In modern society, electronic equipment has become an indispensable part of our lives. However, when sockets are limited, we often worry about charging. To solve this problem, wireless chargers came into being. The wireless charger transmits electrical energy wireless wirelessly to the device through the principle of electromagnetic induction, which makes us get rid of the problem of the socket. This article will introduce the principles and types of wireless chargers and how to choose the appropriate wireless charger.
1. The principle of wireless charger
The wireless charger uses the principle of electromagnetic induction to charge. It consists of a transmission terminal and a receiving end. The transmission terminal transforms the power to high -frequency AC power through the power supply, and then transformed into an electromagnetic field by transmitting coil. The receiving end receives the electromagnetic field by receiving the coil and converts it into electrical energy to achieve charging. The principle of wireless charger is similar to equipment such as electric toothbrushes, mobile power supply, but it does not need to be connected to the device through the plug. Instead, it transmits electrical energy to the device through electromagnetic waves to achieve charging.
Second, the type of wireless charger
The wireless charger can be divided into two types according to the difference in the receiving end: electromagnetic induction and radio frequency.
1. Electromagnetic induction charger
The electromagnetic induction charger is the most common type of wireless charger. It interacts with the coil of the receiving end through the electromagnetic field generated by the transmission terminal to perform electrical energy transmission. The electromagnetic induction charger is suitable for charging the equipment such as smartphones, tablets, smart watches and other devices. Just place the device on the charger.
2. RF charger
RF charger is charged by high frequency radio waves. RF charger has high charging efficiency and can charge multiple devices at the same time. RF charger is suitable for charging of equipment such as electric vehicles, drones, etc., and can provide electrical energy for multiple devices at the same time.
3. How to choose the right wireless charger
When choosing a wireless charger, you need to consider the following aspects:
1. Charging efficiency
Charging efficiency is an important indicator of the performance of wireless chargers. Higher charging efficiency can charge the equipment faster and save charging time. Therefore, choosing a wireless charger with higher charging efficiency can better meet our needs.
2. Charging speed
The charging speed is also a factor that needs to be considered when choosing a wireless charger. Different wireless chargers have different charging speeds, so you need to choose a suitable charger according to your needs. Generally speaking, the higher the charger with higher output power, the faster the charging speed.
The compatibility of wireless chargers is also an important factor. Some chargers only support the charging of specific brands or models, while others support the charging of a variety of devices. Therefore, when choosing a wireless charger, you need to consider whether it is compatible with your own equipment.
The safety of wireless chargers is one of our important considerations. Some low -quality wireless chargers may have hidden dangers such as overheating and over -current. Choosing a brand reputation and guaranteed charger can ensure the safety of use.
In addition to the above points, prices and appearance are also factor that we need to consider when choosing a wireless charger. The most suitable charger is the best choice.
The emergence of wireless chargers solves our dependence on sockets and makes our home life more convenient. However, when using a wireless charger, you also need to pay attention to some matters:
1. Use the right charger
Different devices have different requirements for chargers. Using unsuitable chargers may cause poor charging effects or hidden safety hazards. Therefore, when using a wireless charger, you need to choose the appropriate charger according to the equipment requirements.
2. Avoid excessive charging
Although the wireless charger can automatically stop charging, it may affect the battery life of the equipment on the charger for a long time. Therefore, it is recommended to remove it in time after the device is fully charged.
3. Pay attention to the charging environment
The wireless charger also has certain requirements for the charging environment. For example, there should be no metal objects around the charger that interfere with charging.
To sum up, the emergence of wireless chargers makes our home life more convenient. When choosing a wireless charger, we need to consider charging efficiency, charging speed, compatibility and security factors. At the same time, pay attention to using the right charger when using a wireless charger, avoid excessive charging, and pay attention to the charging environment. Only by choosing a suitable and using a wireless charger correctly can we truly say goodbye to sockets and enjoy the convenience brought by wireless charging.
