Qi Wireless Charging Explained And How It Works

Many problems characterize charging different devices using wired or corded chargers. First, the cords easily get entangled to create a mess that may be difficult and annoying to undo.  What’s more, the plugs wear out and wires bend with use, making the charging process ineffective.

It is for such reasons that most people have moved on to the Qi wireless charging technology.

Have you?

Qi wireless charging is not only simple and convenient but it presents many more possible applications as well. 

Possibly, this revelation sounds interesting and this far you are wondering; so, can I make my phone qi compatible? 

Well for this and much more information about Qi charging, please read this article to the end.

What is Qi charging?

Qi is an open interface standard that describes wireless power transfer by inductive charging. The system comprises a charging pad upon which you place your device to charge via resonant inductive coupling. It was initially released to the market in 2008 and by 2020, it had been adopted by more than 200 tablets, smartphones, and other compatible devices.

 How fast is qi charging?

Although the Qi 1.2 standard delivers a maximum charging speed of 15 watts, which is 9volts, 1.67 amps, the gadgets doing 7.5 W – 10 Watts are more common today. If you have an iPhone, you can expect speeds of up to 15 W with an Apple-certified MagSafe Charger and 7.5 W for a regular Qi charger.

The majority of Android phones can take speeds of up to 10W, although, some of them support the 15W charging speed.

You must also be knowing the 5W chargers. Although these are much slower, they are considered by many users as a low-cost option. These take roughly 3-4 hours to give you a full charge.

Do wireless charging work on all phones?

 Not exactly! However, a wireless charger can effectively charge any smartphone that is compatible with the Qi wireless charging standard. 

What are the advantages of wireless charging? 

So, who qualifies to use a wireless charger?

Well, you can use this device if you own a smartphone that is customized to support the Qi wireless charging standard. Perhaps one of the leading advantages of using this gadget is convenience. For example, if your phone does not have a headphone jack, you can still use wired headphones while charging because a wireless charger doesn’t use a USB-C port or a lightning connector.

Two, with a wireless charger, you won’t have to go through the hustle of plugging and removing the cable. In effect, this minimizes the damage to the charging port

In brief, Qi wireless charging

(1). Is a safer way to charge your phone

(2). Is simple to use because all you have to do is place your phone on the charging pad

(3). Has less impact on your phone’s charging port.

(4). Pads are installed in cars, buildings, and several other public places for convenient access to the charging service.


Generally, wireless charging works much slower when compared the ordinary chargers, more so for handsets with quick charge technology.

Also, when your phone is charging on a cable charger, you can still receive and make calls without disrupting the charging process. However, the case is different when using a wireless charger because once you remove the phone from the pad, it stops charging immediately.

Another disadvantage is that not all phones have the wireless charging feature
