1. Charging

1)You can connect the mains power to charge the product. Also you can connect the solar panel to charge the product. The LCD display panel will blink incrementally from left to right. When all the 10 steps are green and the battery percentage is 100%, it means that the product is fully charged.

2) During the charging, the charging voltage should be within the input voltage range, otherwise it will cause overvoltage protection or mains trip.

2. Frequency conversion

When the AC is off, hold down the "POWER" button and the AC button for 3 seconds to automatically switch to 50Hz or 60Hz. The normal factory setting is 60Hz for the Japanese/American and 50Hz for the Chinese/European.

3. Product standby and shutdown

1) When all output DC/AC/USB/ wireless charging is off, the display will go into hibernation mode for 50 seconds, and automatically shuts down within 1 minute, or press "POWER" to shut down.

2) If the output AC/DC/USB/ wireless charger are all turned on or one of them is turned on, the display will enter hibernation mode within 50 seconds, and the display will enter the steady state and will not automatically shut down.

Click the "POWER" button or the indicator button to turn on, and press the "POWER" button for 3 seconds to turn off.

Notice

1.Please pay attention to the input and output voltage range when using this product. 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 two months 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.
