The Ultimate Guide to Wireless Charging Pads
Wireless charging technology enables device charging without a physical connection to a power source. This is useful for users who want to charge their devices without tangled cables or plugging and unplugging chargers.
It can also be helpful when it is difficult to find a power outlet, such as when travelling or using a device in an area where outlets are scarce. Furthermore, some people believe wireless charging is more aesthetically pleasing than having a cable connected to their device. Let’s go ahead with this ultimate guide to Wireless Charging Pads.
How Wireless Charging Pads Work
Wireless charging pads, like traditional chargers, connect to a USB port or a wall outlet. They generate an inductive or magnetic field within the charger’s coil when connected. When you place your smartphone or device on top of the pad, the coil with the charger wirelessly connects to the coil in your device’s battery, quickly and easily powering it. These chargers are compatible with virtually any Qi smartphone or tablet due to the electromagnetic field created and the resonance technology.
Types of Wireless Charging Pads
As mentioned earlier, there are three main types of wireless charging pads, each with its own characteristics and specifications. So, let’s dive in and explore the different types of wireless charging pads in more detail.
1. Qi wireless charging pads
Qi wireless charging is a new system that wirelessly charges devices through a process known as induction transfer. Instead of using a plugged-in cable or connector to connect the device to a plug socket or other electrical source, users simply place the device near a wireless charging pad.
2. PMA wireless charging pads
Power Matters Alliance, or PMA, is based on inductive charging, which works over short distances (less than 1cm) and typically uses magnets to keep your phone in place.
3. Magnetic resonance charging pads
A high-frequency oscillating magnetic field transfers energy between two coils functioning at the same resonant frequency in resonant wireless charging. The coils can be loosely coupled, but a high Q factor is required to maintain energy transfer over several centimeters.
Factors to Consider when Choosing a Wireless Charging Pad
Although the process of selecting a wireless charger is fairly straightforward, it’s essential to choose the right one. Here are some guidelines to help you make the correct decision.
- Check to see if your phone can be charged wirelessly. Because not all smartphones support wireless charging, make sure yours does.
- Look for a wireless charger that supports the Qi charging standard for maximum efficiency and compatibility.
- Consider the power wattage. The wattage of differing smartphones varies. While not all of them will support up to 10W for fast charging, buying a wireless charger that supports 10W charging is a good idea to be prepared for the future.
- Check how your chosen wireless charger connects to a power source. Is a wall adaptor included, or does it take power via micro USB or USB-C? It’s crucial to consider how you plan to connect it.
Advantages and Disadvantages of Wireless Charging Pads
While the convenience and ease of use offered by wireless charging pads are undeniable, there are several factors to consider before making the switch from traditional charging methods. In the following paragraph, we will explore some of the key advantages and disadvantages of using wireless charging pads and provide insights on how to choose the right one for your needs.
Advantages of Wireless Charging Pads
1. A strong touch of science and technology.
Wired charging necessitates dragging a long data cable, which is untidy and lacks any sense of technology. You only need to lean the phone on the charger for wireless charging gently, and the current will be continuously charged into the phone immediately.
2. More convenient to use.
Wireless charging mobile devices on the market primarily use the electromagnetic induction principle to achieve wireless charging. No interface is there between the charger and the device. The phone includes a receiving coil, and the charger includes a transmitting coil. It doesn’t matter what brand of phone you purchase; as long as it is compatible with the charging head’s wireless charging standard, it can be charged.
3. The interface durability is better.
Because wireless charging does not necessitate frequent plugging and unplugging of the charging cable, the wear and tear on the mobile phone’s data interface is greatly reduced. Simultaneously, the coil for wireless charging of mobile devices is not exposed to air, which can reduce oxidation and corrosion of the charging unit. The wired charging is frequently plugged and unplugged, which causes wear and tear, and the interface is exposed, making it susceptible to oxidation and corrosion.
Disadvantages of Wireless Charging Pads
1. The distance is too small.
Since the magnetic field decays quickly in the air, current mobile phone wireless charging technology has a very short distance, and the effective charging distance is only 3-8 mm. Considering the width of the charger + mobile phone protective cover + mobile phone case, mobile phone charging needs to be close to the charger to be effective.
2. There is electromagnetic radiation.
Because wireless charging of mobile phones is done through electromagnetic induction, the charger constantly emits electromagnetic waves. This electromagnetic wave has a frequency range of tens to hundreds of megahertz (MHz). Although it may not be as harmful to the human body as wired charging, it still can be more harmful than wired charging devices.
3. The price is higher.
Compared to wired charging, wireless charging requires both the charging head and the mobile phone to include a charging coil and related protection circuits. Simultaneously, a high-frequency wave circuit is required to ensure electromagnetic compatibility, so the overall cost is higher than with regular wired charging.
