The wireless power transfer occurs through electromagnetic induction. With inductive charging the required power reaches the device not through a traditional cable but rather wirelessly through the use of electromagnetic fields. The principle is very simple: the Qi Sender (Charging Station) transfers the required energy to the Qi receiver (the mobile phone).
The biggest advantage of Qi Wireless Charging technology is that cell phones and chargers from different manufacturers are compatible. The only requirement is that both parts the sender and the receiver fulfill the Qi specifications.
Therefore, every Qi enabled device is compatible with every Qi charging transmitter, regardless of the manufacturer or make of the device. Numerous cell phones, including from market leaders like Nokia, Samsung, Sony, LG, Motorola and HTC,already comply with the Qi standard and can therefore be charged by any Qi Charging Station. The number of enabled devices is constantly growing as Qi wireless charging technology is integrated by an ever-expanding list of manufacturers. This allows you to charge your various battery operated electronic devices with just a single charging station.
