is ideal for users to use in a fast-paced life. To sum up, HuaThe P40 is a smartphone that supports wireless charging and wireless fast charging. Users can use a QI-compliant charger to charge the phone, or Huawei's own 40W wireless fast charger for fast charging. This advanced technology brings users a more convenient charging experience, and also provides more possibilities for the use of mobile phones.
This technology uses the induced magnetic flux generated by the induction magnet between the mobile phone and the wireless charger. Then, this induced magnetic flux is converted into electricity, and the phone can be charged. You don't have to worry about it dying like a power bank,Therefore, it is really convenient when the phone needs to be charged, and the price is not very expensive. However, compared with the fast charge we usually use, the charging efficiency is still slightly worse.
Wireless charging technology is a thing proposed in recent years, so its products are not so mature, although it can be wireless charging, but the current maximum charging power is only 20W, charging speed is still very slow, relatively, the current mobile phone fast charging has been as high as 30W, in contrast, or wired fast charging is better.
First of all, due to cost limitations, the cost of the current wireless charger is stillMuch higher than ordinary chargers, and due to high maintenance costs, most mobile phone manufacturers did not focus on promotion. Secondly, it is because the power transmission loss is too large, which causes the charging rate of most wireless chargers to be lower than that of ordinary chargers.
The Mi 13 supports 67 watts of wired fast charging, which takes just 38 minutes to charge the phone from 0% to 100%. In addition, it also supports 50 watts of wireless fast charge, which takes only 48 minutes to charge the phone wirelessly. At the same time, it also has 10 watts of reverse charging capability, which can be easily charged for other devices. The Mi 13 has the Thepaper.cn built into its battery
