Author:Jake | TIME:November 06,2017

The new iPhone 8, iPhone 8 Plus and iPhone X have come as Qi enable phones that can be charged wirelessly. That’s the first time for Apple to implement this Qi wireless charging technology in iPhone. Actually, wireless charging has been used for some time before the three new iPhones were released. You may wonder how wireless charging works. No hurry, below we will talk about this as well as give a introduction of Qi compatible devices.


What wireless charging is & how wireless charging works

Charging a device wirelessly means you don't need a USB cable to charge battery. Instead, you just need to lay it on a charging mat or puck, which is itself plugged into an outlet; and the inductive charger transfers power to the device. The Wireless Power Consortium has established the Qi protocol, which dictates how the charger and the device work together. However, you should know that Qi chargers work with Qi devices only.

Why charging by induction via wireless charging?

Wireless charging is very useful in many occasions, for example, when your phone runs out battery while power source is not available. Qi chargers are already in hundreds of thousands of public locations around the world. And now more than 90 smartphones from major manufacturers support Qi standard wireless charging, you can expect more businesses to start installing charging mats to lure in customers.


Which smartphones use wireless charging?

In addition to the three new iPhones released this year, there are over 90 smartphones use the Qi standard, among which many are high-end mobile devices. Below are the Qi enabled devices:


iPhone 8/8 Plus, iPhone X
Galaxy Note 8, Galaxy S7/S7 Edge, Galaxy S6/S6 Edge,Galaxy S8,Galaxy S8 Plus(can only support standard charging speed)

Galaxy S5/S4/S3/Galaxy Note 4/3(not Verizon version)/2
Nokia Lumia 820,Blackberry Z30 Verizon


What if I already have a wireless charger? Will it work with Apple's new iPhones?

Yes, if it is Qi certified. The Wireless Power Consortium ensures that every charger that claims to use the Qi standard actually does. You'll know if your charger is OK to use if it has the Qi logo and says "Qi Certified" on its packaging. It's easy to find cheap wireless chargers that say "Qi compliant," "Qi compatible" or "Works with Qi," but these are not legitimate and should not be used to charge your devices. You can buy one at Amazon: CHOETECH T511 Qi Wireless Charger Pad for Qi Enabled Phones.
