What do you need to know to buy a wireless charger
2019-11-21 11:26:47

Do you know how to choose your wireless charger? What do you know about buying a wireless charger?

The first is to recognize Qi standard.

At present, there are two international mainstream industry standards for wireless charging. One is the Qi standard of wireless charging Alliance (WPC), the other is the air fuel alliance. These two standards have unified regulations on the performance, technical parameters, compatibility and safety of wireless charging products, and have strict certification standards.

Qi wireless charging standard is a very mature standard, which was implemented as early as 2008. Now many Android phones use this standard on the market.

The charging mode does not need any wires, and the mobile phone device can be charged directly by putting it on the charging pad.

And now many mobile phones and wireless chargers are this standard, so that you can use this charger no matter what you are. Even if you change your cell phone later, you can still use this charger.

And try to choose a charger with more than 10W power. No matter what we do now, we pay attention to efficiency. We all know that the wireless charging speed is relatively slow. Now wired charging has already been fast charging. But it will take a few hours for wireless charging to be fully charged.

In the future, one of the development directions of wireless charging must be to improve the charging speed. So it is necessary to buy a charger with high power.

When you buy a wireless charger, you must choose a charger with controllable temperature.

There will be a certain loss of electric energy in the process of wireless charging. This part of electric energy converted into heat will keep the mobile phone and wireless charger warm. The high-quality wireless charger can control the temperature below 40 ℃, which belongs to the normal range if it feels warm. And the temperature control function of the wireless charger can make the charger automatically cut off the power when the temperature is too high.

There is also a good wireless charger, its cooling function is certainly better. Cooling equipment can also be the standard of our choice.

When we buy wireless chargers, we can also choose some professional brands produced by large factories. In this way, it is more secure.

The principle of wireless charger seems simple, but its performance is very exquisite. There are not only differences in charging efficiency, charging speed and charging temperature, but also differences in induction sensitivity, stability, safety, durability, overvoltage protection, foreign matter detection and other aspects of performance.

Products with prices as low as 30 yuan can also have basic wireless charging functions, but the performance and quality are much worse. The charging experience is greatly discounted, the service life is relatively short, the damage to the mobile phone is relatively large, and even there are certain security risks.

Therefore, when we purchase, we still have to choose the brand with quality assurance. In this way, it can be used safely.

Finally, it's the price. How much is the right price?

Rich people want to buy mophie and Belkin wireless chargers that are already on the Apple website. There is no problem with this choice, after all, it is a personal hobby and choice.

But in fact, in terms of charging speed, beauty design and other aspects, Apple's wireless charger is not much different from the third-party brand's Qi wireless charger of about 100 yuan.

So the price of conventional wireless charger is about 100 yuan. Of course, it has higher requirements for size, beauty and innovation, and the price will be higher.

The structure, principle and material of wireless charger are not complicated. So its cost is not as high as we think.

When choosing, we should mainly consider from the above aspects. It doesn't need to be too expensive, but we can't choose the cheap products of those small workshops.
