The first version of the specification allowed four types of transmitters. Two multi-coil arrays, a moving coil, and fxed single coil transmitters. And each type allows different shapes and sizes where manufacturers can make their own trade off between cost, user experience, and design. We are now further increasing the freedom in transmitter design. Members of the consortium have proposed several new transmitter types. These new types are added to the specification when analysis has shown that the new transmitter will not cause incompatibilities with the existing Qi power receivers.&nbsp; We will continue to add new transmitter types. For details see: <a class="jive-link-external-small" href="http://www.wirelesspowerconsortium.com/blog/15/compatibility-or-freedom" rel="nofollow ugc noopener" target="_blank">http://www.wirelesspowerconsortium.com/blog/15/compatibility-or-freedom</a>. Here you can read how we make sure that new transmitters will not cause incompatibilities. </p><h2>Extension to 10-15 Watt</h2><p style="margin:0;">The Qi low power specification now guarantees the delivery of 5 Watt into Qi receivers. We are creating a certification program for Qi transmitters that can deliver uo to 15 Watt. These Qi transmitters provide rapid phone charging.</p><h2>Extension to medium power</h2><p style="margin:0;">The Wireless Power Consortium has started work to extend the Qi specification to medium power. The low power specification delivers up to 5 Watt, the medium power specification will deliver up to 120 Watt.</p><h2>Wireless Power in Kitchens</h2><p style="margin:0;">Cable- and connector-free appliances make kitchens safer, more convenient, and provide a whole new way of working with appliances. These applances need significant power to drive motors and cook food. Wireless kitchenm power will deliver up to 2 kW.</p><div style="clear:both;"></div> <div style="font-size: 90%;">Tags: wireless_power_charging, texas_instruments, würth_elektonik, wp_challenge_one, wireless_power_consortium</div>
