Points for Attention in Using Mobile Phone Chargers

2019-7-8      View:

Driven by mobile phone giants such as Huawei and Apple, the trend of wireless charging began to spread. Domestic and foreign manufacturers began to introduce wireless charging in their flagship new products. In 2018, wireless charging will undoubtedly become the focus of the mobile phone industry, and the wireless charging market will accelerate its development.

According to the data, the application rate of wireless charging in smart phones is expected to rise to 60% by 2020, and more than 1 billion smart phones will adopt wireless charging technology. The number of smart wearable devices equipped with wireless charging is expected to exceed 200 million by 2020, and the market scale of wireless charging is expected to exceed 10 billion US dollars.

When it comes to mobile phone devices supporting wireless charging function, we will think of Huawei, Apple and other mobile phone giants, because under their leadership, more mobile phone manufacturers will quickly follow up the wireless charging function and accelerate the development of the wireless charging market.

Wireless charging technology is getting closer and closer to us.

In some restaurants, hotpot restaurants or cafes, a small area like an induction cooker at first sight has been added to the table, and that is the wireless charging device.

At present, the world has a unified wireless charging standard, which is called "Qi". It was formulated by many companies in 2012. The advantage of Qi standard is, of course, universal. It is just like our common USB slot. You don't need to consider what brand your mobile phone is and what brand your cable is. As long as it looks like USB at a glance, you can definitely use it when plugged in.

Qi is also the same. As long as the charger and equipment have the word Qi on their packaging, it means they are compatible with each other.

However, compatibility often means conservatism. Currently, equipment supporting Qi wireless charging standard has only 5V2A, that is, 10W power, and charging speed is very slow. A 3000mAh cell phone is fully charged, which takes at least 3 to 5 hours.

Therefore, some mobile phone manufacturers have developed a set of standards on the basis of supporting Qi standards. For example, Apple raised the wireless charging voltage to 7.5V, Sony 9V and Huawei 10V. The charging speed of these private standards is certainly faster, but the problem is that they are not compatible with each other.

When purchasing wireless fast charging products, besides charging speed, the first consideration is safety.

We know that mobile phones with wireless charging have almost no metal back cover. Because the metal will be heated rapidly in the process of wireless charging, forming a potential safety hazard.

Therefore, the wireless charger must have the function of detecting metal foreign matters. It can identify whether the mobile phone is placed on it or not. Only in the case of a mobile phone can it be charged.

The most common type of wireless charger on the market is pad type, which is relatively cheap. However, the mobile phone needs to be properly placed to start charging, and a slight offset is not acceptable. However, YMP wireless charger is designed with double coils. Any placement of the mobile phone will not affect the charging effect.
