from the majority of handset manufacturers around the globe, as well as Qi-Certified protective covers and sleeves that add wireless charging capabilities to older devices.
With nearly 3,000 Qi-Certified smartphone chargers (transmitters) able to supply wireless power to those devices, consumers have a choice of wireless chargers that fit their needs.
Laptops (coming soon): Laptop and tablet computers typically charge at 30 to 60 watts. WPC members are working to increase the power profile for the Qi standard to safely accommodate these higher power levels and allow consumers to use the same technology to charge both their laptops and mobile phones.
QI BENEFITS AND WHY QI CERTIFICATION IS IMPORTANT
Qi Certification is the WPC’s product certification program for wireless charging devices. The WPC uses a network of independent authorized test labs around the globe that test specific properties for safety, interoperability, and usability, each of which can involve multiple test procedures. Only Qi-Certified products are allowed to carry the Qi logo.
Compatibility: By ensuring that all Qi-Certified devices work together, regardless of manufacturer, country of origin, version of the standard used, or other factors, the Qi standard ensures a consistent and simple user experience, where a Qi-Certified device placed on a Qi-Certified charger will simply work.
Safety: The Qi standard includes a number of consumer safety precautions, including heat shielding and foreign object detection. Tests conducted by independent labs on non-certified products found that they can reach almost 200 degrees Fahrenheit—enough to cause up to a third-degree burns.
HOW TO TELL IF A PRODUCT IS QI-CERTIFIED
Only Qi-Certified products are allowed to carry the Qi logo on all products and packaging to show consumers that the product has passed all tests required for the certification. You can also confirm that a product is Qi-Certified by searching for it in our Qi-Certified Product Database.
