Features： 1、With multi‑protection, short‑circuit overload and over‑voltage protection, safe and harmless to the car. 2、The electric air pump with 4 switchable pressure units (PSI, BAR, KPA, KG / CM²), so you can set the tire pressure as desired. 3、The air pump will automatically shuts off when the set tire pressure is reached. The maximum pressure is about 150 PSI. 4、The LED light is translucent, which is convenient for special situations such as night inflation and tire changing. 5、Because it has no heat, long‑term output, intelligent control, can inflate your car automatically and fast. Specification： Item Type: Tire Inflator Material: ABS Battery Type: Lithium Battery Battery Model: 18650 Nominal Battery Capacity (Unit: MAh): 2000mAh (Delivered with Built-in Battery) Vehicle Power Supply: 12V Working Current: 1-5A Maximum Current: ≤5A No-Load Current: ≤2A Air Efficiency: Charge 1.95 Mountain Tires for 2 Minutes Battery Capacity: 2000MA 12.4V Emergency Luminous Flux: 80 Luminous Flux for 10 Hours Working Temperature: 0℃-45℃ Charging Method: Micro USB Charging Time: About 7 Hours Reachable Pressure: 150PSI/10.3BAR/1030KPA/10.5KG Fitment: Universal How to Use: 1. It will automatically turn on when it is powered on for the first time, the blue backlight will be on when it is turned on, and the LCD will display the actual pressure value after 1 second. 2. Long press the power button to turn on/off, the blue backlight will be on after turning on. The air pressure unit is the air pressure unit when the machine was turned off last time. Short press the power button to cycle through the air pressure units, and short press the setting key to view the set target air pressure value. In this mode, press the SET key to set the target value cyclically. After viewing or setting the target value, there is no button operation and the actual air pressure value will be displayed after 3 flashes, or the actual air pressure value will be displayed after short pressing K1 once. 3. Setting values in four unit modes: a) Unit: PSI Range: 3.0PSI-150PSI Adjustable accuracy: 1.0PSI b) Unit: BAR Range: 0.2BAR-10.3BAR Adjustable accuracy: 0.1BAR c) Unit: KPa Range: 2.0KPa-1030 (display A03) KPa Adjustable accuracy: 10KPa d) Unit: Kg/cm² Range: 0.2Kg/cm²-10.5Kg/cm² Adjustable accuracy: 0.1Kg/cm² 4. There is no key operation or pumping operation in the middle of the machine after starting up (the detected air pressure value is less than 20 KPa) It will automatically shut down after 2 minutes. 5. The air pump can only work when the air pump switch is pressed in the actual air pressure display mode.
