🌞【Fast Heating, Quiet Operation】Our space heater uses advanced PTC ceramic heating technology, and the ultra-efficient fan allows this electric heater to heat more efficiently. It can heat up quickly in 3 seconds and stay warm for a long time. When working, the noise is less than 40dB, ultra quiet, which will not disturb your work or sleep. Perfect for staying warm during the cold winter. 🌞【ECO Mode, More Energy Saving】In ECO mode, you can set a precise temperature between 15°C-45°C. When the actual temperature is lower than the set temperature, the heater operates at a high heating level (high power); when the actual temperature is higher than the set temperature, it automatically operates at a low level (low power). This mode can effectively reduce energy consumption and save electricity costs. 🌞【All-in-one Fan Heater】This heater has 3 levels, natural wind (10W), low heat (900W) and high heat (1500W).
