• Safety, surface insulation.
• Heat up quickly, long service life.
• Self-control temperature
• Small sound

1. The power line does not distinguish between positive and negative, you can freely link power
2. When the heater is dry, low thermal efficiency, it is recommended to use with the fan.
3. It can be placed under a wet environment, but it can not be placed in water.
4. For the first time, It maybe produce a small amount of smoke, is a normal phenomenon, it will disappear within a short time.
5. Built-in 230 degrees Celsius heater chip, when dry the surface temperature of about 200 degrees Celsius, the fan blowing, the surface temperature of about 120 degrees Celsius.
6. Test: Ambient temperature 24 degrees celsius, the wind speed: 3.3 m / s, Hot air temperature is about 50-60 degrees Celsius when distance from the outlet is 10cm..
7. Under normal circumstances, PTC heater in a very short time after the start, it will have an impact power, which is about 1.5 to 3 times the rated power, but will rapidly decline, which is normal. Please buyers understand!
