Main Features: -Long Life Battery: 8000mAh Large Capacity Battery, lasting for 120 days.  -Low Energy Consumption: 15min live oxygen release, 15min rest and wait for the smell to be removed,monitor current and battery status, and dynamically adjust power supply.  -Live Oxygen Deodorizes: The state-of-the-art living oxygen technology reacts with bacteria-containing hydrogen sulfide and ammonia odor gas through the principle of intensifier oxidation, inhibits catalysis, and completely eliminates bacteria.  -High Voltage Frequency Conversion Sterilization: The machine ionizes the air at high pressure, releasing high concentration of active oxygen molecules, killing harmful bacteria, and eliminating various peculiar smells caused by food accumulation.  -U-shaped Angle All-round Sterilization: U-shaped active oxygen release path, which  transports active oxygen to every corners of the refrigerator, and sterilizes every corners.  -Concealed Airfoil Fan Outlet Can Isolate Water Vapor: Mr. Bang's powerful oxygen purifier has a hidden and built-in lead flow design. Even if the water vapor condenses, it can drip naturally, which is safer.  -Black Acrylic Cleverly Embellished Fiber, Fine-hole Extinction Sensor: When the  refrigerator door is opened, the light is on and the release of active oxygen stops. When the refrigerator door is closed, it will continue to work after an interval of 5 minutes.  -ABS Excellent Material, Anti-freeze and Moisture-proof: The body adopts stable performance and antibacterial ABS polymer material, which has high strength, good toughness, anti- corrosion, heat insulation, and wear resistance.    Specification Material: ABS+Acrylic;  Color: White;  Rated Voltage: DC5V;  Working Humidity: 25%-60%RH ;  Power: Normal 0.5W/Enhanced 1W;   Applicable Area: 1.6m;   Working Time: 120 Days;  Standby Power Consumption: 3mW;  Working Temperature: -30-50°C;  Power Supply: Type-C Charging;  APP Control: Yes(Smart Version)/No(Deodorant Version);  Battery Information Battery Type: Li-ion battery;  Battery Capacity: 2500mAh(Deodorant Version)  8000mAh(Smart Version);  Dimension Product Weight: 0.54 kg ;  Product Size (L x W x H): 13.80 x 13.80 x 6.80 cm;     Package Contents 1 x Refrigerator Deodorizer,  1 x USB Cable,  1 x Manual
