While analogue gauges deliver reliable readings, digital devices are often more accurate because they can often provide pressure readings to the decimal point. They're also easier to read, meaning you're less likely to take an incorrect measurement. ft long length and led light】: this electric air pump has a 3000±100mm (10.1 ft) power cord and 500±20mm (1.7 ft) air hose long enough to reach each tyre comfortably. with a bright led light, it could be used very conveniently at night. the alert mode and sos mode light could also attract people nearby for help. Simply press "on/unit/off" button to turn on the tool, select the range, and automatically shut off in 30-40 seconds to save the power. gauge automatically resets when taking pressure, no need to calibrate or reset the device.but you can also calibrate manually. Old classification: MICHELIN Enduro, Desert Race > size designation based on the width of the tyre measured at the tread level

Built-in air compressor/inflator. An air compressor removes excess overfilled air in your tyre, while the air inflation mode will pump in air when your tyre is under-inflated.

Larger inflators include rechargeable batteries, which make them completely portable. These are a better option if you want to pump up, say, bicycle tyres, without having to wheel the bike next to your car. You may also need a larger inflator for tyres that need higher-than-average pressures, such as a larger van or campervan. What about extras? If you need to deflate your tyre, you have two options. You can remove the pressure gauge and carefully use a screwdriver to push the metal pin on the valve to release air. Or if you are using an analogue gauge, you can use the built-in deflator button to bring the pressure to the correct amount. Tyre pressures are typically between 30psi and 40psi (or 2 bar and 2.8 bar). How to test your tyre pressure Newly designed high-precision tire pressure gauge with 0.01 two-digit decimal display, in addition to temperature and atmospheric pressure detection function, built-in battery, rechargeable, automatic calibration, self-illuminated screen, type-c interface

Size is probably the most important thing. The smallest inflators are around 20 x 20cm, so you can leave them in your car without losing too much luggage space. The best don’t skimp on the length of the power lead and air hose, which makes it easier to reach all four valves. Most can be preset to stop inflating when your tyre reaches the correct pressure.
