Xiaomi Portable Electric Air Compressor 2 – 150 PSI Cordless Tyre Inflator, 2000mAh Battery, 6 Preset Modes, Auto-Stop, USB-C

The Xiaomi Portable Electric Air Compressor 2 is a cordless pump about the size of a large phone that tops up car tyres, bike tyres, e-scooter tyres and balls without a wall socket or a 12 V lead. You set the target pressure, attach the hose and press start; it stops on its own when the reading matches, with Xiaomi quoting ±1 psi detection accuracy. It weighs about 490 g, reaches up to 150 psi (10.3 bar) and charges over USB-C, which makes it an easy thing to keep in the boot of the car or in a camping box for desert trips.

What the Xiaomi Portable Electric Air Compressor 2 does well

Most drivers only need a pump for a few minutes at a time: a tyre that dropped overnight, a pressure check before a long drive to Fujairah, or lower pressure for sand and back up again on the tarmac. For that pattern, a small battery pump that remembers your settings is more convenient than a petrol-station air line. Xiaomi says one full charge can reinflate up to ten 205/55 R16 car tyres from 2.0 to 2.5 bar, which is a typical top-up.

From completely empty the job is bigger. Xiaomi’s figure is about 8 minutes to fill one empty 205/55 R16 tyre from 0 to 2.5 bar, and it says one charge can fill two such empty tyres in a row. A road-bike tyre (700c) goes from 0 to 120 psi in about 86 seconds. Both figures were measured at 25 °C ± 2 °C, so expect longer times on a hot UAE afternoon when the unit has to rest between runs.

Six preset modes and the dot-matrix display

The Xiaomi Portable Electric Air Compressor 2 has five presets with sensible defaults and limits, plus a manual mode. Car starts at 2.5 bar (adjustable 1.8–3.5 bar), Motorcycle at 2.4 bar (1.8–3.0 bar), Bicycle at 45 psi (30–65 psi), Electric scooter at 50 psi (45–60 psi) and Ball at 8 psi (4–16 psi). Manual mode opens the full 3–150 psi range for road bikes or anything else that needs a specific number.

Xiaomi replaced the digital-tube readout of the first version with a dot-matrix display, which it says is easier to read in the dark, and the screen shows the active mode, the pressure in psi or bar, and a four-step battery gauge. A built-in light helps when you are crouched next to a wheel at night, and the hose has its own on/off switch so the pump does not start by accident in a bag.

Battery, charging and the valves it fits

Inside is a 2000mAh (14.4 Wh) lithium-ion battery. It charges through a USB-C port at 5 V ⎓ 2 A and takes about 3 hours; Xiaomi’s FAQ notes it does not support fast charging. Xiaomi rates charging between 5 °C and 40 °C and use between −10 °C and 45 °C, so do not leave it charging on the dashboard in summer.

The 200 mm hose ends in a Schrader connector, the valve type on cars, motorbikes and most scooters. In the box you also get a Presta adapter for road bikes, a needle adapter for balls, a quick-connect valve adapter, a storage pouch and a charging cable. Xiaomi rates the operating noise below 80 dB(A) at 1 m.

Xiaomi Portable Electric Air Compressor 2 or the 2 Pro?

Xiaomi also sells the Xiaomi Portable Electric Air Compressor 2 Pro, a separate model with a bigger 2500mAh, 27 Wh battery. The Pro is the better choice if you regularly fill tyres from empty or run a 4×4 with large tyres. The Xiaomi Portable Electric Air Compressor 2 on this page is the smaller and lighter of the two, and it is enough for routine top-ups, bikes, scooters and footballs.

Who This Is Not For

If you deflate large off-road tyres for dune driving and need to reinflate all four before leaving the desert, this pump will be slow and will need cooling breaks; Xiaomi warns the unit gets very hot after a long run. A 12 V compressor that plugs into the car, or the 2 Pro, suits that job better.

It is also not waterproof, so keep it out of rain and beach spray, and it cannot charge your phone: Xiaomi does not list a power-bank output. The display is not a touchscreen; all settings are on the physical buttons.

How long does it take to fill a car tyre?

About 8 minutes from 0 to 2.5 bar on a 205/55 R16 tyre, per Xiaomi’s test at 25 °C. A normal top-up from 2.0 to 2.5 bar is much shorter, and one charge covers up to ten of them.

Does it stop automatically?

Yes. You set the target pressure and the pump stops when it gets there, with ±1 psi detection accuracy according to Xiaomi.

Will it work on a road bike with Presta valves?

Yes. A Presta adapter is in the box, and the Bicycle preset or Manual mode covers road-bike pressures up to 150 psi.

Can I use it as a power bank?

No. Xiaomi does not list a USB output for charging other devices; the USB-C port is for charging the pump.

Is it the same as the 2 Pro?

No. The 2 Pro is a separate, larger model with a 2500mAh battery. This Compressor 2 is the smaller, lighter version.
