My son plays basketball a lot, and considers a bball inflator a must-have tool in his kit. When his other auto inflator disappeared, I replaced it with this one. It works fully as intended -- set the pressure, connect the pump to the ball, and press play. It automatically stops once the desired pressure has been reached. It's about as tall as a can of soda, and just slightly thinner. It comes with a few extra attachments, a hose that sits inside the housing for safe keeping, an LED light for use in low light environments, and charges by USBC, making it super easy to charge. My son's happy with it, and so am I. For future improvement, I'd love to see the needle attachment (and others maybe?) have their own protected spot in the housing like the hose.

For its small size and reasonable weight, this inflator is surprisingly powerful. A must have with you for bicycling or out playing ball. Has a selection of preset pressure limits in a wide range. Naturally quite noisy. Apparently not suggested for car tires.
Perfect design and well made, with a USB-C charging input and a USB-A cable included. Good value for money, exceeding expectations. Comes with a cute mesh bag.
It may get hot if used long time.

Nice compact, easy to use, portable compressor. Being only about 5.5 inches tall and a couple of inches around (slightly taller and more narrow than a standard 12oz can - see pics), this portable inflator will not take up much room in my motorcycle bag. If you get a flat tire on your car, you usually have a spare so it is easy to continue your journey, at least until you can get to a regular tire shop. In the case of motorcycles and bicycles, spare tires are not an option, so you either have to perform on the side of the road tire repairs or call roadside assistance and have your bike picked up and taken to the nearest motorcycle/bike shop. And, you might not have the roadside assistance option if you are out in the boondocks. So, if you are lucky enough to be able to patch or plug your bikes tire, you still have to inflate it. Having a 150 psi max should be enough to handle most any bike, motorcycle, or cars, in an emergency situation. So, at least for me, I won't be taking any out of town MC trips without an emergency tire kit and this inflator.
And if you want to blow up your balls (toys too) this compressor has the attachments for that job as well.
My only grip, and yes, it may be a minor one, is the itty bitty manual doesn't mention much about the battery. So, I have no idea how long the battery will last, what technology is used (Lithium Ion, NiMH, NiCad, etc), and if the unit needs to be charged upon receipt (it wasn't at 100% out of the box) or if it needs to be charged only when the battery is completely depleted. The whole battery thing would possibly not be an issue if the unit worked while it was plugged into an external power source, using the included USB cable. Unfortunately, this mini compressor does not work while it is plugged into the charging cable.

I've used this to inflate a few bikes, and other items and found this to be very helpful. I wish it lasted a bit longer however. It inflated 6 standard size bike tires before the battery died from being completely flat. I don't know if it would last more than one or two car tires if I was using it for that.

This lightweight mini air pump (0.79 lbs, 5.42.22.2 inches) is perfect for on-the-go use, whether for travel, biking, or camping. With a 150 PSI max and 3 interchangeable heads, it efficiently inflates bicycles, motorcycles, sports balls, and more. The auto-stop feature ensures precise inflation, while the LED light and multi-mode functionality make it ideal for nighttime use. The dual digital displays allow easy monitoring of preset and measured pressure, and quick charging is available via Type-C input. A great tool for all your inflation needs!
