1, the charger in the working process, the internal device will be stressed, slight vibration is inevitable, so it will emit a sizzling sound, which is a normal phenomenon; The use of substandard chargers may also make Huawei mobile phones quickly charged as there isA noise occurred.
2, RPM. The built-in intelligent silent fan can adjust the speed of the fan intelligently during the day and automatically switch the ultra-silent mode at night. The built-in high-efficiency centrifugal fan can increase the air volume by 50%, and the innovative bottom three-dimensional air duct design can dissipate heat not only for the charger, but also for the mobile phone.
3, if you are wireless charging, because there will be energy loss in the wireless transmission process, and then produce a certain amount of heat, there will be a phenomenon of wireless charging heat, this is normal.
4, some of Huawei's high-end mobile phones in addition to support super cable fastCharging can also support wireless charging, the use of wireless charging requires a separate wireless charger. How to use Huawei wireless charger? Connect the charger (the charging tip that came with your phone or was purchased separately) to a power source.

2, the charger in the working process, the internal device will be stressed, slight vibration is inevitable, so it will emit a sizzling sound, which is a normal phenomenon; The use of unqualified chargers may also make Huawei mobile phones fast charging abnormal sound.
3, mobile phones do not support wireless charging, Huawei car wireless chargerSound Wireless charged noise , which is the magnetic core is not tight and emitted, the sound of high oscillation frequency. It's a transformer. They all make sounds just big and small. The squeak emitted by the high-frequency transformer is not loud and has no effect on the circuit and can be ignored.
The lithium battery of the charging treasure is the same as that of the mobile phone, most of them are 7V, such a voltage is unable to charge the mobile phone, so the charging treasure will increase the voltage to about 5V, this process requires the booster coil, the sizzling sound you hear is issued by it, and the better charging treasure may sound relatively small. The inductance on the mainboard of the charging bank occurs in the high-frequency electromagnetic resonance, which has nothing to do with it.
Mi charger. If it is wireless charging, sometimes he has some sound is very normal, so do not worry about this is also a normal phenomenon when he charges, if the sound is larger, you can go to the millet after-sales consultation to check.
For you who pursue individuality and safety, the youth version of Xiaomi wireless charging treasure is undoubtedly a better choice.

Xiaomi wireless charger green flashing is in the state of charging. The corresponding indicator relationship is as follows: Wireless charge noise : 0-30% orange light blinking 30-99% green light blinking charging completed green light steady on charging abnormal red light flashing fast Finally summarize: If the charging bank is charging red light blinking is abnormal; Charging bank wireless dischargeWhen the light flashes is abnormal; It is abnormal that the indicator is not on when the charger is discharged.
There may be a problem with your mobile phone or power bank. This charging bank supports a maximum speed of 30W, which can meet many charging power needs. It can also charge three devices at the same time, that is, a wireless, 2 USB wired charging, so that you can charge your friend's mobile phone is also very convenient. And you can charge it directly in the case.
1, like when the induction cooker is put on the pot, wireless noise , there is vibration hemp wireless noise feeling, there is a buzz. Low efficiency and high heat. Induction cooker plus cooling fan can be started. Wireless charger power will not do large, long charging time.
2, according to your description, the wireless charger will have a slight sound when working in a quiet environment. This is the sound of the transformer working. It's a normal phenomenon.
3, I think it is related to charging equipment, milletThe 80W wireless charging base built-in cooling fan, the default charging speed wireless charging mode is opened (feel the noise can be manually closed), we can hear the "buzz" sound of the fan during the charging process, the hand near the bottom of the wireless charging base, can also feel the cool wind blown by the fan. I hope I can help you.
2, personally believe that it is related to charging equipment, Xiaomi's 80W wireless charging base is built inHot fan, when charging the default open speed wireless charging mode (feel the noise can be manually closed), we can hear the "buzz" sound of the fan in the process of charging, hand near the bottom of the wireless charging seat, can also feel the cool wind blown by the fan. I hope I can help you.
3, and the current and voltage relationship. The constant sizzling sound comes from the inductor coil inside the mobile power supply. When the mobile power supply is external, it is necessary to start the inverter circuit, and the inverter circuit must produce a certain frequency of alternating current when working. This alternating current belongs to the audio range, and needs to be converted through the inductor coil to make a larger currentWhen used, the coil vibrates and transmits the resulting sound, resulting in a tiny squeaking sound.
4, click the phone Settings page, select sound and vibration, and then select advanced sound Settings, you will see the system sound and vibration keys. After clicking, turn off the charging sound effect.
5, this article will give you a detailed analysis of millet wireless charger green flashing causes and solutions. Green light flashing, charging in progress! The Xiaomi wireless charger flashes green, which is a signal that it is transmitting power to the device, indicating that charging is in progress. Flashing can also be a mystery even though the green light is flashing moreIn several cases, it means that the charging is normal, but there may be a problem with the connection between the charger and the device, or the device itself has some small conditions.
