In the current smartphone market, more and more mobile phones support wireless charging technology. In order to make the wireless charging function of mobile phones more effective, mobile phone manufacturers have launched wireless chargers matching with mobile phones. The power of wireless charging has also developed from 5W, 7.5W, 10W to 15W, 20W, and even upgraded to higher power. Xiaomi recently launched a wireless charger-Xiaomi vertical wireless charger (fast charging 20W). As you can see from the name, this wireless charger uses a vertical design. When the mobile phone is charging, the user can see the pop-up notification more intuitively, and it is also more convenient to handle the mobile phone. Of course, the biggest highlight of this charger is the built-in dual coil, which can be used horizontally or vertically.
Since the launch of Xiaomi 9, Xiaomi has opened a clear gap with other brands in the full scene fast charging experience. Wireless charging supports up to 20W power, and the charging efficiency is comparable to the wired charging of ordinary mobile phones. The recently launched Xiaomi 9 Pro 5G version supports up to 30W wireless fast charging, taking the wireless charging experience of mobile phones to a new level. But after all, the technology is too cutting-edge. Except that users of Xiaomi 9 Pro 5G can experience the new experience brought by wireless flash charging, other mobile phones cannot support it, and it is expensive and the market is niche. Therefore, this Xiaomi vertical wireless charger (fast charging 20W) can be said to be a product launched for mass market considerations.
Today, Tookfun will take you to experience this wireless charger together.
The product packaging continues Xiaomi’s consistent simplicity.
Unpack. The package contains a vertical wireless charger, a data cable, and a Xiaomi product manual.
The charging board of Xiaomi vertical wireless charger (fast charging 20W) is made of PC material, which is not easy to cause wear on mobile phones or other products that support wireless charging. The charger uses Type-C interface.
The bottom of the base also has a non-slip pad design to prevent the phone from slipping while charging.
It is worth mentioning that an LED light is designed on the bottom bracket, which will turn green in working state.
The internal dual coil design of the vertical charger. The mobile phone can be placed upright, which is convenient for timely checking the current battery power, watching live broadcast, etc .; it can also be placed horizontally, which is convenient for watching dramas.
The charging board height design is very delicate. The height is lower than the camera of most mobile phones, will not knock the camera of the mobile phone.
It should be noted that the Xiaomi vertical wireless charger does not have a built-in charging plug. It needs to be equipped with a charging plug with a minimum of 5V / 2A to use. According to the instructions: 5V / 2A adapter supports 5W wireless charging; QC 2.0 / QC 3.0 (18W and above) adapter supports 10W wireless charging; QC 3.0 Class B (27W and above) adapter supports 20W wireless flash charging. Of course, the premise is that your mobile phone must support high-standard wireless charging power.

2. The graph of the curve of the mobile phone battery level from 0% to 100%.
Xioami 9:
Use Xiaomi vertical wireless charger (fast charging 20W) to charge Xiaomi 9 wirelessly. After a short period of low-power pre-charging, the Xiaomi 20W wireless fast charge began to shake hands and entered the stage of high-power charging. The battery level rose rapidly; after 7 minutes and 46 seconds, the battery level reached 13.42%; after the temperature rose, the power decreased and the charge The speed slowed down; after 30 minutes, 38.62% of the battery level was charged; after 1 hour, the battery level was charged at 71.98%; after 1 hour and 49 minutes, the wireless charging was completed.
Xiaomi 9 charging power curve. 20W fast charging lasted 7 minutes and 46 seconds, and the actual input of the wireless charger was about 23W. After the temperature of the mobile phone rises, the power drops to about 13W. After an hour, the power gradually decreases until the end of charging.
iPhone 11 (система 13.1.2）:
Беспроводная зарядка iPhone 11 с помощью беспроводного зарядного устройства Xiaomi (быстрая зарядка 20 Вт). Успешное соединение беспроводной зарядки и iPhone 7.5 W; зарядка 19.46% за первые 30 минут; зарядка 37.29% через 1 час; зарядка 54% за 1 час 30 минут; беспроводная зарядка 3 часа 13 минут завершена.
График мощности зарядки iPhone 11. Как видно из диаграммы мощности, обновление до версии IOS 13.1.2 все поддерживает iPhone 7.5 W Quick Charge. Беспроводная быстрая зарядка длится около 38 минут; после того, как температура телефона повышается, мощность колеблется от 5 Вт до 9 Вт; колебания сохраняются до 2 часов и 14 минут, зарядная мощность начинает постепенно уменьшаться.
I also tested my AirPods Pro. When it is placed normally, it still can’t be charged, but it can be charged by standing it.
Conclusion
This wireless charger can be said to be tailor-made for the Xiaomi 9 series: it can charge 38.62% of the Xiaomi 9 mobile phone in 30 minutes, and it only takes 1 hour and 49 minutes to fully charge. Of course, compatibility with mainstream brands of mobile phones is also very good. Especially most of the recent wireless chargers that can support iPhone 7.5W, after the iPhone is upgraded to iOS 13.1 version, it can not successfully shake hands with 7.5W wireless charging, but only with 5W. Xiaomi’s wireless charger can still successfully handshake the iPhone 7.5W wireless charging, which shows that it is perfectly compatible with iPhone.
However, there are some shortcomings. Xiaomi vertical wireless charger (fast charging 20W) does not support 5V / 1A plug. I personally think that the tilt angle of the charging board is a little large, and it does not support multi-position adjustment to adjust the tilt angle.
For now, the price of wireless chargers on the market is generally high, and the price of vertical design wireless chargers is higher than that of tablet wireless chargers. In terms of product compatibility, this wireless charger from Xiaomi has done a great job, and the price of Xiaomi products has been very pro-people. It can be said that this wireless charger is a good choice for both Xiaomi users and iPhone users.
