AstroAI 150 PSI Tire Inflator Portable Air Compressor, Fast Inflation Cordless Air Pump with LED Light &Pressure Gauge, Auto Shut-Off, L7 Mini Tire Inflator for Cars, Motorcycle, Bicycle, Ball, Yellow

Works great. Nice and small. Keep it in the trunk. No more horrible stops at the quick shop in the dark and the pump doesn’t work.

I had this for about a year and used it several times, it works great and is easy to use. Like the preset PSI feature you can set it and make sure all your tires are set to the correct pressure in just a few minutes. The battery lasts a long time, even stored in the truck for months it doesn't go dead. I tend to recharge it right after I've used it or if I think about it just take it out and give it a quick recharge to be sure it's ready in case I need it. The included accessories are great for inflating a variety of other things, and the drawstring sack to keep it all together and handy whenever needed. The size is great, seems very well made and sturdy and not overly noisy. Just an inexpensive tool everyone should keep in their car and not have to pull off the road seaching for a service station with an air hose and then hoping you have quarters to make it work. This keeps me self sufficient and prepared. Definitely a worthwhile purchase.

I tested this AstroAI L7 Mini against a maXpeedingrods cordless inflator and a Ryobi ONE+ handheld inflator (4Ah battery) using a “stress test” scenario. Test setup • Twin-axle utility trailer, 205/75R15 tires • 42°F ambient • Tires were 45 psi cold, filled to 60 psi • Spare tire was 12.5 psi Performance • It successfully inflated one trailer tire from 45 to 60 psi (roughly 5–7 minutes; I didn’t start timing until later). • On the second trailer tire, it ran out of charge at 53 psi (starting from 45 psi). So: it got me about “one full tire and part of another” at this higher pressure range. That’s honestly respectable for a palm-sized mini inflator, but buyers should understand the limitation: this is mainly for top-offs and emergencies, not repeated higher-pressure trailer/truck work. Heat / duty cycle • No overheating or thermal shutdown during the 5–6 minute runs. Warm, not hot. Noise • Not quiet, but not annoyingly loud in an open backyard. (Ryobi was noticeably louder.) Hose / chuck / portability • Flip-lock chuck; hose screws into the inflator body. • Hose is about an inch longer than the maXpeedingrods hose (small difference), and the unit is light enough to rest on the ground or hang from the valve stem while it runs (hands-free). Screen and controls • Outdoor readability wasn’t great overall, but this screen was a bit brighter/easier to read than the maXpeedingrods in my test. • Controls work fine once you learn them, but I wouldn’t call the interface intuitive at first. Keep the manual in whatever pouch/bag you store it in. Charging • USB-C charging only (for my unit). It pulled about 9–10W from my USB power meter, so it recharged faster than the maXpeedingrods. Accessories • Adapters are loose in a small bag (not stored on the unit), so they’re easy to lose. • Adapters screw into the body where the hose attaches (not onto the hose end), which can make inflating odd-shaped items a bit awkward. Weather note • Doesn’t appear weather-sealed, so I wouldn’t want to use it in a heavy downpour. Accuracy note • I didn’t compare against a separate calibrated gauge, but the Ryobi gauge matched what this unit displayed right before battery depletion. Best use case If you want something compact to keep in the car for a slow leak, an emergency top-off, motorcycle tires, or occasional inflatables, this makes sense. If you expect to inflate multiple higher-pressure tires back-to-back, look at a larger unit.

I was surprised of the small size and how well it worked. I found a bag to hold it and the extra components and keep it in my car.

i thought this my be a bit cheap n nasty ...... but it been working great i used it on my car a few times . what i really wanted for; is to go in a bag for motorcycle so if i get a flat out on a ride i be able to fix it and get home .. its nice and small and been working well ..... i say buy it ...

Okay, great idea overall. However, the first unit we got had a broken tire pump nozzle. Got a new one, the new one worked once and now will not hold a charge and will not turn on at all. I tried all the steps aside from change battery which you have to pay for. In all honesty I wish i bought a different unit.

It is quite loud when pumping up tires or balls, pretty light weight, Battery lasts for a while, can pump your car tires pretty well.

For the price it's way better than I expected it it works fine everything is good cordless battery power stays up and you can pop up a lot of tires and it's fast I'm glad I paid it I'm glad I bought it you should get one can't beat the price

Prodotto molto valido. Io lo uso per le bici e fa molto bene il suo lavoro.

Used this to pump wheels on bike, no problems with the presta attachment. Pumped wheel from flat in about 30 seconds. It's loud, as are all air pumps, but not overly so.

Die kleine Pumpe ist wirklich super! Klein, handlich, einfach zu bedienen und mit Power! Tolles Produkt. Kaufempfehlung.

This is my first portable battery operated bike pump so I cannot compare it to others in real usage. I read and watched reviews on every one I could find in the price range and size I wanted. This one stood out for many reasons: size, speed, battery life, 2 year warranty and it can inflate car tires as many out there say in small character'' not for use on car tires'', this one is! The moment of truth was when I used it, it works great, pumped up my bike tires from 30 psi to 50 psi in no time. The noise level is very acceptable for what it is, it's a air compressor so it will make noise! As for the actual battery life, it stayed full bars but I only pumped up two tires with it. Comes in a nice little velvet pouch for the pump and accessories. Time will tell if it will last a long time but from what I can feel and see, it should, the build quality is really good and solid! Very happy with this little pump which I will ad to my e-bikes' carry bag. If you ride a bike often, you need a pump and a flat repair kit for sure and in my book, this little unit is a winner!

Una herramienta muy útil para llantas de automóvil y bicicletas, sorprendente lo fácil y efectiva que es. Si eres de los que te preocupa la seguridad y no confías en las estaciones de servicio o gasolineras, este es una buena inversión. Ademas los materiales son modernos y de buena calidad.
