Indukcinis šildytuvas 5-12V

It must be ensured that the working voltage is above 4.5V! Do not use dry battery power!
The width of the heated object should be between 1/3 and 1/2 of the inner diameter of the heating coil, and the maximum should not exceed 2/3!
The diameter of the heated object should be controlled within 20mm as much as possible. If the heating is too large, it will be difficult to heat up to red. After all, the power is limited.
Not dedicated to always-on operation. Heating coil should be allowed to cool down each 5 minutes. When heated, part of the heat generated by the heated object is transmitted to the heating coil. For a long time, the temperature of the heating coil is high. If the heating coil is connected to the terminal, the plastic part of the terminal will be melted! Therefore, it is best to solder the heating coil directly to the PCB during induction heating.
For long-term use, it is recommended to use a copper tube as a coil and cool it with water.
Blue LED power indicator can be monitored to check input power.
The reasons why the indicator light is off may be: 1. The line is not connected, and the power supply is not powered. 2. The board has component damage.
When the indicator light is dark, it should be that the power supply is insufficient and you need to replace the power supply with a larger power supply. Non-tap is more suitable for induction heating
