The power is related to the use method. The power of all PTC products is not a fixed value, but within a range. The power range of this fan heater is within the range of ±20% of the marked power. The power of the same product is different for different use methods. In short, the better the heat dissipation, the greater the power 2. The wires of the heater and the fan can be connected to the power supply separately, the fan must be DC input, and the PTC heater has no AC or DC. 3. The wires used by the heater are all high temperature resistant silicone wires, with a temperature resistance of >200℃; red positive and black negative 4. Due to the temperature limit of the fan, the heater is suitable for the ambient temperature of -5℃-65℃ Package List: 1 x Air Heater Note: Please note that the fan blades of this product will be sent 7 pcs or 9 pcs randomly, and make sure you will not mind before ordering.
