Charging wireless devices without chords

Imagine charging your wireless devices without having to deal with the clutter of chords.
All you need to do is just place the device on the charging pad.


Welcome to the world of inductive charging, the next generation of intelligent charging. By transferring energy using an electromagnetic field, charging pads are able to intelligently communicate to and from devices they’re charging.


How Does this work
Inductive charging uses electromagnetic fields to transfer energy from a charging pad to a compatible special receiver on or in a device. The power transfer happens when the charging pad is connected to the AC wall outlet and a compatible receiver is placed on the surface of the pad.


Just as inductive charging is the first generation of intelligent charging, Qi is the next generation. Before Qi, not all transmitters and receivers were not compatible with each other. This is why the Wireless Power Consortium made Qi the universal standard for inductive charging. Now, with the Qi standard of Inductive Charging, all Qi-enabled devices that need up to 5 watts of power have coils that transmit and receive the same frequency. So from now on, any Qi-enabled device will work with any Qi charger.


Qi allows you to charge smartphones, cameras, mp3 players and anything else that needs 5W or less without directly plugging the devices into anything. Since it is an open-sourced, interoperable standard, it is very similar to other open standards like Bluetooth® and Wi-Fi™. It is anticipated that the Qi universal standard will be broadly adopted by mobile device manufacturers, providing you with the freedom to charge all Qi-enabled devices on a single station without multiple cords and eventually without accessories.


The Energizer® Inductive Charger
One such charger, the Energizer® Inductive Charger charges up to 3 of your critical devices at a time. Two inductive Qi charging zones are located on the top surface of the pad for hassle free charging. Any device that has Qi either built into it or is enabled through a Qi accessory can be charged here. Energizer® offers Qi inductive charging sleeves for iPhone® 4 and iPhone® 3GS/3G and a Qi inductive door for the BlackBerry® Curve™ 8900 (each sold separately). The USB port on the back of the charger supplies 5V, 500mA (2.5W) for charging additional phones, headsets, mp3 players, cameras, GPS devices and more (up to 5W).


That’s the power of Qi.- charging into the future.
