It has been a gimmick for several years but is becoming the new norm. Today, it’s one of the first parameters we consider making a purchasing decision. It does have many flaws, but most users tend to overlook them all. It is the Wireless Charging!
Wireless charging started creeping into our daily lives not so long ago. Still, we all have a wireless charging stand somewhere around us.
The convenience of this method is fantastic, but the efficiency is somewhat lacking. Or so it was.
While the mainstream speed for smartphones wireless charging is 5-7.5 W, there are samples of much higher capacity, like the Xiaomi Mi 10 Ultra, that supports up to 50W wireless charging. Or the generic Xiaomi Mi 10 line that supports up to 30W wireless charging.
There is a ton of wireless charging options and technologies. Some use a mat of some sort, some still emerging, that need no touching the device at all. And while there is an established industry standard for when there’s a mat involved: the QI, the touch-less options are yet to develop a unified standard.
While having your devices charged without needing to even put it down anywhere is fun and exciting, there’s some argument about how good or harmful it might be. However, we do have wi-fi in nearly every home today, although the same fears ever followed it, as do now follow the wireless charging.
So, what’s the most enhanced and widely available wireless charging solution?
By far, the most enhanced option seems to be the Xiaomi 20W Smart Tracking Charging Pad. It boasts a coil that will find your QI compatible device anywhere on the surface.
All the other options on the market are either a simple coil in a mat or a mat containing several coils. They vary in power and the number of devices. Now that definitely is not perfect!
So, what do we want from the perfect wireless charger?
Well, firstly, if we’re talking perfect, it has to be a small device that will turn any surface into a wireless charging pad. No devices number limit, no nothing.
And it has to be powerful. With smartphones accepting up to 30W wireless charging, you don’t want to have anything under 50-60W.
It has to be harmless. I still want to use my desk as a desk, even though I have my phone charging somewhere on it.
Today several wireless charging solutions exist that can be built into furniture or attached under a table to make a single spot on it charging, like the Hudly Invisible Wireless Charger. But it’s just one spot.
So, the perfect solution is not there yet. And, honestly, we might be kept waiting for it for a couple more years because safety and health hazards have to be tested. But there are several promising options using radio waves and even light to charge devices in a large area.
For example, GuRu Wireless uses radiofrequency to charge e-labels for places like Walmart. Or the Wi-Charge that uses infrared lights to charge the sensors in public restrooms. Or the Energous WattUp that uses magnetic resonance to charge devices in a room.
All these technologies are still raw and need some testing and tuning. But that is where the industry is to end up: spreading energy like the internet of today. So, hopefully, we will receive the perfect wireless charger soon enough.
