Advantages and disadvantages of wireless charging

Wireless charging is a very meaningful development and research direction. We all know that there are many hidden dangers in wired charging, and wired charging is greatly affected by distance and environment. Sometimes we need to connect a lot of wires for charging, and some wires are not safe, but we will still use it for charging.

Every year, there are some news about the fire caused by connecting wires illegally. However, as long as there is wireless charging, these situations will not happen again, and we will no longer need to connect lines for charging in the future. As long as the equipment to be charged is near the wireless charging board, it can be charged. It's very convenient and safe. In this way, there will be no exposed plug outside, and there is no need to worry about a child touching the charging plug leading to electric shock and death.

And the wireless charger is waterproof. Some of our charging plugs can't touch water, or they will leak electricity. But the wireless charger is waterproof, even if it leaks water on it. In this way, we can eliminate some security risks and make our life safer.

Another advantage of wireless chargers is that they don't have to worry about adaptation. Wired charger different items, different brands of its charger plug is not the same, an item can only use their own charger. But when we have more things, it's not convenient. There are charging wires everywhere. It's not only troublesome, but also can't be shared after damage. We have to replace them. Now the charging line is also more expensive, so it would be much better if all the charging devices were replaced by wireless ones. There is no need to worry about the damage and loss of the charging line.

Of course, everything has two sides, and wireless charging has its disadvantages. The wireless charging board is inefficient. According to the design and the location of the user's mobile phone on the charging board, the charging efficiency may be between 30% and 80%. That is to say, even in an ideal state, 20% of the electricity will be wasted.

Although charging efficiency has been improving, the efficiency of low-power charging (such as mobile phone) is lower than that of high-power charging (such as electric vehicle) - the efficiency is close to wired charging.

Therefore, the disadvantage of wireless charging is mainly reflected in its efficiency, and its power conversion rate still needs to be further improved. In this way, there will be no waste of electric energy.
