How does wireless charging work?

Qi is the product of a group of companies known as the Wireless Power Consortium. The other is the AirFuel Alliance, which makes an array of devices that generally carry the brand name PowerMat.

Even though these two are competitors, the technology used is essentially the same. And most devices will be compatible with one or the other.  

Wireless Charging Coils

Most of the time, the wireless chargers are built with two coils such as the photo above.  To create an electrical connection, one coil acts as a transmitter and the other a receiver.  

The technical term is called "resonant inductive coupling".



Resonant or inductive power transfer works by having a direct current (DC) supplied to the charging system by a power source.

The coils you see is transmitting energy into alternating current (AC) within the transmitter itself.

The AC energizes the transmitter coil to generate a magnetic field.  Once you have a receiving coil nearby, this triggers the AC within that receiving coil.  It also happens in reverse to charge your receiving device.

Wireless charging pad

Think about electric stoves and how it heats up your pan.  The process works very similarly with the wireless charging. But instead of heating up a pan, it powers up your device's battery.



There are several benefits to wireless charging.  But the most obvious one is to not have a bunch of tangled or messy cords.  Wireless charging pads allow producers to make beautiful aesthetically pleasing stands to easily find and charge your iPhone X.  

Tangled Cords

It also allows manufacturers to include more functions, such as cutting the power when your iPhone is overheating, or if the battery is fully charged.

The previous wireless charging pads you experienced at Starbucks or Ikea were really slow.  

Ever since manufacturers found out Apple was going to push for wireless charging in the iPhone 8 and iPhone X as well as their own charging standard. Everyone quickly improved the wireless charging technology speeds and stability.


Emerald Green Wireless Charging Pad

As a design and production firm, our team at MIKOL wanted a high quality, fast charging wireless pad that was also beautiful enough to display in people's living spaces.  A charging pad that can blend in as a decorative item in your home, office, kitchen, etc.

Are you ready for a Qi-compatible charging pad?  When it comes to nightstand charging, office charging or something on the side of the table in the living room, why not pick something that fits into your home decor?
