AstroAI L7 Tire Inflator Portable Air Compressor,150 PSI Cordless Mini Air Bike Auto Shut-Off Pump with Digital Display Pressure Gauge, Fast Inflation & LED Light for Car Tires,Motorcycles,Bikes,Balls

Great product! The AstroAI L7 Tire Inflator is compact, easy to store, and takes up very little space in my vehicle. Despite its small size, it has plenty of power and inflates tires quickly and efficiently. It's simple to use, reliable, and gives me peace of mind for emergencies and routine tire maintenance. Definitely a worthwhile purchase.

My husband and I LOVE this portable tire inflator. A coworker recommended this type of device so I got it. It works great for our bikes and even the jeep tire. I love that it's rechargeable and easy to use. You can set a psi and it'll automatically pump to that amount. Best father's day gift!

Great for keeping handy for bikes and even some use on the car tires. Pumped all 4 golfcart tires up from 10 to 22 psi. I am pleased with this purchase and keep it in our Jeep at all times. Works great and is compact. Easy to use. Do read the directions about maximum continuous run time and required cooling off period. Recommend & I would buy again & expecially as a gift.

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.

OK, I wanted to try a CAR tire inflator that took up little space and this one works great. It took about 30 minutes to get full charge. Then I let it set for an hour and it still was fully charged. In my garage I let air out of my Jeep tire on the vehicle. The tire pumped up to set pressure of 38psi. Recheck psi with another gauge, was correct. It took about 15 minutes with one bar of charge left. Cons; does NOT come with a 110-120v adapter; only one tire per charge; hose will get hot and is short but you can let it hang; time will tell on battery. pros; easy use, not very loud, good display reading for seniors, lots of different connections for bikes and sports balls. For me, not enough cons for lower than 5 stars.

Dead simple to use right out of the box and had no issues. The fact it came fully charged shows the attention to detail they have with their product. pumping up my tires before a ride every time is a pain in the neck so being able to just set it and forget it is the best. And the Presta attachment worked very well and I was surprised by how little air was lost when detaching the pump. Overall I'm extremely happy with it and can't wait to use it on all my inflatables.

So, the AstroAI arrived today. It was left in the mailbox because it was raining like crazy at the time. I had to go back & watch the videos again to learn how to use it. I'm like what does this thing at the top on the right hand side do. It allows you to screw in the hose & use it as a handle for carry; interesting considering it's small size. It fits into the palm of your hand. To my surprise, it comes with 2 hose attachments. One that screws onto your tires & the other one that snaps onto your tires. It also comes with the other smaller attachments. It comes charged. I tried it & it works great. Definitely worth the money because you don't want to be left on the side of the road or stranded at work coming out to find your tire has a slow leak, especially after working all day!

Cheap, efficient, and reliable. Small enough you can bring with you and keep in your car, pretty flimsy build but the hardware doesn’t get damaged. Overall, for the price a really good product. However if you’re in a rush, please look for other options. My car tires need 35psi at operating pressure, the amount of time it takes to go from flat to full is absolutely laughable. One tire took well over 15 minutes and drained the battery. Which don’t get me wrong, this thing is best used in case of emergency, even comes with little lights that you can turn on to let others know it’s there. But if you’re looking for a solid item for emergency occasions, this is a really solid pick, it’s highest setting goes all the way up to 150psi so it will work with some of the larger end tires too. Stranded out in the middle of nowhere on a flat, this would save you.

جدا رائع واتمنى ان البطارية لا تتلف مع الوقت لقلة الاستخدام

Helt suverän. Pumpat upp elscooter däck, skottkärran och ett bildäck utan att behöva ladda batteriet än👍

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

very impressive

W sumie kupiłem już 3. Bardzo dobry produkt. Dobra bateria, dużo adapterów, trochę głośna ale jak na swoje gabaryty bardzo wydajna.
