Inflates cars, bikes, and balls, and lights up in the dark. The Xiaomi 2 Pro compressor is discounted to 1,274 CZK

The portable electric compressor from Xiaomi, which we recently tested, can easily handle inflating car or motorcycle tires or bicycle inner tubes. The Portable Electric Air Compressor 2 Pro model has been on the market for almost two years and has gained many fans during that time. Alza is now selling it for 1,274 CZK instead of 1,424 CZK as part of Black Friday, which was its price just before the promotion.

Quick summary:
✅ It makes sense if you want to inflate cars, bikes, scooters, and balls without a cable and without going to a gas station.
⚠️ Consider that it is noisy and not suitable for inflatable mattresses or loungers.
💡 At 1,274 CZK, this is the lowest price on Alza in the last year and, according to Heureka, also the best offer on the Czech market.

Inflates cars, motorcycles, and balls, and stops automatically

The compressor operates in the range of 0.2 to 10.3 bar (3 to 150 psi) and offers preset modes for cars, motorcycles, electric scooters, bicycles, and balls. Each has a default pressure that can be adjusted with buttons, and there’s also a manual mode for any desired value. Once the set pressure is reached, the compressor stops automatically, so you won’t overinflate the tire if the value is set correctly.

It is powered by a built-in 2,500 mAh battery, which you can charge via USB-C, meaning you can use a phone charger or charge it in the car. A full charge takes approximately 3.5 hours. According to Xiaomi, one charge can inflate almost four completely flat tires of size 205/55 R16, or top up sixteen from 2.0 to 2.5 bar. With dimensions of 15.2 × 10 × 6.3 cm, it easily fits in the trunk or the passenger compartment glove box.

In our test, it inflated a bicycle inner tube in half a minute

In our test of the Xiaomi Portable Electric Air Compressor 2 Pro, we were most pleased that even a complete beginner gets used to it quickly. Pressing the button with the red dot releases the hose and lights up the display, then you switch modes with the arrow wheel. Holding the same button changes units between bar and psi.

A volleyball that requires 0.3 to 0.4 bar was inflated in about 15 seconds. However, the preset mode for balls accounts for a pressure of around 0.6 bar, so it’s always worth checking the recommended value on the item itself and manually reducing the pressure if necessary. We inflated a bicycle inner tube with a Presta valve in about 30 seconds after attaching the Presta adapter, then the compressor turned itself off.

The rich packaging was also a pleasant surprise. In addition to the compressor, it includes a storage bag, a Presta valve adapter, a ball needle, a quick-release nozzle, and a 40cm extension hose, which comes in handy if the integrated 23cm one isn’t long enough. On the back, there’s also a powerful LED light that can flash SOS or shine red, and another smaller flashlight is located on top. You’ll appreciate both in case of a flat tire after dark.

Customers praise performance, but dislike noise and plastic threads

On Alza, the compressor has an average of 4.8 out of 5 from 141 ratings, and 94% of customers recommend it. Over 5,000 units have been sold, and the return rate is 0.89%. Buyers most frequently praise its fast inflation, simple operation, and battery life. One customer reported a battery drain of about one-third after inflating four car tires, while another customer reported about half for 225/40 R18 wheels from 1.0 to 2.5 bar. The red warning light also received praise several times.

On the other hand, some people complain about the noise and the plastic threads of the adapters, which they feel don’t seem very durable. Others point out that the compressor cannot release pressure, so you have to manually deflate an overinflated tire. Some also mind the size and weight, especially compared to the smaller Xiaomi model.

Not suitable for inflating mattresses

The compressor is designed for small volumes of air under high pressure. Inflatable mattresses, loungers, or pool floats require the exact opposite: hundreds of liters of air with almost no pressure. It is not suitable for these; the compressor would overheat, and you won’t find a corresponding nozzle in the package anyway. Furthermore, according to one customer, it cannot be used powered by a cable when the battery is dead, so it’s good to charge it occasionally.

For a one-day cycling trip, we probably wouldn’t take it due to its size and weight, opting for a hand pump instead. However, for a multi-day group expedition where a flat tire is more likely, it makes sense.

Fits in a car trunk

The compressor will be most useful for drivers who want to check and inflate tire pressure at home before a trip or after changing tires, and for families who use bikes, scooters, and balls. Those looking for the lightest possible pump for a bike bag will be happier with the smaller Mijia Compact Portable Electric Air Compressor, which Alza is selling for 849 CZK at the time of writing. At 1,274 CZK, it’s a practical helper that customers praise, and it hasn’t been available cheaper on Alza in the last year.

Do you carry your own compressor in your car, or do you rely on gas stations?
