I tried it. It works... Caution! Not more than 10-15 minutes so as not to overheat like all electric pumps

I have been inflating the basketball for a year once a week in the car. It works very well. It makes a lot of noise but it doesn't bother me. In a few seconds, it has inflated a ball.

Nice construction, easy to use. Suitable for inflating small dimensions. Suitable for car tires and balls.

I have used it several times. It may not be the fastest, but it does what it promises

I had to use it on a punctured tire with a large hole.
The truth is, I didn't believe it would fully inflate it.
In 15 minutes, the tire had the correct pressure and I was able to go to the vulcanizer to repair it.
Very good!!!
I highly recommend it!!!

In the positives, it has a very small size and fits everywhere. It also has good accuracy.
In the negatives, it takes time to inflate the car tires, you have to screw it in and unscrew it from the valve, and it makes A LOT of noise.
For emergency use, it's fine...

I have been using it for 1 year on car tires. Excellent product, small and fits everywhere. The pressure gauge actually works correctly, and the screw valve warms up without any issues. From 0 to 32 bar, it takes about 8-9 minutes depending on the size of the tire. In 6 months, the plug that connects to the battery broke, but I improvised by using crocodile clips directly on the battery and it works perfectly with the engine running. I highly recommend it, it's great value for money.

Somewhat weak and slow, when approaching the limits of the tire's air capacity, it delays a lot. I use it on a bicycle with 85 psi in the tires and on a motorcycle with 38 psi

for bicycle and ball that I used it is excellent.
very good the on-off and its small size!
Update.. in a car that needed help, it went from 5 to 15 air pressure.. then I didn't leave it for a long time but it probably didn't have the power to reach 29-30 psi.. at least it went comfortably to the gas station..

Very small in size, moderate power, it needs to not push it too hard. It's okay for bicycles and motorcycles, but for a car, you might push it harder than it can handle

Very good machine, especially considering the cost, it is unbeatable. If it continues to work as it does now over time, it will be perfect. It is small and very convenient in size and for the monthly check of our car tires, it effortlessly inflates them from 1 to 3 b in no time. In the summer, I easily and quickly inflated the sea mattresses. Excellent!

I replaced an older one of the same value. Comparatively, it is much smaller in size, more convenient, and makes less noise. I haven't done any practical tests yet, I will come back when I use it more, but as a tool, it is something that I permanently have in the car for balls, bicycle and car tires, and since I don't have a spare tire, it helped me in a pinch to patch it myself and be able to go to the vulcanizer.

Tremendously convenient, fits everywhere, does its job, economical.

4 tires from 2 bar to 2.5 bar in 5 minutes without much effort.
It attaches perfectly to the valve (screw-on) and effortlessly increases pressure up to 2.5 (which I tested).
In the end, the hose had warmed up slightly, but it didn't worry me.
The power cable is more than enough for a 4-meter car (Peugeot 208).

From a completely deflated car tire of a Peugeot 407, it inflated it within 8 minutes.... 3 people were looking at it and couldn't believe their eyes! I had never seen a similar comment... I mean, if it can handle a completely deflated tire, I hesitated to buy it at first but I bought it for 17 euros and I am absolutely satisfied!

While it provides pressure (bar), it does not have air quantity.
Maybe I made a wrong purchase for inflatable boats, but for a large-sized tire, it took 20 minutes to inflate. Meanwhile, the size is ideal for a car and since it can inflate tires, it is a useful accessory.

Small pump at 15x15 centimeters.
I put it on the front tires and it showed 20psi and actually inflated them up to 30-32 without any problem in 1-2 minutes each.
It is a bit noisy.
It attaches very well to the valve.
The cable is long enough for both front and rear wheels comfortably.
It seems like it will do its job without any issues, considering it's essentially free.
I will come back to see its durability over time.

Very good for its price, the pressure gauge is very close to the gas station and on sea beds and bicycles very fast!!

For its price, it is miraculous and you save both money and space in the car. The question is, how long does it take to inflate a flat car tire? You can find all this in a relevant video on YouTube!

For its price, it's fine. I use it for motorcycle tires, its gauge seems to provide accurate measurements (compared to a separate meter).

For its price, it is very decent. For tires, bicycles, and beach mats, it is very good. The screw valve is a bit inconvenient, but it's not a big issue.

For now, it seems like a very good product.
It attaches much better to the valve than most on the market, essentially screwing it on.
If it holds up over time, it will be a worthwhile purchase

Very good purchase for this money. It has been used for light use (didn't inflate a car tire...) but it seems to work properly and it is quite user-friendly!

Although I didn't expect much due to its size and price, the truth is that I was impressed. It fits very well on the car tire valve. As for the gauge, after inflating the tire from 15 PSI to 32, I went to a gas station to check and saw that it was exactly the same.
Whatever noise it makes, compressors make noise anyway, and that's their job. The air intake rate naturally decreases as the tire becomes more inflated due to resistance.
If the device gets hot enough, then you should close it and wait for it to cool down. However, this applies to all electric pumps.
Furthermore, if your car tire requires, for example, 40 PSI and the device can't handle it, it's a good solution to inflate it to around 30 PSI so that you have some time before it deflates completely to reach a gas station.
Overall, I am satisfied and would recommend it to a friend.
