AstroAI Tire Inflator Air Compressor Cordless Car Tire Pump with 20V Rechargeable Li-ion Battery 150 PSI Portable Handheld Air Pump with 12 V Car Power Adapter for Cars Motorcycles LS40791（C1）

This is awesome for the average homeowner who needs to inflate bicycle tires and occasionally inflate a car tire. Dont know about you, but every time I go to the gas station to fill my tire (after the tpms light comes on), the air compressor either costs money, is broken, or there is a long line. Hah! No more of that. Just attach this unit to your tire and the led shows you the current tire pressure. Enter in the pressure you want and click the trigger and it inflates the tire to that pressure and automatically shuts off. I checked pressure with a second tire gauge afterwards and it was spot on. So easy that I am looking for other tires to fill! In my opinion, this would make a great housewarming gift for someone to add to their tool collection.

Got this today. I immediately tried it and it now replaces the inflater Ive had for a few years. There are quite a few of these inflaters out there. I like this one for two reasons - it can be used with its internal battery or plugged into your cigarette lighter. The other reason is mentioned in the headline - the connecter is the push and clamp down type of connecter that you see on bike pumps. This is way better than the screw on type of connecter which normally gives me fits, trying to screw it on to the valve stem. My only concern is how long this device will hold a charge. It could spend a year sitting in my trunk until its needed. If the battery does drain down in that time, Im glad the adapter with a decent amount of wire is included. I gave the screw on type of inflater to my son - its his problem now!

This offers a piece of mind. Charger included for on the road power at any time. Additional pieces included for the type of tire filling. Recently had a slow leaking tire and this offers a peace of mind to be able to help myself in such a circumstance

This little thing is pretty amazing especially at its price point. I love that you can set a tire a pressure, my car calls for 41psi so not having to guess is incredible. Its perfect for road trips, its super portable. The light is a smart addition in case you need to adjust your tire pressure in the dark. The fact that it has two power sources is also really cool and very handy. It can be a little loud while its working but Ill take that over having to find a gas station with an air hose any day. If you got a road trip ahead or just like to be prepared this is a must have. Its well made and well worth the money in my opinion. 5/5.

Works but a bit slow handy and portable

Its too bulky to stow on my motorcycle, but my full size SUV accommodates it nicely. The quick-connect attaches securely, and is nice and snug - no signs of air leakage once locked. It also releases cleanly with very little air escaping. The LED lights surrounding the hose provide good illumination. The various modes are basically pressure presets; expect to have to adjust them for your specific needs. It does remember the last pressure setting for each mode, which is nice! The auto-shutoff is a very welcome (albeit common) feature for inflators nowadays. I compared the pressure readings to another digital tire pressure gauge that I have; this pump tended to read a couple of tenths above the other pressure gauge. I would consider that within an acceptable margin of error. My SUVs all-terrain tires were all at 30 psi. I first used the pump, on car voltage (with engine running, so about 14.5V), and raised a tire from 30 to 35psi in 4 minutes. I then switched to the included battery (18.5V), and raised the next tire from 30 to 35psi in half the time - 2 minutes. I continued on that second tire up to 40 psi, then raised the third tire from 30 to 40psi in 4:30; fourth tire from 30 to 40psi in 5 minutes. There was only enough juice left in the battery to raise the first tire from 35 to 38psi before the battery ran out. So, the pump does run better on the rechargeable battery than on car voltage; makes sense, since the rechargeable batterys voltage is higher. The battery capacity is very decent; I estimate that you could easily fully inflate one flat car tire with maybe a little bit of juice to spare. All in all, I am pleased with this pumps performance. The battery adds great versatility if youre away from an external power source. I do recommend this product for your consideration.

Like many newer cars, ours lacks a spare tire and, instead, includes only a 12v compressor. Sadly, the tires are always losing air no matter how many times we take it in for repair So, the included compressor gets used — and cursed at for its flaws. This battery operated compressor is a huge improvement. Most importantly, I don’t have to fool around with wires and cigarette lighter sockets (unless I use the included 12v adapter instead of the battery). Next, it’s automatic. I can set it for a precise pressure, start it and go sit in the car until it stops. There are several presets, plus it uses the most recent setting if different. All four tires come out exactly the same without any fooling around. My tpms reads two psi lower than the compressor setting and I don’t know yet which is correct, but I’ll figure it out. It charges and pumps slower than I hoped (but not slower than any other 12v compressor I have used), but the time saved by not having to adjust the pressure or stand outside monitoring it more than compensates. The screen is easy to read and the settings are simple and obvious. There is always room for improvement and this compressor is no different. I would like to see a compact case or sack to protect it. I also would like it if the accessory connectors could be secured by clipping onto or screwing into the casing. (It looks like something like that was contemplated but not actually accomplished. There is a place to clip the hose. There are a few other fittings but they aren’t really secure.) The 20v battery looks remarkably like a Dewalt, but sadly it is not identical, so I cannot substitute batteries/chargers I already have. No doubt there are legal reasons for this. The battery, however, is lithium and will receive such light use that it should outlast the car. If the battery eventually fails, there is always the 12v adapter.

This inflator works great & is compact. Comes with plenty of attachments.

This handheld air compressor is seriously the coolest. My husband has a large air compressor in the garage but it feels intimidating to use, and sometimes I cant get whatever it is I need to fill to the garage. This handy compressor is so user friendly and easy. It comes with different attachments so you have what you need to fill a tire, ball, or whatever. The rechargeable battery is so convenient and if it happens to be dead when you need to inflate a car tire, you can plug the attached power cord into the lighter socket and youre good to go. Also, you could charge the battery with the provided USB-C cord if you are set up that way in your car, but it will take a little bit (particularly if youre in a hurry). The settings are simple to understand, as well. Theres a screen that shows four pre-set options for bicycle, motorcycle, car, ball and you can also pick from PSI, Bar, kPa, kg/cm2. If you dont want to use a pre-set option, you can either set your own pressure limit, or just press the button and fill until you want to stop. When using a pre-set option, or setting your own pressure, it will automatically stop when it fills to the pressure its set at. If its dark outside, there is a light button to illuminate the area so you can easily connect to the valve. Its pretty lightweight, considering it has a battery attached to it, and easy to handle. It feels durable and well made; I appreciate how easy it is to use every time I need it.

This portable tire inflator is very powerful. It comes with two ways to use it, by plugging into your vehicle or charge the battery. This way you never have to worry about not being able to use it. You put in the amount of air you want and it wont stop until it reaches that amount. So much easier than adding air, then checking the pressure over and over. This is a must have for anyone. It also has attachments to fit different things that need air.
