What is the reason for the power bank’s nuisance noise?
Mobile Charging Power has become an indispensable electronic device in daily life. However, sometimes, power bank batteries make a zipping noise when charging or using, which makes many users feel confused and uneasy. In this article, we will popularize the possible reasons for the rattling of power bank treasure to help you better understand this phenomenon.
First of all, the power bank treasure has a ringing sound is the energy storage inductor issued by the relatively slight, quiet environment to listen carefully to hear the words is normal. Charging treasure ringing may be due to the normal operation of its internal circuitry. Charging treasure internal usually contains a boost circuit, filter circuit, etc., polymer section voltage of about 3.7-4.2V, need to use the DC-DC inverter circuit to boost to 5V from the USB port output to the cell phone charging, boosting needs to be first let the DC power into a high-frequency pulse, and then use the inductor or transformer boosting, if the pulse frequency in the auditory range, there will be a noise, theoretically belongs to normal. Phenomenon.
Secondly, the power bank battery may be related to the aging or damage of the internal components. With the growth of the use of power bank treasure, its internal components may gradually age or damaged, resulting in unstable circuit work, thus generating noise. In addition, if the mobile power is in the process of charging or use by the impact or fall and other external forces, may also lead to internal components loose or damaged, and thus produce noise.
In addition, the power bank treasure ring may also be related to the packaging material. The internal circuitry of the power bank treasure is usually protected by certain encapsulation materials, such as paint sealing, epoxy resin, and so on. However, prolonged use and temperature changes may cause these encapsulation materials to loosen or deform, generating noise.
Finally, it is worth noting that if the power bank treasure makes abnormal noises during charging or use, such as the sound suddenly increasing or becoming harsh, then there may be a serious problem inside the power bank treasure. At this time, it is recommended that you immediately stop using the power bank treasure and contact professional maintenance personnel for inspection and repair.
To summarize, the reasons for the power bank treasure ringing may be multi-faceted. Under normal circumstances, a slight tinkling sound may be a normal manifestation of the circuit work; however, if the sound is abnormal or accompanied by other problems, we need to pay attention to it in time and take appropriate measures.
How to deal with power bank treasure nuisance sound
Though the nuisance sound is usually a normal phenomenon, in some cases, you can consider the following points to further confirm and cope with this phenomenon:
Check the appearance and performance of the power bank treasure:
-Observe the power bank for other abnormalities, such as case deformation and overheating. These may be signs of more serious problems.
Compare behavior while charging: – If you have more than one power bank treasure, you can compare their behavior while charging. If the other chargers don’t have a similar sound, then it may need further attention.
Contact the manufacturer or after-sales service:– If there are concerns about the safety or performance of the power bank battery, you can contact the manufacturer or after-sales service of the power bank battery to ask if there are any risks or seek advice.
Safety and precautionary measures
Although the nuisance sound from power bank batteries does not normally cause safety problems, the following suggestions may be considered to ensure safe use and prolong the life of power bank batteries:
– Regular inspection and maintenance: Keep your power bank clean and regularly check the condition of the connection cable and power adapter.
– Avoid overcharging and discharging: Try to avoid overcharging and discharging your power bank, which helps to minimize wear and tear on the internal components and possible sound generation.
– Avoid External Physical Damage: Avoid dropping or bumping the power bank battery, which may cause the internal electronic components to loosen or become damaged, which in turn may produce unusual sounds.
Overall, it is usually normal for the power bank to make a zipping sound during the charging process, which usually stems from the working characteristics of the internal electronic components. Users can use observation and common sense to determine if the sound is normal and take appropriate precautions to ensure the safety and performance of the power bank. If there are any unusual sounds or other abnormalities, it is recommended to contact the manufacturer or seek professional advice.
