How Wireless Charging Works
It was mentioned earlier that wireless charging is cable-free, but it isn’t quite completely cable-free, because the charging pad will have a cable going from the outlet into it. However, a cable is involved differently, and we will explain how it works below.
Wireless chargers operate with the help of an electromagnetic power, which creates a bond between the charger and the device. The overall system consists of a charging pad, plate, pillow, pod, and the battery, which is connected to a power source by a cable. It is only the last stage of the charging process that is wireless. Just place your smartphone on the pad, and it will get charged with the help of electromagnetic waves.
Each part of the system possesses planar coils that are used to transfer energy from the charging pad to the battery. The electrical power is modulated in such a way that the charging pad and battery can communicate with each other, so this allows the charging pad to detect that a valid battery has been placed on it before transmitting its full power to the battery.
So, What’s the Point of Using Wireless Chargers?
Charging without using wires comes in handy, and if you have ever experienced an exploded charging cable, you will appreciate the longevity you will get from a static charger pad instead of plugging in and pulling out cables every day. However, that is not the only reason you should embrace wireless charging, there are other benefits too, and they will be discussed below.
Advantages of Wireless Charging?
- Convenience
The most significant benefit of using a wireless charger is the convenience it offers and the fact that you won’t have to deal with messy cords anymore. Things will become more straightforward, and all you have to do is to drop your phone on the charging station/pad.
Also, you won’t have to worry about where you left your cord or purchase different chargers. With wireless charging, you can choose to charge your phones simultaneously.
- Fast Charging
A wireless charger charges as fast as regular chargers. However, the speed of the charger extensively depends on the rating of the wireless charger. So, when purchasing a wireless charger, be sure to check for the rating of the charger. That way, you won’t end up with a charger that has a lower rating than what your smartphone supports.
- Protection from Wear and Tear
Wireless charging prevents wear and tear on the charging port of your phone. Damaged charging ports is one of the most common faults that smartphone users experience. However, the less you have to plug in and pull out a USB cord, the longer your smartphone will last.
- Reduce Damages
Plugging a smartphone directly into an electrical outlet means it is being exposed to electrical connectors, which can create sparks that can damage the connection, as well as emitting electrical shocks that can hurt the unknowing individual.
There have been several reported cases that showed how people were injured and killed due to improper use of cables or smartphones while still connected to an outlet. This direct exposure to electric sockets is one of the safety reasons wireless charger is a much safer option than its predecessor.
- Reduces Insecurity
When a smartphone is connected to a USB charger, the security of the smartphone’s data is at more breaching risk, especially in public places.
For example, smartphone chargers used by multiple people in places like restaurants, coffee shops, or airport can be unknowingly used to steal data from people’s smartphones. With wireless charging, however, this security problem has been completely solved. Since it’s one of the significant reasons, the technology was invented in the first place.
The Disadvantages of Wireless Charging
- Higher Costs
The cost of purchasing a wireless charger is higher than the cost of purchasing regular chargers of the same ratings. So, you have to pay more to enjoy the benefits of wireless charging.
- No Multitasking
You can not charge with a wireless charger and also use your phone at the same time. Using your cellphone means lifting it from the charging pad, and once you lift it from the charging pad, charging stops too.
This is unlike how you can charge and also use your phone while charging with regular chargers.
The Future is Wireless Charging
In all, wireless charging offers more benefits than disadvantages, and the benefits it provides makes wireless chargers worth every penny spent on it.
So, to purchase a wireless charger or not? Well, the first factor to put into consideration is whether your smartphone supports the use of this technology, then you can decide whether purchasing one is worth your money. But as with other things, you’ll never know how much you would love it until you take the plunge.
