Super useful and reliable!
This portable air compressor has saved me so many times already. It’s very easy to use, works fast, and is perfect for emergencies or everyday use. I love how compact it is, so I can keep it in my car without taking up much space.The digital display is clear, and it lets you set the pressure easily. It automatically stops when it reaches the desired level, which makes it super convenient.Overall, it’s a must-have item for anyone with a car. It has definitely given me peace of mind — highly recommend!

Great value. Works well.
Pretty amazing little device. Topped off my tire pressure on my Ford Ranger pickup. A little longer valve would be nice but it does the job.

works great for a variety of uses, no complaints. recommended
I’ve used it to top-off car tires, inflate multiple bicycle tires and a huge yoga ball.It shuts off after a minute automatically so for a large job you just need to re-start it until whatever you’re inflating is full. It took 9 cycles to fill the yoga ball, and a full battery charge. I haven’t done it but I imagine that you’d use a full charge to inflate a car tire, possibly a few charges. It is not meant for that, although it could do it if you were patient. Top off the car tire with a few lbs, inflate bike tires, sports ball. Perfect for that.Includes a variety of attachments and 2 hoses that screw onto the body via brass threads. One hose has the tire inflator and a brass adaptor is included for bicycle presta valves. The other hose screws onto any of the 3 specialty nozzles for inflating basket balls, soccer balls, yoga balls etc.It has 4 presets that you can adjust, scroll through them with the buttons, each has an icon for it’s use (a car, a bike, a ball, etc). You adjust the pressure for each icon and it’s set. 35 for your car, 60 for your bike tire, 8 for your yoga ball etc.USB C charge port, it seems to hold a charge for a long time. I keep it in the car for emergencies but bring it out for bikes and sports balls as needed. It’s been 100% reliable so far.

Effective tire inflator for home.
Shipped quickly. I had a problematic tire on my SUV so I tried it there. Needed to add 5 psi and after about a minute and a half or so it got the job done nicely.I tested the psi readout to my manual pressure gauge and it was very close.The unit is pretty simple to use, instructions are pretty clear. I like the compact design and clear read out. When the device is in use, and the pressure equals your pre set, it stops as described.I have one minor gripe. After charging this I placed the unit in my garage on the workbench. Overnight temps there were in the mid 30s F. The unit showed the battery was low (only one bar lit) the next afternoon. Still did the job but I have a concern overall regarding holding a charge. I will continue to monitor.

A good purchase IMO
This is probably one of the better items I’ve purchased for myself in a while. It does exactly what it says it will do, and the price was way better than what you can find at Academy and Dick’s Sporting Goods. This was easy enough for my kid to use to inflate all of his soccer balls and basketballs. There was still plenty of charge left, and it was small enough to pack up into his gym bag and take with us (and help other players on the pitch, if needed).

This thing works great!
I was somewhat leery of buying this. But after reading all the rave reviews I decided tochance it & I was not disappointed! My car in the cold weather was always telling me that Ihad a low tire! Most of the air machines at gas stations are worthless & just take your money! So the first time I used this I didn’t know what to expect. Turns out it was soooo easy! And didn’t take long at all! I recommend this to anyone who finds themselves needing to air up a tire! It’s well worth the price!

Great Air Pump
This is the second one I bought, I gave the first one to my mother-in-law. It’s so easy to use. I love this little gadget. It pumps up balls, bike tires, and car tires. It is so handy and small to carry. I got this one to carry on my electric bike.

Works reasonably well, though with an Achilles’ Heel.
I’ve had to use this on tires that were very low, both on cars and on bicycles. It works exactly as you’d expect and absolutely has no trouble handling the much higher pressures of bike tires as well as the much larger volumes of typical car tires. I kind of wish it came with some sort of pouch or something because the box it comes in is the only means to store it with all of its attachments,; Because of how tightly it’s all packed in the box, it’s a bit of a pain getting it all arranged neatly in the box each time, but that’s a minor quibble.If Amazon reviews allowed fractional star earnings, I’d probably rate this more accurately a 3.75 or 3.875. It still has two little flaws. One is the accuracy of its pressure gauge. It always seems to fall just a little short. For example, on my car, recommended cold pressure is 36 psi in front and 39 in the back. I tried pumping to those levels, and everything looked fine. But immediately afterwards, the TPMS sensors would tell me I’m at 35 and 37. Likewise, I like to keep my bike tires at around 42 psi for my commuter bike and around 70 psi for a road bike. After using this little guy, and double checking with a separate gauge, I was getting closer to 40 psi and 67.5 psi respectively. I’m inclined to believe it’s a calibration/QC problem and there might be examples that overinflate, too. So while I got one that was overestimating the actual pressure, you might get one that has the opposite issue. Still, close enough that I’m not docking it a full point for this, but a faction of a point.The biggest weakness of this device is really a double-edged sword — its compactness. The fact that it is compact means that it fits very nicely in the under-trunk storage or even a glovebox in some cars. Problem is that when the device is small, so too is the battery. There’s just no escaping this. I had a moment with all 4 tires on my car being on the low side in terms of tire pressure. They were all underinflated by about 6-7 psi below spec and so I just used this pump to get them all up to that target pressure. Even with a full charge, I could not get all 4 tires all the way up to target pressures. I could get the 4th tire about halfway there, but that was where the battery died. That’s just a reality you will probably have to live with. Given that it is such a small device, this is basically inevitable, so there’s no sense complaining about it, but it is a reality you should be aware of.

Muy bueno y dura bastante la bateria

Excellent little tool.It can run pretty long, has a simple interface, all the tools you need, it’s light and small, and powerful enough for the casual user.The pressure reading is nice & accurate, too.If there’s one small negative; I can’t find a way to reduce the pressure. So that’s a manual operation by “feel”.Another future improvement would be to set front/rear pressures separately (i.e. more saveable presets), but this is by no means a problem, it’s easy to change the pressure.

Je l’ai utilisé directement marche parfaitement avoir dans le temps mais pour le prix cest pépite ( utilise pour ma trottinette et ma voiture)

Use this all the time when I get low pressure in the tires. Works really good. Just make sure you recharge it and put it back into your car when you used it. Have saved me when I run over nails and screws and you get a tire that slowly let out air.
