stay away it is not a good product besides the fact that it arrived to me slightly broken and melted, with the first use it overheated causing the plastics to melt and other worse things ..

I blew up two bicycle tires. On the third one, the gears started whistling. I opened it up! The front axle has no security, it moves and the gears spin in the air (deafening noise). I create security (patent), and I go to inflate a ball. Squeaks, screams, massacre!!! I was happy for nothing that something so cheap would solve my problems. If you feel lucky, go for it. One in a million might turn out good...

Just got it and tried it out. It seems good for its price. I don't know yet how durable it is. However, the barometer is useless. It shows 4 bars when the tire has 2.3. So you need a reliable pressure gauge, which increases the cost and it's not particularly user-friendly.

Although it arrived with a broken supply hose, I kept it and repaired it. Now it is only suitable for balls as the adhesive does not inspire much confidence.

On 12/4/2019, I ordered the "220V Power and 12V Battery Compressor with Pressure Gauge (pump)". Since then, I had opened it once to test if it works on 220V and 12V battery. It indeed worked. On 2/10/2020, I used it, essentially for the first time, to inflate a bicycle tire using the 12V car battery. When I tried to stop the inflation at 3 minutes, the switch got stuck, resulting in it no longer functioning on either 12V or 220V power. I was informed by the online store where I purchased it that it does not have a warranty on its functionality.

It does the job, it is not the most high-quality and it needs testing before you get it. The first one I got didn't even release air, but the second one is fine

It didn't last even 3 uses. The barometer was not accurate from the beginning. So I put it to measure 2 bars in a pressure container. After a minute, it started smoking and something broke inside. The most useless thing that has ever existed. Money wasted.

Finally, it delivered gears..
I went to inflate a bicycle, and on the second tire, everything broke inside it..

[Initial Review]
It made me look good (literally, I didn't turn red from inflating) all summer inflating boats and mattresses for the kids from the car lighter.

As soon as September came, I started inflating bicycle tires from the 220V socket.

And at parties? It inflated the balloons perfectly.

Not to mention the balls that deflate at home, but I have the solution.

Without much use (it barely inflated twenty balls and not all at once) and after a year it no longer works. Stay away

I acquired it a few days ago. In its first function (inflating a ball), it was OK. In its second function (inflating car tires), it broke!! It lost the ability to produce pressurized air. It sounds like it's struggling and, of course, it doesn't inflate at all! It also has a useless car lighter socket input. If you connect another car tire pump there, it simply doesn't work!!! It is truly the best item if you want to throw away your money!!

I did not expect such quality from the OEM. For now, it works fine, I will see in a year. Be careful, it cannot withstand more than 10-15 minutes of continuous use - the on-off button will break and the plastic will dissolve. I experienced this myself, but I won't deduct stars, it still functions and it even had instructions stating that it cannot operate for more than 15 minutes continuously. For the price of 21-30 euros, it is a very good product, just be a little cautious.
