Quality Components Compar​ison

Question 1,Why the tire pressure stop at 2.4 Bar (35psi) ? My car need 2.8 bar or 3.2 bar.Answer,B31A tire inflator have pre-set tire pressure function, the default preset pressure is 2.4 Bar.
When the pressure reach 2.4bar,it will auto-stop inflation.
We can change the preset pressure as below step,
1.To set the target pressure, press and hold the “+”or “-” button until the LCD flashes.
2.Continue to press “+”or”-” buttons until your target pressure is reached.
3.The LCD will continue to flash for a few seconds and then stop automatically.
4.This means your pressure has been set OK now.Question 2,

Why the tire inflation speed is not so fast?

When the compressor working, it needs 100W (12V 8A) power supply.
We suggest to start the engine of your car before you inflate the tire.
1. This will ensure that there is enough power supply.
2. This will faster the speed of tire inflation.
3. Protect your car battery.
Especially in winter,the activity of car battery decreased,the battery can not provide enough power for tire inflation.

Very satisfied with the compressor. It's very good that you can see the pressure before starting. Screen is very visible in daylight and so in the dark because it's back lit. Light is not so bright at day light, but does it's job in the dark. Quality is okay i'd say. Mine dropped one of the rubber feet but i don't mind a about it that much. Tested this on my Volvo and there i put 280kPa. Worked with no issues. This compressors wasn't as noisy as i thought which was positive surprise for me. I thought it would be like those blowers that you use on inflatable toys but this is a lot quieter. This comes with a nice bag so you can throw it in the back of you car. Seller sen't this very fast so i'm very satisfied with the store.
