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）

Ive at tried a few portable pumps, but this ones power blew me away. You can easily pump up bike, car, scooter tires in no time. I use it to pump all my vehicles. Also love the multiple presets for bike, scooter, car, ball. Battery lasts super long, have used it to top off my car tires, few bike tires etc, battery hasnt even dipped. Also has 12V power adapter to run off your cars 12V port. Takes prob 3-4 hours to fully charge, but lasts super long. Pros Plenty of power, 20V 37Wh Lithium battery Lightweight Multiple attachments for presta, inflatables, etc Charges w/ USB-C

This works great on my car and my daughters bicycle tires as well, Didnt take that long to come up to pressure on all 4 tires. Works quiet and does a good job. I would recommend to anyone looking for a small portable compressor.

I like the auto off feature, set a pressure and the pump will turn off at that pressure, automatically. It is convenient to use and nice and light. The charger, battery combo is nice, no charger to loose. All you need is a USB cable. The display is easy to read and bright. The LED light is bright and handy for night time use. This is going to be much more coinvent to use than the battery booster combo that I usually use. Very nice little pump setup with all the fittings you need. Just wish it had a closable compartment to house them in, instead of the clip to the side version, they will get lost that way.

So happy, I don’t have to manually pump air for my bike and scooter. My previous pump could not get a consistent seal on presta valves and it sucked. This pump creates a god seal on presta cakes (with adapter) and schrader valves. I pumped my bike to 75 psi and scooter to psi and it stopped automatically at my setting. Can run off of battery off of the car battery. The battery is charged via USB-C. So that makes it easy. Wish I could create more than one custom setting. Also wish there was an Adapter to pump my standup paddle board.

Very convenient platform. I use it on my cars, trucks, and miscellaneous household items.

I like this tire inflator so much that I bought a second one for my SUV. I have a big expensive compressor I keep in my RV, but it has to be connected to the battery of the RV which is great if I have to top off all the tires. If I just want to top of a tire or two, this small tire inflator is perfect. Much quicker as it has a battery, or you can use the cigarette lighter adapter. There are 4 modes and the PSI is saved, so I have one set for the RV, one for my car, one for my motorcycle and one for my bicycles. I quickly filled one RV tire from 66psi to 80psi and the inflator didnt feel very hot. Very happy with it.

I love the convenience of this rechargeable air compressor. I check my tire pressure regularly and add air as necessary. The preset psi works great to shut it off when you reach the right pressure, and I confirmed the accuracy with a separate tire gauge. With my old unit, I had to plug into my car battery, and it took much longer to air up the tires. I had to worry about blown fuses, and the cord was a pain. None of that hassle with this one. It comes with attachments to fill other things as well. There is a needle for balls and a rubber tip for filling inflatable pools/toys. I have this in my garage right now, but it would also be good to keep in the trunk for emergencies. The light is not the brightest, but its enough to help you see what youre doing. As much as I like this tool, I took a star off because there is no way to keep all of the accessories together. You cant even clip them on to the unit itself. The lack of a case to protect the compressor and organize the parts is quite disappointing, and I will have to find something to use for this purpose.

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!

I got in my truck yesterday to pick up a take-out sandwich and go visit a friend. My indicator panel told me I had a low air tire. I realized it was time to test my new tire inflator. I chose to use the car adapter because I felt the battery would probably work, but I suspected more than one tire was low, and this is a full-sized pickup truck, not a little car so there’s a fair amount of weight on those tires. I will test the battery option sometime when I am not so hungry, perhaps on my air mattress. So, the cord reached just far enough…barely. I do wish the cord were just a foot longer for the adapter. That, however is my ONLY complaint. With the truck running, I got plenty of power to add 10 pounds to one tire, 3 to another, and the front tire needed 7. The truck’s digital panel tells me how much it reads in each tire, and when I was finished with all 4 tires, the numbers were perfect. The digital readout on the machine doesn’t work perfectly as I pumped, but it’s good enough. The actual tire pressures were where they were supposed to be when I was done. Doing all 4 tires only took maybe 15 to 20 minutes which I considered to be amazing. It wasn’t a fast fill up, but it was efficient and did the job right there in my driveway. I told my friend about it and now he wants one for his truck. This little compressor worked like a charm and could definitely get me out of trouble out on the highway someday. I’m so happy I have it. What a great tool. The photos in the description are accurate and show the product very well. This is something almost everyone should have in their vehicle, but especially those of us with older trucks that are getting the leaky rim syndrome. It was super easy to use…actually easier than the gas station air pumps for me. This woman calls this an excellent product.

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.
