Xiaomi Portable Electric Air Compressor 2 150 PSI Inflator

The Xiaomi Portable Electric Air Compressor 2 is a cordless inflator for car, motorcycle, bicycle and scooter tyres, as well as sports balls. It delivers up to 150PSI, displays pressure digitally and stops automatically when the selected value is reached. Its compact 490g body, rechargeable battery and built-in LED light make it practical for routine tyre maintenance and roadside emergencies.

Technical Specifications

Best Uses and Limitations

Drivers building a practical emergency kit can find additional Gadgets for Car, including jump starters, inverters and multifunction vehicle tools.

How It Performs in Real-World Use

Automatic Inflation Without Constant Monitoring

Select a preset mode or enter the required pressure manually, connect the hose and begin inflation. The compressor measures pressure in real time and switches off automatically when it reaches the selected target. This reduces the risk of accidentally continuing beyond the intended value.

Suitable for Routine Car Tyre Top-Ups

Xiaomi states that a fully charged unit can restore approximately ten passenger-car tyres from maintenance pressure or fully inflate about two empty tyres under its laboratory test conditions. Actual battery performance varies with tyre volume, starting pressure, ambient temperature and selected target pressure.

Compact Enough for Regular Carrying

The compressor weighs approximately 490g and does not require connection to a 12V vehicle socket while operating. It can be stored in a glove compartment, motorcycle case, backpack or outdoor equipment bag. It also complements other compact Camping Accessories used during road trips and outdoor activities.

Built-in Lighting for Night-Time Inflation

The integrated LED light improves visibility around tyre valves in dark parking areas or during roadside stops. For stronger long-distance illumination and emergency signalling, AS2 also offers dedicated LED Flashlights.

Which Inflation Mode Should You Select?

The correct pressure should always be taken from the vehicle label, tyre sidewall guidance, equipment manual or ball manufacturer. A preset is a convenient starting point, not a replacement for the manufacturer’s recommendation.

Xiaomi Air Compressor 2 vs BL01 Mini Bike Pump

Choose the Xiaomi model when car and motorcycle compatibility, a larger battery and multiple presets are important. The BL01 Mini Bike Tire Air Pump is more suitable for cyclists who prioritise minimum carrying weight.

Charging and Maintenance

The compressor charges through USB-C in approximately three hours using a compatible 5V/2A power source. A suitable charger or one of the available AS2 Power Banks can be used for recharging while travelling.

Allow the unit and air hose to cool after extended inflation sessions. Charge the battery periodically when the compressor is stored for long periods, and check its battery level before road trips. The device should not be exposed to water or stored inside a vehicle under extreme heat for extended periods.

What Is Included in the Box?

The package includes the Xiaomi Portable Electric Air Compressor 2, quick-connect valve adapter, Presta valve adapter, needle valve adapter, storage pouch, charging cable and user manual.

Is Xiaomi Portable Electric Air Compressor 2 Worth Buying?

This model is a practical choice for drivers, riders and cyclists who need accurate cordless inflation without carrying a large compressor. Its 150PSI capacity, six modes, automatic stop, rechargeable battery and compact design make it useful for both pressure maintenance and unexpected low-tyre situations.

It is an air compressor only and does not provide car battery jump-starting. Users who need both functions should consider a larger combination jump starter and tyre inflator.
