Wireless chargers help make your workspace tidy and clutter-free. You can usually charge varieties of smartphones with it. iPhones may require a different setup. But the relief of not looking for cables all over the house or office is really peaceful!
Wireless chargers have been globally used for the past few years, but people are often skeptical about it. Some say they reduce our phone’s battery power, some say it takes too long to charge, and some others show many other drawbacks. Yet, it’s a good alternative to chords.
In today’s article, I’ll discuss some of the trending best 15W wireless chargers and also shed light on the merits and demerits of using them. Also, there are some guidelines to follow when you go to purchase one. I’ll discuss those as well.
First, let’s understand how a wireless charger works.
The Basics of Wireless Charging
Wireless chargers come in the shape of either a round plate or a car dashboard. It’s not wireless because there’s a wire that connects to the power source. You’ve to place your phone on the plate or mat or stand and it starts charging automatically.
This is why you shouldn’t place any other metal object on it as it will either start supplying power and make the surface and the object hot or if the charger’s got sensors, it will start showing signals.
Your phone has to be Qi-enabled to function with a wireless charger.
So… What’s Qi?
The term is actually pronounced as “Chee”. It’s one of the forerunning technologies of wireless charging. It’s also the most widely used one because of its compatibility with most of the devices. These primarily came as chips and producers didn’t include them in the phones.
With time, Qi standards started using both inductive and resonant charging, allowing it to be compatible with both forward and backward charging processes. This made Qi popular among manufacturers, and they developed Qi-enabled phones for the market.
Advantages of Qi Charging
Let’s look at the merits in brief. Firstly, you don’t have to look for cables when you’re super busy with work and kids! And often, the charger and your phone’s charging port get damaged by rapid plugging in and out. Just place the phone on the stand or mat, and it starts!
Secondly, you don’t have to worry about the timing. Most of the wireless chargers stop the power supply the moment your phone gets full. And the place’s versatility is amazing! Cars, mousepads, and even desks nowadays have a built-in wireless charging facility.
You can charge your smartwatch, smartphone, etc. on the go. It saves you much hassle when you’ve to rush to your office or the mall or your kid’s school. Besides, you can charge multiple brands and products with it, both your Android phone and your iPhone.
The Disadvantage of Qi Charging
There are three basic demerits of wireless or Qi charging. Firstly, the charging speed is really slow! You still have to opt for wired charging if you wanna charge fast. Also, you can’t use your phone while charging. That’s a healthy habit though!
Another funny yet annoying issue is the placement. You’ve to put the phone properly on the charger or else it won’t charge. Sometimes you’ll be surprised that your phone didn’t get charged even after a couple of hours only because it wasn’t placed at the right point!
How to Be Sure that Your Phone Is Qi-Enabled?
The simplest answer to this is – find the Qi logo! If your phone is Qi-enabled, it will carry the logo. Apart from these, there are two other factors.
Firstly, manufacturers now include a glass back for Qi-enabled phones. Metal backs pull the current, causing the power supply to go down. It takes even longer to charge and is unsafe as well. Besides, your phone battery will contain specific antennas for receiving the current.
There are some problems you might face while using Qi charging. Your phone cover may hinder the charging, so you’ll have to take it off before charging. Moreover, if the phone’s on vibration mode and you get a call or text, it may displace it from the charging point.
There’s an alternative solution to this. Buy an external adapter and put it on the back of the phone so the device sticks to the charger. But check before buying if your phone supports an external adapter.

How to Pick the Best 15W Wireless Charger?
Electronic devices are tricky. You gotta know a lot of terminologies and their meaning to compare multiple products. Chargers are specifically more sensitive as they must be compatible with the phone or device to be charged.
So how do we ensure that we’re buying the best 15W wireless charger among all the thousands of options? The following points might help –
Chargers’ safety certifications are provided by Wireless Power Consortium (WPC). Their certification ensures that the charger is tested to be effective and safe and also compatible with Qi charging. Sometimes chargers may not have the certification which isn’t unusual.
However, having a certification is better and you’d wanna spend your money on a sure-shot product too. Some of the chargers have received certificates to be effective for magnetic and metal covers recently. But the majority of the chargers still prefer not to deal with them!
Power Supply and Source
The chargers I’ve mentioned here are either USB-enabled or have AC adapters. USBs can be both micro and type-C. However, type-C is best for the latest devices as they fit better. The length and quality of cords also matter and their replacement availability in the market matters more.
