Good horse with good saddle, mobile phone wireless charger purchase

Mobile phone is the most used mobile terminal in daily life, Internet, games and even office can be completed on the mobile phone. The mobile phone relies on the battery to "drive", once the battery runs out, it must be charged. We usually use the USB cable to charge the mobile phone. On the one hand, the USB port is easy to damage, and on the other hand, the cable winding is very troublesome. In order to get rid of the shackles of the cable, many smart phones add wireless charging function, but this requires a wireless charger.

Shopping guide

The so-called wireless charger, which uses the latest wireless charging technology, the advantages of this charging device are obvious. If not limited by USB cable, it is convenient to charge anytime and anywhere; The incoming call can be answered freely, making the office convenient and fast. Just imagine, when we want to charge a mobile phone, we don't need to go to the annoying charger or socket, we don't need to connect the mobile phone with any power supply to charge it, and we don't need to worry that the mobile phone will be unable to turn on because it runs out of power. It can be said that the mobile phone wireless charging is within reach. Now many smart phones have supported the wireless charging function.

In principle, wireless charging uses magnetic resonance to transmit electric energy in the electric and magnetic fields between the charger and the device, while coils and capacitors form resonance between the charger and the device. Because the energy is transmitted by magnetic field between the charger and the electric device, and there is no wire connection between them, the charger and the electric device can achieve no conductive contact exposure. However, from the perspective of application field, wireless charging can be divided into low-power wireless charging and high-power wireless charging. Among them, low-power wireless charging is what we are going to talk about today, which is widely used in mobile phones, cameras, computers and other devices.

There are five mainstream wireless charging standards: Qi standard, PMA standard, a4wp standard, inpofi technology and wi Po technology. Among them, Qi is the "wireless charging" standard launched by WPC, the world's first standardization organization to promote wireless charging technology, which is characterized by convenience and universality. First of all, different brands of products, as long as there is a Qi logo, can use Qi wireless charger charging. Secondly, it has overcome the technical bottleneck of "universality" of wireless charging. Mobile phones, cameras, computers and other products can be charged with Qi wireless charger.

If the smart phone you buy supports wireless charging, you should first see if it is equipped with a wireless charger. If not, you need to buy one yourself. Before purchasing, you should check which wireless charging standards your mobile phone supports (such as charging standard, charging power and wireless fast charging), and then choose the appropriate wireless charger. Generally speaking, in addition to the wireless chargers attached to mobile phone brands, the wireless chargers launched by third-party manufacturers can be compatible with a variety of mobile phones.

Therefore, when purchasing a mobile phone wireless charger, you should see the compatibility of the products you choose. For example, if you use a Huawei smart phone, if you buy a Huawei wireless charger, it may only support the wireless charging of Huawei smart phones. If you want to charge different brands and models of mobile phones wirelessly, you have to choose the wireless charger launched by mobile phone accessories manufacturers. This product often supports the wireless charging of Huawei, Xiaomi, oppo and even apple.
