Feature 1With multiprotection, shortcircuit overload and overvoltage protection, safe and harmless to the car. 2The electric air pump with 4 switchable pressure units (PSI, BAR, KPA, KG / CM), so you can set the tire pressure as desired. 3The air pump will automatically shuts off when the set tire pressure is reached. The maximum pressure is about 150 PSI. 4The LED light is translucent, which is convenient for special situations such as night inflation and tire changing. 5Because it has no heat, longterm output, intelligent control, can inflate your car automatically and fast.Item Type: TireInflatorMaterial: ABSBattery Type: Lithium BatteryBattery Model: 18650Nominal Battery Capacity (Unit: MAh): 2000mAh (Delivered with Built-in Battery)Vehicle Power Supply: 12VInput Voltage: Charger 5V/3AWorking Current: 1-5AMaximum Current: 5ANo-Load Current: 2AAir Efficiency: Charge 1.95 Mountain Tires for 2 MinutesBattery Capacity: 2000MA 12.4VEmergency Luminous Flux: 80 Luminous Flux for 10 HoursWorking Temperature: 0-45Charging Method: Micro USBCharging Time: About 7 HoursReachable Pressure: 150PSI/10.3BAR/1030KPA/10.5KGFitment: UniversalHow to Use: 1.
