The Wireless Power Consortium said that Qi open wireless charging standard is capable of providing full support and compatibility for longer distance magnetic resonance technologies.

The consortium has updated the Qi wireless charging standard. The latest addition is a transmitter design that uses magnetic resonance technology, allowing longer range wireless charging. Previously, the standard required devices to be within 5mm from the magnetic platform, but the new update allows 5 watt devices to be charged from a distance of 40mm.

According to the consortium, 12 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.

"The Qi standard continues to quickly grow and evolve as more transmitters and technologies

become part of the specification," said WPC Chairman Menno Treffers. "Qi is backed by over

100 companies and the standard's flexibility allows them to offer a wide range of products with

compelling features and price points. Ultimately, the consumer wins with a broad product

ecosystem that's all seamlessly compatible."

Qi is the global standard for wireless power and charging. Devices are charged just by placing them on, or near, any Qi-enabled surface. Any Qi-enabled device works with any Qi charger, regardless of brand or manufacturer, making charging simple and convenient.
