01030502040607 Portable Power Station Cleaning and Maintenance Product Maintenance Cleaning Product Transportation and Storage Disposal of Batteries Common Questions 1. Can I use the product while charging? 2. Is the charger heating normal during charging? 3. Why does the fan start sometimes? 5. Why can't the charging equipment be used within the rated range of the product? 6. Can I take the outdoor power supply on board? 4. Why does the product shut down automatically during use? Our outdoor power supply supports charging while using, but it is not recommended to use it during charging, for it will affect battery life. Heating is normal for the charger during charging. Our standard charger meets the requirements of the national safety standard. Please use with peace of mind. Outdoor power supply is equipped with high temperature protection function and the working of the built-in fan is conducive to the heat dissipation of outdoor power supply, thus avoiding high temperature. Therefore, the fan will start automatically when the temperature reaches a certain set value during use, and there will be a mild sound. When the outdoor power supply stops or only uses the low-power equipment, the output will automatically shut down after the time set by the system so as to avoid unnecessary energy consumption when the user forgets to shut down. * The battery level is lower than 20%! Please charge it. * The starting power of some charging devices will be greater than the peak power of the outdoor power supply, or the actual operating power is higher than the rated output power of the outdoor power supply! Therefore, it is recommended to choose a power supply with a higher power. No, the outdoor power supply belongs to the lithium battery product. According to the regulations of airlines, passengers are prohibited to take lithium battery products with a capacity greater than 100Wh on board. Troubleshooting of Main Faults Charging failure No product output Sudden interruption of output SymptomTroubleshootingSolution Check that the product, adapter and mains supply are properly connected Good contact, adapter indicator light off The charging indicator light is on but charging fails Rule out whether it's a contact problem The adapter is faulty; contact the after-sales service personnel Contact the after-sales service personnel Connecting lines of equipment and product not inserted in place Check whether the corresponding output switch is turned on Low battery level of product The product is still not usable after the factors above are ruled out Contact the after-sales service personnel Check and debug the device connection carefully Open the corresponding output switch and the display screen will display the output power Charge the product The power of the electronic equipment in use exceeds the rated power of the product The output power is too low and the product automatically shuts down after several hours of use Automatic protection against overcurrent, high/low temperature and other conditions cuts off the output Please purchase the product with the corresponding power and contact after-sales service personnel for more information The automatic shutdown function is set. Please turn on the main switch to start the product. The product is equipped with 7 protection functions. If the output is shut down due to overcurrent or overvoltage, please press the button again to start it when the product is restored to normal.
