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. The brightness of the light is improved.It speeds up by approximately 25% to help you get out of trouble quickly.With a high-power magnetic motor, it can fill up one empty tire in just 8 minutes*. The inflation is more powerful.Inflation speed increased by approximately 25%.Battery life improvement. It can inflate up to 10 tires when fully charged. The air pressure sensor uses a digital chip, and the tire pressure detection accuracy can reach 1psi*.6 preset inflation modes make it easy for beginners to operate. 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 farewell to complex settings., Manufacturer: WAFOHSR
