The Wireless Power Consortium has now finalized the interface definition for a low-power specification for charging devices wirelessly. The exact details will be published publicly on August 30th. The specification is currently limited to 5 Watts, more than enough for all USB-charging Symbian-powered phones. Devices that want to comply with the standard will have to pass third-party certification before the manufacturer is allowed to use the 'Qi' logo on the device or its packaging.
"Our customers will see the Qi logo and know: this product works with my other Qi products," wrote Menno Treffers, a senior director of standardization at Philips who works with the consortium. "Publishing a standard is not enough. Without test documentation, certification services, and a logo license agreement, interoperability is an illusion."
Certification testing services will begin in August, meaning products supporting the standard could start appearing this fall.
