Smartphones with integrated Qi receivers (Qi phones) are widely available in Japan, Europe, and the USA. The first Qi phones have reached China, India, and most other countries. Some of the prominent Qi phones are:
The Samsung Galaxy S3 can be changed into a Qi phone by replacing the battery door. The iPhone 4 and 5 can be made into a Qi phone by using a sleeve or cover.
You want to charge wirelessly at home, in your office, in your car, and in public areas such as coffee shops and restaurants.
Your private charging infrastructure develops first. That's were you get an immediate benefit from owning a Qi phone. See what user users write about their Qi phone:
"Once you have a wireless charger around, then using it becomes second nature, you top-up more often than you would. It’s one tiny hassle removed from the day." - Andrew Orlowski, The Register
"[Wireless charging] is not a must have, but once you have it, you’ll wonder how you ever lived without it." Michelle Maisto, eWeek
“The convenience of simply dropping the Nokia Lumia 920 on the Fatboy pillow is great. I have it sitting on my desk so when I am there the Lumia 920 is charging up which can lead to it being charged up more often.” Mattew Miller, ZDNet
You can buy a wide range of chargers for home and office use. At home your phone can relax on a Fatboy charger. In the office you might prefer something more energizing. In our certified product database you can find more than 50 different chargers.
All Qi chargers work with all Qi phones. Really! Check the logo on the product, or on the products packaging and documentation. It works seamlessly if you see the Qi logo.
"The [HTC Droid] DNA features Qi wireless charging technology. The phone began charging within a couple of seconds after being placed on the Nokia Lumia 920's charging pad." - Sherri L. Smith, Laptop Mag
You are not going to carry a wireless charger when you are travelling. A USB charger is more convenient to carry with you. But what you would really like is Qi charging spots at your local coffee shop and in other public spaces. That public infrastructure is already developing.
In Japan the public charging infrastructure is furthest developed because Qi phones were introduced a year before the introduction uin the USA and Europe. More than 300 public charging locations were operational in Japan by September 2012. NTT-Docomo recently announced that another 10.000 public chargers will be installed before March 2013.
The public infrastructure is created by the owner of public spaces, such as coffeeshops and restaurants. These owners will invest in the wireless charging infrastructure when this new service helps them attract customers. When more people own a Qi-phone, the business case for the owners becomes more attractive. It is just like WiFi. Starbucks started to offer WiFi in 2002 when many of their customers started to carry WiFi capable laptop computers.
