The Qi standard is a fully open and flexible platform, and as it evolves, the WPC regularly approves new transmitter designs proposed by its members. The latest addition is a transmitter design that uses magnetic resonance technology. It increases the distance devices up to 5 Watts can be charged, from 5mm to 40mm, while remaining fully Qi compatible. This transmission distance is suitable for charging through most tables and counter tops.

Wireless charging stations such as those that can be built into furniture, tabletops, cars, or found in charging pads, typically use magnetic induction or magnetic resonance transmitters to send power to the portable devices they’re charging. Having the flexibility to choose from multiple transmitter designs allows companies to offer a wide range of Qi product types in consumer electronics, home appliances, furniture, automotive and other markets. These products can then be further differentiated by innovative design, components, materials, functionality, and value. Any Qi-enabled charger works with any Qi-enabled device, no matter what transmitter type.

Twelve new transmitter designs are approved in the specification, including those offering more freedom in device placement, magnetic and non-magnetic device alignment, and differing power options, such as USB. Many other designs are under review, with plans for additional spatial freedom and distances, increased power levels and more options to charge multiple devices at one time.
