For the first time, the author experienced wireless charging for mobile phones, which was released on the Russian mobile phone Yotaphone 2 in 2015.  At that time, I felt that the wireless charging function was very fresh. I bought a rectangular three-free wireless charger with a try attitude.  Originally, I was a little expectant. I didn't want to experience it but I was disappointed. Not only did I charge the turtle speed, but the wireless slow charge also took the angle. I had to play around to get the number.  Naturally, after using this wireless slow charge once, I never touched it again.

However, thanks to advances in technology, this type of wireless slow charging is no longer available on the market today.  Wireless fast charging is king. Its biggest advantage is that the charging speed is fast. With the charging, you can make full use of the piecemeal time to replenish energy to the mobile phone.

So, in the face of the market's dazzling wireless fast charge, how to choose?

1. The heat dissipation design is stressful

Wireless charging works by the principle of electromagnetic induction. Since it is a magnetic field cutting method, heat is inevitably generated.  Heat not only affects the efficiency of the wireless charger, but also transfers heat to the phone.  In order to better dissipate heat, it is necessary to use a metal material instead of a plastic material.

YMP Industry Limited 10w vertical wireless charging as an example, the entire body except the front (the front can not use metal, otherwise it will be detected as a foreign object by wireless charging and can not be charged), all made of metal aluminum alloy.  Not only that, in order to further improve the heat dissipation capacity, the heat dissipation holes are also dug on both sides of the back shell.

Of course, the advantage of the metal casing is that it is more stable and more durable on the table, in addition to facilitating heat dissipation.

2. The discharge curve should be smooth

The discharge curve is good so as not to hurt the mobile phone battery.  Good wireless charging has a smoother discharge curve during charging, and it is trickle charged when it is almost fully charged.

Of course, the above are just two important points to choose from wireless charging.  In the process of using wireless charging, don't forget to match the QC fast charging head, fast charging can make wireless charging faster and more efficient.
