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 cordless pump has been a game changer since switching over from my manual pump. I’ve used this to pump my bike tires and scooter tires, and the pressure gauge seems to be pretty accurate. The best part of that I can set a PSI target and when my tire hits it, the pump automatically stops.

Got this tire inflator for my bikes and cars. There are quite a few other battery and wired air inflators on the market, but got this one. It arrived in quite a large box, and was well packed. The pump itself is fairly bulky and includes one battery that can be charged with a USB C charger, and also a battery shaped receptacle that is basically a corded DC plug, to allow plugged in operation. The battery charges fairly quickly, but I think it depends on the type of charger block you have. Mine is a high wattage fast charger and took about 1 hour for the first charge. The operation is very easy, and just requires that you plug in the battery like a power tool, set the air pressure, connect the hose and pull the trigger. It automatically shuts off when the desired pressure is reached. It pumps at a decent pace for the type of pump that it is. It didnt get too hot either when I used it to top off the car tires. I do wish it included 2 batteries. I feel this is a very good light duty air pump.

Really like this tire inflator. 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.

Works but a bit slow handy and portable

This is pretty convenient since my car’s 12 volt plug doesn’t work. I can just pop the battery on this and use it. The battery life is good and only dropped one bar after airing four car tires. It auto fills to a certain psi which is also pretty convenient. My husband said it’s pretty accurate, just off a little bit. It’s pretty bulky but it’s designed to look like a power tool so it’s whatever. There is an area on the side that has what might be to hold the tips or something, I’m not sure. But they’re little plastic rectangular shapes and really sharp. I actually cut my finger the first time I held this. We just sanded the corners, but what’s the deal there? Otherwise, I like this. One star off for the assault.

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.

This little dynamo is a life saver when you find yourself with a flat tire. It has come in handy several times for me so far. I have a slow leak in one of my tires and I have come outside to a tire that was down to 15 PSI. Too low to try to attempt to drive on it, even slowly and no other way to put air in. I can air the tire up from a low of 5 PSI to 36PSI one time on a single charge. A complete lifesaver when in need. Even though the tool looks cheaply made. It has some weight to it and is built from quality material. It is quieter than I had thought it would have been. It’s not a fast process when airing up a tire but it does get the job done. I did find It to be approximately 2 PSI off from what it says it’s at and what my tire pressure gauge says it is.

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.

Just got it a couple days ago. Works great! Perfect for our cars & SUVs.. we can even inflate our bicycles! It’s a bit loud but I guess that’s because of the compressor inside. Overall great product and great price!

The cordless design of this tire inflator is a huge advantage.The built-in rechargeable battery provides ample power to inflate car tires quickly and effortlessly, making it incredibly convenient, especially in emergency situations or when on the road. The compressor delivers a consistent and powerful airflow, The LED flashlight feature is a thoughtful addition, providing extra visibility during nighttime or low-light situations. Easy to use right out of the box.
