Regarding mobile phone wireless chargers, the discussion in the digital circle has always been high, with both advantages and disadvantages. To this day, some people say that there is radiation in wireless charging. Although experts have not given a correct answer to this question, even if there is radiation, it can be ignored. There are several advantages of wireless chargers that have to be mentioned: (1) support charging as you put it; (2) the safety guarantee coefficient is large; (3) Slow charging speed, low battery loss and prolonged service life are the most important.

At present, there are many kinds of wireless chargers in the market, such as Huawei, Samsung, Apple, Meizu, etc., with different prices and different quality, which makes it difficult for consumers to make a choice. But among these brands, Xiaomi's wireless charging is the most competitive in the market. Some time ago, Xiaomi went on the market with a 20W wireless charger, which caused countless netizens to rob it. It is mainly due to its small size, ultra-high peak value and built-in cooling fan, which not only makes it easy to carry, but also keeps its normal heat dissipation while "supplying power" to the mobile phone.

Finally, in terms of price, only 14$ is sold. From this point of view, it is also in line with the cost performance standard made in China. However, the only "defect" is that the sales are too fast. Every time the sales are started, there will be a "run out of seconds", which makes many netizens wonder: Is Xiaomi playing hunger marketing again? This is not known.

Speaking of high cost performance, I would like to share with you a wireless charger I just bought. It can be described as "a combination of beauty and talent". This wireless charger is small and ultra-thin, and can be placed in a wallet for easy carrying. Its shell is made of toughened glass and aluminum alloy, which makes it wear-resistant and strong, and will not leave scratches even if accidentally dropped.

As for performance, the output power of this wireless charger can reach up to 10W, whereas the input power is 9V/1.67A, which is even higher than the current mainstream market equipment in some aspects. There are also built-in MCU chips and charging management chips. Simply put, they have over-current, over-voltage, over-temperature, over-power, short circuit, over-charging and other protection functions to prevent hidden dangers and only to create a good charging atmosphere.

What is even more commendable is that the induction distance can reach 8mm, and the battery life can be continued without taking off the protective case of the mobile phone when charging. With the foreign matter sensing function, if metal foreign matter is detected to approach during charging (e.g. key, iron sheet, needle, etc.), it will automatically stop working to prevent the occurrence of "conduction" and other situations and always put safety first.

This wireless charger can meet the needs of most consumers regardless of its design or performance. Moreover, the price only needs 8.5$, which is absolutely "friendly" to consumers like the author.
