What Is a Qi Wireless Charger?
A Qi wireless charger is a device that enables wireless charging of electronic devices, such as smartphones, watches, and earbuds, using electromagnetic fields to transfer energy between a transmitter and a receiver. Qi (pronounced “chee”) is an open interface standard for wireless power transfer, developed by the Wireless Power Consortium (WPC), a group of companies that include leading technology brands like Apple, Samsung, and Google.
How Does Qi Wireless Charging Work?
Qi wireless charging works on the principle of electromagnetic induction, where an electromagnetic field is generated by a transmitter coil in the charging base, and this field induces an electromotive force (EMF) in a receiver coil in the device to be charged. The EMF is then converted into electrical energy, which is used to charge the device’s battery.
The Qi standard specifies a range of frequencies for wireless power transfer, including 100 kHz, 200 kHz, and 135 kHz. The most commonly used frequency is 100 kHz, which provides a good balance between efficiency and safety.
