A wireless charger is a device that will allow you to charge a given device without the need to plug it in. An example of this would be the flat, disc-looking ones that can be found pretty much everywhere. In order to use it, usually, you just have to place, say a phone, on the device. Then, it will begin automatically charging your device.
But does the charger itself need to be plugged in?
While most wireless chargers do need to be plugged into an outlet, some are equipped with a rechargeable battery allowing you to charge your device even if a power outlet is not readily available.
Let’s now take a look at the different types of wireless chargers in the market and how they operate.
Does a Wireless Charger need to be Plugged in?
A wireless charger’s battery power cannot come from thin air, and despite the radical advancements in technology every single year, we have yet to develop the necessary technology to allow chargers to be powered from a distance. So, that means a wireless charger must, ironically, be wired to give out charge in the first place.
Of course, mind you, it also depends on the model and makes of the charger in question. Some have batteries they can be charged with, but those batteries often need to be replaced, so many people opt for the wired version just to make it slightly less tedious of a task.
So, now that’s out of the way, there is a question to ask. Is wireless charging faster than just plugging it in?
Well, as usual, it depends.
In most cases, plugging in a device is faster than using a wireless method, as the power is being directly routed to the device’s energy storage, while with wireless, it has to go through the case and around various parts in order to reach the power storage.
Though mind you, that’s only for the less expensive ones. The real high-end wireless chargers are capable of charging a device much quicker than the wired counterparts. Though, those only work with devices from the same manufacturer.
Also, one other thing, despite the name, it’s not a power bank for your phone. I know that there are some phone chargers you can take with you so you can charge your phone on the go.
Not like a car charger, more like something you carry with you as you walk, such as a long hike or going through a convention.
They’re mostly small objects you can fit inside of your palm, but wireless chargers are rather different.
Wireless chargers require a stationary device to be placed on them and are rather delicate. They aren’t meant for on-the-go travel, but a power bank is supposed to have a direct line to your device via a cable. In a way, they are wired chargers, just without the external power source.
Now, I’m going to recant my words for a second and say that there are some ways to use a power bank as a portable wireless charger, as there are a few that can clamp to the back of your phone and charge it that way.
If I’m charging a phone, and it’s encased, do I need to take it off?
So long as there isn’t anything electronic or magnetic in the case, then you should be fine. Wireless charging uses electromagnets to charge your phone; anything that interferes with that process would affect your phone. But, if your phone case is plastic or wooden, you should be fine.
Can Wireless Chargers work beyond just phones?
Again, it depends on the device and manufacturer. Some can charge multiple devices, sometimes all at once, but those are special ones.
Now, all this talk of wireless charging brings to mind an interesting question, does a wireless charger need wifi? Well, again, the answer is no. Wifi is for internet access; wireless charging is for a device’s power supply. It is like two rivers going in completely different directions.
Any cons to using a wireless charger over a wired one?
You do need a phone or device that is capable of being charged wirelessly, and those are rather expensive. For those who don’t have the cash to spare, then going with a wired charger is often the better choice.
Another reason is that you can’t use your device while it is being charged, as the devices need to focus on being charged. You cannot sit with the device while it’s charging, nor can you use it at all while it’s being used. Until the device in question is fully charged, it’s basically a plastic brick.
In contrast, you are free to use your device while it is being charged with a wire, so if you’re lucky enough, you’ll either have a long enough cable, or a close enough outlet, for this to be a non-factor.
So, that’s it for how Wireless Charging works and whether or not it needs to be plugged in. I hope you enjoyed this article!
