1, may not be compatible, may not be enough power, change the line to try.
2. Poor contact of interface or data line. The charger circuit system consists of five parts a. Lithium core capacity indicator circuit The lithium core capacity indicator circuit is composed of voltage monitoring chips of XC61CC series.
b. Cell protection circuit The cell protection circuit is composed of three parts: overcharge protection, overdischarge protection and overtemperature protection. HAT2027, R5402 and self-restoring fuse build triple protection, which greatly enhances the safety of lithium core.
c. Charge management circuit The charge management circuit uses CN3066, which divides the charging process into four parts: trickle charging, constant current charging, constant voltage charging and maintenance charging, so that the mobile portable power can maximize the reserve energy.
DC-DC booster circuit DC-DC booster circuit adopts MAX1771 integrated chip, which can release the lithium core capacity to the maximum extent within the safe range to achieve the purpose of supplying power to a variety of digital devices. e. Function expansion circuit function expansion covers the common needs involved in outdoor activities, with emergency night lighting, outdoor anti-theft security alarms, camping mosquito repellent
The repeated start of the charging bank circuit may be caused by internal circuit failure or quality problems. The possible faults include silk circuit short circuit, bad battery, and unstable output voltage. In addition, the charging treasure input voltage is unstable, the charging rate is too large and other conditions may also lead to circuit instability and repeated startup. In order to avoid such situations, it is recommended to buy a reliable quality charging bank, and avoid overuse or overcharging when using it, while paying attention to the safety issues when using the charging bank.
When the charging current exceeds, the protection circuit of the charging bank starts continuously
