In September , the Nokia became the first commercially available smart phone to offer built-in wireless charging capabilities based on the Qi specification.
The latter's member roster includes Apple, Google, Verizon and a veritable who's who of electronics manufacturers. The WPC created the most popular of the wireless charging standards — Qi pronounced "chee" — which enables inductive or pad-style charging and short-distance 1.
The Qi standard is being used by Apple. The Apple Watch, launched in , uses a inductive wireless charging cable, which still requires the device to be tethered to a cord. The PMA and its Powermat inductive charging specification found success by piloting its wireless charging technology in coffee shops and airports.
Starbucks, for example, began rolling out wireless charging pads in With competing standards, support for mobile devices remained fragmented, with most mobile devices needing an adaptive case to enable a wireless charge. In , Starbucks announced it would roll out wireless charging based on the Powermat specification for its customers in the U.
AirFuel has also announced wireless charging at some McDonald's restaurants. That, according to Freas, is one way wireless charging could see wider adoption. AirFuel has focused on two charging technologies: electromagnetic resonant and radio frequency, which offers the ability to move around a space and still have your mobile device charge.
Both technologies offer distinct advantages in terms of spatial freedom, ease of use, and ease of installation — big factors in creating market value and customer satisfaction," said AirFuel spokesperson Sharen Santoski.
As a result, Santoski said, a growing number of coffee shops, restaurants and airport have deployed resonant-based wireless charging stations. AirFuel recently announced a project with the Taoyuan Airport Metro, which is putting Resonant charging in its trains and stations. And furniture maker Order Furniture has created a new line of Resonant-enabled furniture. Most of these projects are still just pilot programs, Freas said, adding that consumers and businesses are less likely to want tightly coupled charging and more likely to opt for loosely coupled resonant charging That's because loosely coupled charging provides more spatial freedom — the ability to simply drop a phone, tablet or laptop on a desktop and have it charge.
The Dell wireless charger offers up to 30W of charging power, so a Latitude laptop will charge at the same rate as it were plugged into a wall outlet. But WiTricity's main focus is the auto industry. The company, which is part of the AirFuel Alliance, expects a number of electric car manufacturers to announce wireless charging for their vehicles, according to WiTricity CEO Alex Gruzen.

But it lost the format war if you like, so Powermat said in that it would develop commercial wireless charging technology compatible with Qi.
Qi has three separate power specifications, beginning with low power, which is primarily what we're talking about here, for charging mobile devices.
At the moment there are several wattages that can be applied to this. However, individual companies can develop their own technologies to deliver faster wireless charging speeds. Many peripheral manufacturers now have their own wireless chargers including Anker, Belkin, Logitech, Moshi and Mophie. Some of these look like mats or pads, others like desk stands.
Wireless charging is now appearing in a variety of places; Swedish flat-pack extraordinaire Ikea has a number of pieces of furniture , mainly side tables and lamps, that have Qi wireless charging built into them. The furniture chain sells standalone wireless charging pads too, as well as a range of cases for different phones. Apple's own wireless charging mat - called AirPower - never actually launched but there are many third-party versions that will charge your iPhone, Apple Watch and newer AirPods have a wireless charging case as do many other wireless earphones now.
Some phone cases such as wallet cases might be too thick for wireless charging to work properly. Because metal is too thick for the electric current to reach the battery, your phone is unlikely to charge properly.
This depends on the charger. Some have two or three pads for multiple devices, but most have just one and can only charge a single phone at a time.
