How to read 2.5 on a car air pump?
1 Answers
Look at the black numbers, usually it's 2.5 bar. 1. Power supply from the car: Generally, car air pumps draw power from the car's 12V cigarette lighter socket, but some car air pumps can also draw power from the battery. 2. Connect to the tire valve: Generally, the connection between the car air pump and the tire valve is threaded, which can greatly avoid air leakage at the valve connection. 3. Set the inflation tire pressure: Preset the inflation tire pressure on the tire pressure setting panel of the car air pump (there is a display on the setting panel, which can show the preset tire pressure value and the real-time tire pressure during inflation). 4. Start inflation: Press the inflation start button, and the car air pump will start inflating the tire. When the preset tire pressure is reached, the car air pump will automatically stop.
