It'll be released later this year

Mobile gadget users will be able to charge their devices from two inches away from the charging device as soon as the end of this year. 
 
According to the Wireless Power Consortium, it will be releasing version 1.2 of its Qi wireless charging standard, which will allow smartphones, tablets and eventually household appliances to be charged from two inches away. 
 
The difference between version 1.1 and version 1.2 is resonance charging. Version 1.1 used inductive charging instead, which means that the gadgets have to be physically touching a charging pad in order to actually charge. 
 
With resonance charging in version 1.2, the receiver and the transmitter won't need to physically touch each other anymore. They can be up to 45mm (1.77 inches) apart. 
 
In addition, the new standard is backwards-compatible, so if you already have a smartphone or tablet with Qi built-in, you can charge them from as much as 35mm away.

Further, it allows multiple devices to charge at the same time as long as they’re within range. 
 
“The WPC is committed to advancing a specification that offers the best user experience without sacrifices in critically important areas to consumers and businesses alike,” said Menno Treffers, chairman of the WPC. “This means backward compatibility with products already in the market and maintaining high-efficiency even over greater distances.” 
 
This could be pretty convenient, especially if you strategically placed Qi chargers around your home, office or car where your smartphone would begin to charge automatically. 
 
The Wireless Power Consortium even said version 1.2 will be able to push as much as 2,000 watts to larger products like kitchen appliances.
 
While we can expect to see version 1.2 products out later this year, Qi chargers for kitchen appliances aren't due out until 2015.
