Tech Talk: What is Qi Wireless Charging?

What is Wireless Charging?

Wireless charging allows you to charge your electronic device without the use of a charging cable. Typically, a charging pad plugged into a power outlet creates an oscillating magnetic field with the electronic device to charge it.

How Does Qi Wireless Charging Work?

When a compatible electronic device is placed on a charging station, induction coils temporarily act as a transformer. When the charging station generates this electromagnetic field, an electrical current is created in the coil. This electrical current flows into the device’s battery, charging it just as a normal cable charger would (LifeWire).

How to Use Qi Wireless Charging

There are a few products you can sell for students to purchase to utilize Qi wireless charging. Charging stands are a great option for smartphones, smartwatches, and headphones or earbuds. Charging pads are another option for smaller smart devices but can also be purchased as mousepads as well.
