1. Material: ABS2. Power: PTC model 800W, heating wire model 400W3. Voltage: 220V4. Frequency: 50Hz5. Current: 3.6A for PTC model, 1.8A for heating wire model6. Size: about 16.7x14.1x10.6 cm7. Weight: about 550g for PTC model, about 470g for heating wire modelFeatures:1. Surrounding flow warm current circulating constant temperature, rapid warming2. Warm up the local air in the house, produce convection effect of hot air rising and cold falling, driving the air in the house to circulate and heat3. Intensive thickened mesh cover can quickly generate airflow and generate heat quickly4. Low noise and silent fan blades, uniform air supply5. Heat-resistant material, safe and anti-scalding, faster heat dissipation6. It can be adjusted by 45 degrees up and down arbitrarily, heating can be achieved in every position, covering efficiency is higher, and the range is wider7. Anti-scalding grille to prevent accidental touch and scald8. ABS back shell, resistant to falling and not easy to break
