With a powerful magnetic motor, an empty tyre can be inflated in just 8 minutes. More powerful inflation. Hardware configuration upgraded, energy efficiency improved. It can continuously inflate up to 10 tires when fully charged, and fill two empty tires continuously. Switch between 6 modes, and the default air pressure range is limited to avoid over-inflation. The free mode can memorize the pressure value, set it once, and bid. Set the desired air pressure value or select the preset mode, one-button inflation, and inflation will automatically stop when it's complete. You don't need to watch over it, and it's effortless and convenient. The air pump adopts a 19mm high-precision alloy casting cylinder body, and the inflation pressure can reach up to 150psi. It takes only 86 seconds to fill a high-pressure bicycle tire.Pre-set pressure stops automatically and accurately displays real-time tire pressure., Manufacturer: WAFOHSR
