What is wireless charging?
Wireless charging has been around for a few years, but only now are more smartphones taking advantage. The amazing technology lets you power-up your favourite devices without any cables, like magic! It’s the future, and it’s here right now. Here’s everything you need to know…
How does wireless charging work?
Here comes the science. Wireless charging – also known as inductive charging – uses magnetised coils to create an electromagnetic field. A moving magnet inside the coil generates electricity – which can be transferred to another coil nearby as a source of power.
So just imagine the other coil nearby is inside the battery of your smartphone. Your smartphone’s battery can absorb this power without having to be plugged into anything. No charging cables are needed.
That’s it in a nutshell. Pretty cool, right?
Why don’t all phones charge wirelessly?
The technology is still relatively new, and only now is it fast enough – and reliable enough – to be considered an alternative to plugging your phone in, but it’s surely only a matter of time before we’re not using cables at all.
What do I need?
The first thing you need is a smartphone that supports wireless charging. Some of the phones that support wireless charging include:
The second thing you need is a wireless charger. More of these are becoming available. These usually look like small docks or mats that you place your phone on top of.
Wireless chargers come in different shapes and sizes and in different price ranges. Some phone-makers such as Samsung even have their own wireless chargers. Now, not all wireless chargers will charge your phone as fast as a wired connection, but there’s no denying how super-convenient they are. The latest wireless chargers are also less bulky - which means they’re more likely to take up less space on your bedside table or desk.
Make sure your phone supports wireless charging
You probably won’t decide to buy a phone just because of wireless charging, but if you do, don’t forget to make sure it’s compatible first.
What is Qi wireless charging?
You’ve probably noticed that many phones such as iPhone Xs and Google Pixel 3 support something called Qi (pronounced “Chee”) Wireless charging. This is just a standard of inductive wireless charging that has been proven to be safe and reliable. Think of it as a mark of quality. It’s not the only standard available, but it’s one that has support from the major smartphone manufacturers.
What does the future hold for wireless charging?
Wireless charging is still a new thing that will soon become a big thing. It’s only a matter of time before we all have at least one wireless charger a home, or on our desk at work. More of them are appearing, and the technology is getting better all the time. They’re getting faster, less bulky and cheaper to buy.
Perhaps one day in the future your home will have a giant magnetized coil inside it, capable of being able to charge your phone while it’s in your pocket (a scary thought). The possibilities are endless. For wireless chargers, this is only the beginning.
