What is a Qi charger and Qi charging standards
Some international standards allow short distances charging without the use of cable or any wire and one of the most popular standards is a Qi standard. Qi is a Chinese word that means natural energy. It allows distance up to 1.6 inches between charging transmitter and Qi-enabled device. User doesn’t need to plug in and plug out every time, with the help of wireless charger, Qi charging allows you to charger Samsung, Apple, Huawei, HTC, Google Pixel, and Nokia smartphone's through wireless charging.
How do Wireless Chargers work?
The most convenient way is to charge/fill up your phone's battery without the use of a charger. Through a coil alternating current is sent to a receiver side to generate a magnetic field and on receiver side coil convert that magnetic field into an electric current and phone starts charging. For wireless charging, you just need a wireless transmitter/plate along with cable and a Qi charging/ready device. Many Qi-ready devices don’t have a built-in coil but have aftermarket receivers that help in wireless charging.
Use of Phonecase/cover while wireless charging
A bad quality phone case can become a hurdle in wireless charging because you have to put your phone on a charging plate. The phone case should be metallic or a leather Wallet phone case or made of leather or Silicon material. The thickness should be greater than 5.5mm, so your phone gets quickly charge with no obstacle.
