Introduction
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 also apply and easily be used to provide power for a growing number of consumer devices. With more than 3,700 Qi-Certified products on the market today, Qi delivers a positive and safe wireless charging experience.
THE IMPORTANCE OF STANDARDS
Any electronic product must be designed and manufactured to meet safety and operating standards. The Qi standard has incredible industry support and the WPC’s role has been to create and manage strict certification procedures, ensuring manufacturers deliver products that are safe and effective and that are compatible across the Qi ecosystem. This means if your wireless charger is Qi-certified, then you can be sure that it will charge every Qi-certified phone or other product on the market.
Each product that has been certified to meet the Qi standard can carry the Qi logo, which means you can expect it to perform as expected and to do so safely. Look for the Qi logo, and check products in the database (see below).
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 more than 3,200 Qi-Certified smartphone chargers (transmitters) able to supply wireless power to those devices,consumers have a choice of wireless chargers that fit their needs.
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.
Others
Authority: The Wireless Power Consortium created and maintains Qi (pronounced “chee”), the global standard for compatible wireless charging. The Qi standard guarantees that any device carrying the Qi seal will work with any charging surface that also carries the Qi logo, regardless of manufacturer or brand. Qi is backed by hundreds of industry-leading companies because it allows design freedom, product differentiation and guaranteed wireless charging interoperability. WPC also provides easy access to the essential patents using reasonable and non-discriminating terms (RAND).
