🔋 Power Supply Recommendations
-
Use a 5V power source (switching supply, transformer, battery pack).
-
Ensure supply capacity > heater’s max power dissipation.
-
For multiple elements, connect in parallel to increase heating power.
⚠️ Usage Precautions
-
Do not use in flammable/explosive environments.
-
Avoid immersion in water.
-
Do not strike, puncture, or overlap elements.
-
Lower supply voltage slows heating but maintains constant surface temperature.
