Operating environment of lithium-ion batteries:
In a clean, dry, and well-ventilated environment with a temperature of 0~40℃ and a relative humidity of no more than 75%, it should be protected from contact with corrosive substances and kept away from fire and heat sources.
Charging Precautions:
This product must not be charged through the discharge terminal; it must be charged using the included dedicated charger from a charging socket. When the charging indicator on the charger stops scrolling, please remove the charging plug promptly to prevent overcharging.
Precautions for discharge:
The product has an overcurrent protection function. When the operating current of the electrical equipment exceeds the maximum output current of the product, the overcurrent protection circuit will activate, causing the electrical equipment to appear to malfunction.
Precautions for daily use:
The discharge terminal output is not controlled by the switch on the panel; it only shuts off when the battery voltage is below 9.0V. The switch on the panel controls the display and USB socket output. When the switch is on and the battery voltage is ≤9.1V, the display will flash for one second on and one second off to remind you to charge it in time. When the battery voltage is ≤9.0V, the display will turn off and the USB socket output will be turned off. This is to protect the lithium-ion battery from over-discharge. This is the process of the microprocessor on the control board entering sleep mode. You need to manually turn off the switch and turn it back on when the battery voltage is ≥9.1V to wake up the microprocessor, and only then will the display show the battery voltage value and the USB output be 5V.
