Description: Product Name: Indoor Heater Power cord length: about 1 meter Power: 500W Rated frequency: 50Hz Usage scenarios: study, dormitory, office, etc. Product size: 100*75*155MM Specifications: 1. [Three seconds to heat up]: It is hot when you open it, and the temperature rises quickly. We do what you want 2. [PTC ceramic heating element]: no open flame in the working environment, low working temperature, self-controlled constant temperature function, long service life, high efficiency and energy saving, quiet and noiseless work 3. [Convection air duct design]: Convective air duct design and air inlet design, take care of every detail of the airflow passing through, and reduce wind noise as much as possible on the basis of ensuring smooth wind 4.[turbine wind wheel has high wind power]: the turbine air duct is designed, and the thermal structure is optimized to make the air duct present a vortex shape, so that the thermal effect air volume is larger and the air supply distance is longer. 5.[Flame retardant material]: High temperature automatic power off, when the temperature is too high, it will automatically cut off the power supply, the body is made of flame retardant material, bid farewell to potential safety hazards Package Included: 1*heater
