AstroAI 150 PSI Tire Inflator Portable Air Compressor, Fast Inflation Pump | Cordless Air Pump with Auto Shut-Off,LED Light &Pressure Gauge,L7 Mini for Cars,Motorcycles,Mountain Bike and Balls,Yellow

Sweet little unit. I keep it on bikes now as its 100x easier than a manual pump. This thing has tested well for me. I've done 20 tubed tires empty to full on one charge and battery has lots left. Its powerful and compact.

Way better than i expected, this pump really works! I use it for my bike and my car. And my bike uses those skinny Presta valve, and the pump works equally well on both. Dont be surprised by the noise, means it has a powerful pump. Very accurate psi too.

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 psiPerformance• 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 caseIf 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 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've read the reviews of people stating "Broke after first use!", always thought them to be a bit of an exaggeration.Yeah. No, it can happen.Happened to me with this AstroAI 150 PSI.. . I literally used it one time, worked okay. Tried to use it again about a month later, it made noise, but was pumping nothing up. Tried tightening the hose to the pump, refixing it to the tire stem. Nothing, broken, after just one use.There should be a zero star option.

I highly recommend this product. It is rechargeable, programable, compact, easy to use, pack, or carry in the palm of your hand, as well as being powerful and precise.

My previous review of this device was that it was less than stellar. This was due to the device losing charge over a couple of weeks as it sat in my car. The vendor responded by offering a refund, which I declined since the device was usable in a non-emergency setting. They then offered a replacement, which i accepted.The replacement inflator was received on May 3, 2024 and has been sitting on a work bench since then. The inflator was fully charged when received and has maintained that charge for almost two months. That is an acceptable standby period. Based on this new data and the fact that the inflator does an excellent job and is quite easy to use, i am revising my review to five stars. The vendor's customer service is also deserving of five stars; they exceeded my expectations.

I purchased one of these about 8 months ago. I've used it for lawnmower tires, car tires, Jeep tires, etc. It pumps fast, isn't super loud, and is super easy to use and read. I've purchased other brands and models for friends, and still think this is the best.However, I had noticed a problem when I purchased it, but ignored the issue. I'd charge up the compressor until it was full, but it didn't seem to hold the charge long. A smallish tire would nearly completely drain the battery. I didn't really think about it, as I was super happy to have a cordless compressor that was car and truck-worthy.Recently, I needed to use it again, and, of course it was fully dead. I charged it up, used it, then recharged. After checking 2 weeks later, it was again fully dead. Something is definitely wrong.I thought that maybe I was stuck using this with its cord from now on. But, why not test the warranty? I sent a quick email to AstroAI, and I IMMEDIATELY had a positive response, and have one on its way to me today. The service was exceptional. Thank you so much!I'm a manufacturing engineer for a test equipment company, so I understand escapes of product that doesn't quite work correctly. It's the service that separates exceptional from OK companies. AstroAI is one of the best!Finally, I purchased a portable fridge from them as well. It has been perfect, working for about a year in a wide range of conditions. Buy products from AstroAI with confidence.

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.
