It may be that the output voltage of the charger is insufficient or there is a problem with the plug or wire. Change the charger with the same voltage value, or re-solder the plug and replace the wire. Charging port Faulty Is there a problem with the port on the fan? It can also cause the charge to fail. Replace the charging jack directly, or solder the pin with a soldering iron. Battery aging After a long period of charging and discharging, the battery performance may deteriorate. According to the model specifications for a new battery, generally 7V18650 battery.
The charger itself is damaged, although there is an indicator light, but the output voltage of the charger is not or the plug and wire are disconnected, resulting in failure to charge the batteryIf the battery is not charged, the motor cannot be started naturally. If the charging port on the small fan is faulty and there is a circuit break, the battery cannot be charged. Rechargeable battery due to a long time of charging, discharge, resulting in poor performance, loss of charging ability.
General charging small fan how to charge the following situations: the charger (power adapter) is broken or the charging cable is broken. The rechargeable battery fails due to long-term power loss. The power board is damaged (mostly the rectifier circuit diode is damaged). There is an open circuit fault from the charging port to the power rectifier circuit board.
The small fan cannot be chargedThe charger itself is damaged. Although the indicator light is on, the output voltage of the charger is not, or the plug or wire is disconnected, so the battery cannot be charged. If the battery cannot be charged, the motor cannot be started; Otherwise, the motor cannot be started.
indicates that the battery in the small fan is broken and cannot be charged. It can only be powered by an external power supply. First, because the power adapter may fail, it cannot transmit electricity to the small fan. The second is the poor contact between the charging cable and the small fan, and many times there will be bending at the interface between the wire and the small fan, resulting in poor contact. Third, power supplyThe fault of the board itself, which is basically the fault of the rectifier circuit bipolar plate.
During the working process of the charger, the internal components will be stressed, and 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.
If you are doing wireless charging, as in wireless transmissionPort, or solder the pin with an electric soldering iron. Battery aging After a long period of charging and discharging, the battery performance may deteriorate. According to the model specifications for a new battery, generally 7V18650 battery.
General charging small fan how to charge the following situations: the charger (power adapter) is broken or the charging cable is broken. The rechargeable battery fails due to long-term power loss. The power board is damaged (mostly the rectifier circuit diode is damaged). There is an open circuit fault from the charging port to the power rectifier circuit board.
The charger itself is damaged, although the indicator light is on, but the output voltage of the charger is not or insertedThe head and wire are disconnected, resulting in inability to charge the battery, and the battery cannot start the motor if it is not charged. If the charging port on the small fan is faulty and there is a circuit break, the battery cannot be charged. Rechargeable battery due to a long time of charging, discharge, resulting in poor performance, loss of charging ability.
2, under normal circumstances, the charging fan can be used while charging. However, the following points should be noted: The working time and charging time of the fan: Different models of charging fans have different working time and charging time. If it is charged at the same time while working, it may affect its life.
3. No. Charging mini fan using improper or poor quality battery or charging cableCan cause circuit failure, serious can cause explosion. The cause of the explosion is: the battery itself. Due to internal defects in the battery, the battery itself explodes without charging or discharging. The battery cell is overcharged for a long time. Lithium batteries in special temperature, humidity, poor contact and other conditions or environments may be instantaneous discharge to generate a large amount of current, resulting in spontaneous combustion or explosion. It's short.
