Xiaomi Air Compressor 2 review
Xiaomi Portable Electric Air Compressor 2
By Tom Calder
A compact, well-reviewed battery inflator that's quick enough for a genuine flat-to-driveable top-up and small enough for a glovebox or grab bag. It's honest value, though its ±1 PSI accuracy claim is the manufacturer's figure — we haven't seen independent lab verification.
- Best for
- Topping up car, bike, motorcycle and scooter tyres — plus balls and paddling pools — without running the engine or hunting for a 12V socket.
- Skip it if
- You need to fully air up large 4x4, van or trailer tyres back-to-back in one session

Researched, not used. We haven't used this product. This review is built from the maker's specifications, owner reports and our own sizing.
What we like
- Battery-powered — no engine running or 12V socket needed, and the battery is built in rather than a separate tool-platform purchase
- Genuinely portable: charges via USB-C, so it can top up from a power bank or laptop charger
- Digital display with preset modes and auto shut-off removes the guesswork of watching a gauge
Worth knowing
- Battery charge is finite — good for around 10 top-ups per charge, far fewer full inflations from flat, so it needs a USB-C recharge for repeated heavy-duty use
- Quoted ±1 PSI gauge accuracy and inflation-time figures come from the manufacturer/retailer listings, not independent lab testing

Our review
Xiaomi's Portable Electric Air Compressor 2 is a pocket-sized inflator with its own 2,000 mAh battery, a digital gauge and six preset modes from car tyres to footballs. Set the pressure, screw on the hose and it stops by itself. It is quick enough to top up a soft tyre and small enough for a glovebox, but it is not a workshop compressor.
What it is
Xiaomi gives an inflation range of 3 to 150 psi (0.2 to 10.3 bar) and a sensor accuracy of plus or minus 1 psi. The battery is 2,000 mAh, or 14.4 Wh, and charges over USB-C at 5V 2A in about three hours; no mains adapter comes in the box. The unit weighs about 490 g and measures about 123 by 76 by 46 mm, with a 200 mm hose.
It comes with adapters for Schrader and Presta valves, a needle for balls and a storage pouch. There is a built-in light, a four-segment battery gauge and a switch on the hose.
How fast, and how many tyres
Xiaomi's own laboratory figures, credited to HOTO, give about eight minutes to take one 205/55 R16 car tyre from zero to 2.5 bar. Topping up is the realistic job: from 2.0 to 2.5 bar it quotes about two minutes a tyre and about ten tyres on one charge. It says a full charge will fill at least two completely empty tyres.
Those are best-case numbers at about 25°C. Xiaomi rates it to work from −10 to 45°C but to charge only between 5 and 40°C, so on a frosty morning expect fewer tyres per charge. The maker gives no continuous run-time or cool-down limit, so give it a break between big tyres. Charge it fully before winter and again every few months, because a flat inflator is no help on a cold morning with a soft tyre.
The preset modes
Six modes cover most of a household's tyres. Car defaults to 2.5 bar and adjusts from 1.8 to 3.5; motorcycle from 1.8 to 3.0 bar; bicycle from 30 to 65 psi; electric scooter from 45 to 60 psi; ball from 4 to 16 psi; and manual from 3 to 150 psi for anything else. Check your vehicle handbook or the sticker in the door frame for the right pressure before you rely on the default.
How it compares
On the tyre inflators comparison the Bosch Easy Pump has the same 150 psi ceiling from a 3.6V, 3Ah battery. The Ring RTC4000 runs to 120 psi from two 2,500 mAh cells. Makita's 18V LXT inflators, including the DMP180Z, reach 121 psi and suit anyone already on Makita batteries. Xiaomi's selling points are the size, the USB-C charging and the preset modes.
Our verdict
Buy it for topping up car, bike and scooter tyres at home or at the roadside, and for getting a slow puncture to a garage. Skip it if you regularly inflate van, 4x4 or trailer tyres from flat: a 12V or mains compressor with more air flow does that without waiting. Keep it charged; our car emergency kit checklist covers the rest of the boot.

Who shouldn't buy this
Skip it if you need to fully air up large 4x4, van or trailer tyres back-to-back in one session — a mains or vehicle-corded compressor with a bigger duty cycle will cope better than a battery unit.
