How Does a Wireless Charger Pad work?
There are days you’ve had to painstakingly try to unknot a tangled charger cord. Or take your smartphone to a repairer’s due to a charging port problem. The solution to making it all simpler is to use a wireless charger. In this article, we’ll go through how does a wireless charger pad work.
If you have experienced any of these problems, then this post is for you. If you haven’t, well, chances are you may experience it later. And that is why you need to look beyond the traditional phone charging. And focus on something way better: wireless charging. And we are going to look at how it works
What is Wireless Charging?
Wireless charging is the act of charging your devices without connecting a cable to its port. I know what you’re thinking; I’ve at one time nursed the same questions before. How does the phone get charged then?
Wireless chargers usually involve a power-transmitting cord attached to a special mat. Placing your devices on this special mat will start charging your phone. How cool is that?
The technology for wireless charging has pretty much been around for the past 100 years. In the ’90s, it was evident in recharging toothbrushes and other household accessories. But it gained prominence from the last 10 years. Tech giants like Nokia, Samsung, BlackBerry, LG, and Apple started developing this tech for their products.
There are also laptops that can be wirelessly charged but are usually incompatible with a typical wireless charger.
What do you need?
Not much, really. In a conventional charge, you need a charger, a cable and a smartphone, all of them being compatible with each other.
To wirelessly charge this is what you need:
- A smartphone that is built to support wireless charging. There are some Android and iOS devices that have been designed to support wireless charging. There are also phone cases or pads you can attach to your device if wireless charging isn’t in-built.
- A wireless charger. They come in a variety of shapes, sizes, and lengths. While most of them are cheap on the market, some are quite pricey. Here’s a little tip: the high-quality wireless chargers are usually steep in price.
How does it work?
Wireless charging is based on electromagnetic induction. Power is transmitted from the socket through the induction coils to create an electromagnetic field. Located at the back of your smartphone is a receiving magnetic plate.
When it comes in contact with the electromagnetic field, an electric current generates. This, in turn, charges your phone.
Like all smartphones plugged with a charging cable, your phone is expected to heat up a little bit. It is nothing to worry yourself over. Albeit, if your phone gets too hot, then there is a problem.
How to use a wireless charging pad
Using a wireless charging pad is actually very easy.
You just have to power up the wireless charging pad and place your phone over it.
Now you won’t have more doubts on how to use a wireless charging pad.
What are the drawbacks?
One of the drawbacks of wireless charging is that you can’t make use of the phone while charging. The reason is that the charging process only happens while the smartphone is landed on the wireless charger pad.
Immediately after you take it off the charging mat, it stops charging. If you make use of your phone all the time, you can wirelessly charge it when you’re about to take a nap.
Another disadvantage is that wireless charging rates are usually slower than conventional charging. So if you want a fast charge, use a cable. Better yet, read our article on How To Get A Phone To Charge Faster.
On the other hand, wireless charging has a great advantage. It’s the safest way to power your phone battery without damaging its port and without tangled cables.
Again, making the move to buy one for your device, you need to check if your phone supports wireless charging.
