What is Wireless Charging and how does a wireless charger work?

  Wireless charging is getting increasingly popular and more and more branches are realizing its potential and value. It is the future and answers to the fast-growing demand for power and being able to charge everywhere. As the demand for non-stop power grows, so does the demand for charging mobile devices faster and faster.  As a wireless charging expert, we would like to explain more about wireless charging and how does a wireless charger work.

  Qi Wireless Charger with a wireless energy transfer of up to 15 watts.   Qi (the Chinese word for “energy flow” pronounced like the “chee“ in “cheese“) is the universal standard for wireless charging of the battery by WPC.
  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 elementary: the Qi transmitter (Charging Station) transfers the required energy to the Qi receiver (the mobile phone).  
  Modern wireless power draws on the same principle that Tesla investigated over a century ago: induction. Electromagnetic induction—using an electromagnetic field to transfer power between two objects—forms the basis of all modern wireless charging, as well as things like contactless payment, cooktops, and wireless speakers.

  In a practical sense, the way induction works are simple: First, you feed power to a base unit or wireless charging station that contains a “transmitter” coil. An electromagnetic field forms around the transmitter and when a second “receiver” coil comes near enough, the receiver coil interacts with the magnetic field to create an electric current. By putting the second coil inside another device, you can wirelessly transfer power from the base to the device.
  Most induction chargers only operate over a short distance, however, and while physical contact between a device and its base unit isn't necessary for induction to work, the fields generated lose so much power as the devices get farther away.  It's usually the only way to get the two coils close enough, which means we need to put the mobile phone near close to the charger pad.