In this case, the wall charger quality and type are also important to consider. On the one hand, you’d wanna save electricity bills by purchasing an auto power charger, and on the other hand, you’d prefer the speed of charging, which depends on the power supply.
There are different charging methods, but Qi is the most widely used wireless charging technology. If your phone is Qi-enabled, you must buy a Qi charger. And not only phones but also other devices are now Qi-enabled, so you can charge multiple devices with one charger.
Speed and Wattage
Most of the Qi chargers support up to 15W, but there are variants of 7.5W and 10W. The more the wattage, the faster the charging. Android and iPhones usually charge with a speed of 15W if connected to the right charger.
I’ve mentioned some chargers here that support both 7.5W charging and 15W charging. Versatile chargers are better options as they offer power variations based on requirements. Therefore, you should look for a charger with a maximum capacity of 15W.
As mentioned above, wireless chargers can come in different shapes such as pad, stand, or mat. The better choice will be a circular flat mat. These are easy to place anywhere such as on your desk, car dashboard, etc. they’re small and handy and easily portable too.
You can look at the screen while charging because the surface is compatible. Also, you should consider the non-slippery feature. Your phone sometimes gets damaged by one single drop throughout its lifetime.
The structure also includes the lighting criterion. An LED light makes it easier to understand if you’ve placed the device properly on the charger and if it’s started charging. Besides, they help to detect foreign materials on the charger’s surface.
Most of the latest chargers include a cooling fan to prevent heat while charging. This has two major benefits, one is the efficiency stays consistent and the other is it doesn’t create noise while charging. Your device and the charger also survive longer because of this.
The electronic market is flooded with random products from random brands. It takes both an understanding of the instrument as well as the cost of the product to determine which charger is actually good. You should, therefore, always choose a reputed brand.
Also, you won’t wanna buy a charger every couple of months, right? So, better spend a little more at the first time to ensure the charger survives and performs well.
And reputed brands offer warranty and post-sale services that random brands don’t. And both of these are really important because you may need assistance anytime after you’ve started using the charger.
Frequently Asked Questions
Despite getting so much information, it’s normal to be confused about many other issues related to chargers. I’ll try to answer some of the most common questions people ask before buying a wireless charger below.
As we’re talking about 15W wireless chargers only, I’ll try to keep it relevant.
How Fast Is 15W Wireless Charging?
People have been skeptical about wireless charging because of its speed. However, the latest chargers are Qi-enabled which increase their speed to a great extent. These can almost double the charging speed for most devices.
It’s been possible due to the development of internal hardware with Qi technology. Before that, people used to buy wireless chargers for portability, design, and utility, etc. Even if the wattage was higher, the charging speed wasn’t. The changed scenario has made them popular.
Can Wireless Charging Damage Phone Battery?
Not really. All the branded and most of the non-branded chargers are built in a way to protect your battery and back cover while charging. The LED indicator is one of the ways to alert you that your phone hasn’t been placed properly and might not get a proper charge.
The non-slip surfaces are also created to protect your phone’s back as well as prevent it from falling on the floor and hit hard. However, unfortunately, there are some very popular rumors about wireless charging and its efficiency.
Why Does My Phone Get Hot While Charging?
The major reason is the inefficiency of the charger. They can’t turn the whole power supply into charge and therefore get hot. Make sure you buy a high-quality charger, and a cooling fan will be an added benefit in this case. This isn’t a big concern but shouldn’t continue in the long term.
Is Charging Overnight a Good Thing?
The answer is both yes and no. the latest chargers are enabled with auto power control so they stop the power supply the moment your phone is fully charged. Yet, they might emit some heat that can hurt your phone’s longevity.
It’s best not to keep your phone on charge after the charging’s done and better keep the charge between 40% – 80%.
Choosing the best 15W charger requires some research and understanding. It might seem complicated, but wireless charging is more convenient and efficient. Tech Companies will keep coming up with better chargers in the near future and soon you’ll find it hard to get a wired charger!
Read the user manual with each charger and be patient with the use. Sometimes the performance may not be as per your expectation but if you try more carefully, you’ll see the charger serves really well.
Most of the phones and AirPods and smartwatches are now Qi-enabled which makes it easier for you to use one wireless charger for many devices. Carry it to your office and back home or on trips, they’re cool.
But remember to be gentle with the chargers or else they’ll get damaged due to heat or hit! Avoid putting foreign objects and forcing the device to charge. Rather, see if the power supply is compatible and if you’ve put the phone at the proper point.
Hope you’ll have a great journey with your new wireless charger!
