    1. No short, decomposition to Portable Power Station 300W P03S and throwing into the fire;
    2. It is not allowed to dismantle the charger and battery without permission to transform them;
    3. Do not adjust the output voltage to be higher than the equipment voltage, otherwise the equipment may be damaged;
    4. Pay attention not to heavy pressure, fall, strong vibration, rabbit caused by short circuit phenomenon, resulting in short circuit detonating when charging;
    5. Use and store under the condition of ventilation, room temperature and dryness, and do not use and store in overheated and humid environment;
    6. For the product heat dissipation space, reserve 5CM space around the product to make heat dissipation convection;
    7. When the power of the product is insufficient, the load power exceeds the rated power or the ambient temperature is too high, the product will automatically start the protection function to close the output;
    8.  Power charging, it is recommended to charge without load;
    9. The power supply itself will be exhausted if it is not used for a long time, please make sure to charge it every 6 months;
    10.  When using AC load, the power provided by this product is the rated load power. Generally, the AC load device with less than this power can be used normally. However, some electrical equipment often starts with a power greater than the rated power when it is turned on, such as the moment when the motor equipment starts. The power is generally several times the rated power. In addition, the starting power of energy-saving lamps is about dozens of times of their rated power. If their starting power is greater than the peak power of our products, the overload protection function of our products will be activated, and the output will be automatically turned off;
    11. It is forbidden to use this product in the environment of gasoline, gas and other flammable, explosive and corrosive gases;
    12. The product has accidentally entered water or other foreign substances. In order to ensure the safety of the product, please send it to the distribution office for testing and processing. Due to abnormal use, the company will charge according to the actual situation.
