Wireless charging is become popular among different electronic devices. How wireless charging works? Does it work on all kinds of smartphones?


Wireless charging has been around since the late 19th century, but for about 100 years it was a technology without many practical applications. Today, there are nearly a half dozen wireless charging technologies in use, all aimed at cutting cables to everything from smartphones and laptops to kitchen appliances and cars. That's why we need to know more about this advanced charging technology.


What is Qi Wireless Charging?

Qi Wireless Charging with a wireless energy transfer of up to 5 watt. It is the universal standard for wireless charging of battery operated devices like cell phones, iPods, MP3 players and cameras. Wireless charging is a technology that allows charging over (very) short distances without cables.

The advantage of wireless charging is that it’s quicker and easier, as you don’t have to plug and unplug each time – you just place your device on top of your wireless charging power bank.

How Does Qi Wireless Charging Work?

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 most popular wireless technologies now in use rely on an electromagnetic field between a two copper coils, which greatly limits the distance between a device and a charging pad. That's the type of charging Apple has incorporated into the iPhone 8 and the iPhone X. In the case of smartphone wireless charging pads, for example, the copper coils are only a few inches in diameter, severely limiting the distance over which power can travel efficiently.
