1, milletThe 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.
2, if the millet charger is not charged or discharged, the indicator light flashes without reason, it may be an internal circuit fault, mainly short circuit or leakage, or other parts failure. Need to contact Xiaomi after-sales service for maintenance. When a light is on, it means that the charge is connected; When the four lights flash together, it means that they are charging; When the battery level is below 75%, the three lights are used togetherBlink; And so on. When all lights are on, they are fully charged.
3, this is a quality problem, indicating that the quality is not good, and the charging treasure is also the same voltage as the mobile phone battery. There is a DC_DC circuit inside to boost the 5 volt voltage so that it can be filled with useful products. Generally, the load current of poor quality is different, and the sound is different.
4, the current sound when charging, normal will exist, please rest assured to use it.
5, squeak, is the sound of the rectifier element, normal. Xiaomi mobile power supply is LG/ Samsung top lithiumSub cell, the latest USB intelligent control chip and charge and discharge chip of Texas Instruments. Due to the use of the latest USB intelligent control chip and charge and discharge chip of Texas Instruments, this mobile power supply has multiple protection functions, such as temperature protection, short circuit protection, input overvoltage protection, input anti-reverse protection and so on.
6, drop sound is the sound of current, charging treasure current sound is to show that the charging treasure in leakage, quality has been a problem, continue to use it may occur short circuit and cause an explosion, it is recommended to contact the manufacturer's after-sales customer service as soon as possible, apply for after-sales return processing, or apply for after-salesCharge 55w, plug it into the socket and buzz for a while, then stop ringing?
1, the maximum power of w wireless charging is 55w Millet wireless charging sound , generally cannot exceed the nominal value Millet wireless charging sound , usually can be plugged all the time, do not charge basically no much power consumption, but the summer is recommended to plug in when it is used, After all, the temperature is already high, and the equipment will be very hot if it gets a little hot.
2, the distance between the charger and the phone is too far. Xiaomi wireless charger requiredTo fit with the phone to charge normally, if the distance is too far, the light will always flash. The charger port is loose. The interface of the wireless charger must be correctly inserted into the power socket, and if the interface is loose, the light will always flash. There is a problem with the charger.
3, Millet wireless charging loud I started before millet 55w wireless charging has been using the 55w charging head of millet 11, and now with 67w words to perfectly trigger the maximum wireless charging power. It is also possible to use direct wired Mi 11. And get the head of this 67wThe compatibility of charging the laptop is also very good.
The reasons are as follows: There may be water vapor on the main board of the mobile power supply, resulting in the sound of a slight short circuit on the main board. Mobile power motherboard in the process of boosting the sound, but this sound is usually very small, almost inaudible. If it is a slight noise, it may be the sound emitted during the current transmission process, which is a normal phenomenon, and the user does not need to take care of it.
Personally think that it is related to charging equipment, millet80W wireless charging base built-in cooling fan, charging the default open speed wireless charging mode (feel the noise can be manually closed), we can hear the "buzz" of the fan in the process of charging, hand near the bottom of the wireless charging base, can also feel the cool wind blowing out of the fan. I hope I can help you.
Click on the phone Settings page, select Sound and Vibration, then select Advanced Sound Settings, you will see the system Sound and vibration keys. After clicking, turn off the charging sound effect.
Millet 100W wireless charger appearance packaging box is still black color, front middle is phnom penhThe sharp corner pattern is contrasted with the wireless charging shape, and the words of 100W above and below indicate that the wireless charging power of this product is a higher level, and the latest version of the Xiaomi logo is also used in the upper right corner. The back is affixed with a 100W wireless charging base package information sticker, and printed with wireless charging, data cable and charger schematic.
Some Samsung mobile phones support wireless charging function, to achieve the function requires a separate charging kit, wireless charging and wired charging effect is the same, but the wireless charging time is relatively longer, no impact on the phone.
1, the circuit is designed with a switching power supply, in which the switching transformer will make a squeaking noise, which is the sound of the magnetic core is not tight and the oscillation frequency is higher. 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.
2, 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 boost to about 5V, this process requires a booster coil, Xiaomi wireless charging sound big You hear the sizzling sound is it issued, a 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.
3, millet 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.
4, millet new wireless charging treasure exposure Millet wireless charging sound big : Analysis of the possibility of upgrade charging blogger @charging head network Weibo revealed that millet is about to launch a new wireless charging bank, its design uses a white appearance, in sharp contrast to the traditional black version, causing netizens to speculate on the 20W wireless flash charge version.
