marevic Mini desktop heater, portable in winter, suitable for home, bedroom and office Fan Heater  (Black)

1. Use negative ions to purify the air and enjoy the oxygen temperature: After turning on the negative ion function, 3.5 * 106 ~ 4.0 * 106 negative ions will be generated per cubic centimeter, increasing "air vitamins". 2. Double safety, overheating/fuse protection: The built-in thermal fuse can respond quickly and automatically cut off the circuit when the temperature is too high. When the thermal fuse detects that the machine is not working properly and outputs an overheating signal, it will immediately cut off the circuit to effectively prevent accidents. 3. Rapid temperature control. When the temperature point is not reached, the resistivity is very low. Once the set temperature point is exceeded, the resistivity suddenly increases, causing the current to drop to a stable value, achieving the goal of automatic temperature control.
