Make sure the input voltage and the power should be within the range of the energy storage power supply. The life span will be prolonged if you use it properly. 2. The connection cables must be matched, because different load cables correspond to different equipment. Therefore, please use the original connection cable so the performance of the device can be guaranteed. 3. The energy storage power supply needs to be stored in a dry environment. Proper storage method can prolong the service life of the energy storage power supply. 4.If you do not use the product for a long time, please charge and discharge the product once every month to improve the service life of the product 5.. Do not put the device under too High or too low ambient temperature, it will shorten the service life of electronic products and make damage of the product shell. 6. Do not use corrosive chemical solvent to clean the product. Surface stains can be cleaned by cotton swab with some anhydrous alcohol 7. Please handle the product gently while using, do not make it fall down or disassemble it violently 8. There is high voltage in the product, so do not disassemble by yourself, lest it may cause safety accident. 9. It is recommended that the device should be fully charged for the first time to avoid inconvenience caused by low power. After the device is fully charged, the fan will continue to work for 5-10 minutes after the charging power cable is removed for standby heat dissipation (the specific time may vary with the scene temperature) 10. When the fan is working, prevent dust particles or foreign matters from being inhaled into the device. Otherwise, the device may be damaged. 11. After the discharge is terminated, the fan continues to work to lower the temperature of the device to a proper temperature for about 30 minutes (the time may vary with the scene temperature). When the current exceeds 15A or the temperature of the device is too high, the automatic power-off protection is triggered. 12. During the charging and discharging process, connect the device to the charging and discharging device properly before starting the charging and discharging device; otherwise, sparks may occur, which is a normal phenomenon 13. After discharging, please allow the product to stand for 30 minutes before charging to increase the life of the product's battery.
