Qi Can Now Charge Devices Wirelessly Up to 40mm Away
Apr 20, 2012, 7:41 AM by Eric M. Zeman
The Wireless Power Consortium today announced that it has updated the Qi wireless charging standard to allow inductive charging to take place over longer distances. Previously, the standard required that devices be within 5mm of the magnetic charging platform. With the updated standard, 5 watt devices can now receive a wireless magnetic inductive charge when placed up to 40mm away from the charging platform. The WPC also added 12 new transmitter designs to the specification, which offer consumer electronics makers more freedom in device placement, magnetic and non-magnetic device alignment, and differing power options, such as USB all while remaining Qi compliant. Together, these changes will allow the Qi-enabled charging platforms to be build into more surfaces, such as counters, desks, tables, and cars.
