1. Although our 12V4A wall-mounted power adapter has stable performance and strong performance, it should not be used beyond the rated voltage and current range.

2. Please pay attention to the surrounding environment when using it, and be sure to do a good job of ventilation and heat dissipation, because any power supply equipment will definitely generate a lot of heat when working for a long time. If this heat is not dissipated in time, it will definitely cause safety hazards to the power supply and equipment. In addition, the shell will have a certain temperature during use. As long as it is not hot, it is normal to keep the temperature below 45°C. So we must do a good job of proper inspection. When the temperature of the adapter is too high, please stop using it and check the cause.

3. After the power supply is installed and connected, before starting work, please check whether the power supply or power cord is squeezed, and whether the plugs are connected stably. If not, please adjust to a suitable and stable state to prevent long-term squeezing and damage to the power supply or leakage and other safety hazards.

4. After the power supply starts working, it must be checked frequently. If it is found that the working environment of the power supply has changed after a period of time, such as long-term rain, the power supply and equipment have been working in a humid or even leaking environment, please change the working environment of the power supply in time. It is strictly forbidden to continue using the power adapter in a very hot or humid environment. Keep our power adapter working in a comfortable environment to ensure its optimal performance.
