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 will be our second purchase of this item.... the delivery was on time, the unit was properly wrapped for shipment and the quality of the unit is excellent.

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.

This tire inflator works great - and for a multitude of things! We have in our camper, should we need it traveling - but it’s also super helpful for pools, balls, etc. So happy we came across this!

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.

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 portable inflator is very cool. Its shaped like a cordless drill, complete with a trigger to turn airflow on/off. The lithium battery is contained in a removable battery pack at the bottom of the unit, but if you prefer to use DC power from your car you simply switch out the pack for the one with the DC power plug. I havent seen many portable inflators that operate on both rechargeable batteries and DC car power. Its usually one option or the other. So its nice to have both options in one unit in case the lithium battery dies, or if its inconvenient to plug into the car and start the engine just to inflate a sports ball, for example. There are default settings for inflating bike tires, car tires, motorcycle tires or sports balls. Default settings are easily changed by pressing the plus or minus keys. When the desired pressure is displayed, connect the hose to the nozzle and press the trigger. As soon as the desired pressure is achieved, airflow shuts off automatically. If you prefer to inflate tires or sports balls by feel instead of by specifying a set pressure, just press the trigger to start inflating and then press again to switch off airflow. This is great if you want to inflate a volleyball, for example, to slightly less pressure than the label on the ball recommends. One product photo shows the guy holding the unit to the tire and pressing the trigger, suggesting that you have to hold the trigger to inflate. This isnt the case at all. You press the trigger once to start airflow, and then press again to stop (unless youre using the auto-stop feature). The unit is somewhat quieter than comparable inflators. More importantly, its fast. Using the lithium battery, it took me a little more than half a minute to go from 13 psi to 25 psi when inflating my ebike tires. Price is reasonable for what you are getting. I love this inflator and definitely recommend it.

This portable inflator works fine and is convenient to hold and use to blow up tires, soccer balls or anything that needs air. It comes with all the tip adapters you will need and the fact that its cordless with a 20V battery makes it very convenient if youre not near an A/C outlet. It also has a 12V cigarette lighter adapter so you can run it off your cars accessory port. It has a USB-C connector to charge the battery and comes with a USB-C to USB-A charging cord but it doesnt come with the wall charger which you will have to purchase separately or borrow one from your cell phone. The lack of a charger and the fact that it doesnt come with a carrying case to store everything in, prevent me from giving it a 5-star rating.

This thing is fantastic! Its way more powerful than I expected it to be, but also super lightweight. Weve used it for bike tires and a leaky truck tire and its been awesome not having to pay at the gas station or pull out our bigger air pump every time we need to air something up.

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.

I do a fair amount of driving. It always concerns me that I am going to have to replace a tire on the side of the road due to an errant nail, and because I cant safely drive to the nearest station. So when I ran across the AstroAI cordless Tire Inflator, I knew I had to have it. This nifty device has a Li-ion battery that holds a charge for considerable time, to be ready when and if you experience an unfortunate event on the road! Admittedly, I used this only briefly so far to test it out. I have to wait for a REAL flat tire in order to put it to a REAL test! However, for the purpose of testing and preparedness, I did go ahead and deflate my car tire a few PSI, then used this device to refill it. The battery held great! Here is the best part. Lets say you forget to charge the battery. That is OK - if you have this product, you can simply connect it to the car lighter port and it works flawlessly. I only have one small thing that would improve this product to perfection. It should come with a bag. There is a tire inflator, a rechargeable battery, and a few connectors. When I put this in my trunk, it would be nice for it to stay all in one bag. Inevitably I will be searching for that battery (or connector) when I need it. I could also supply my own bag... yes. There is that. This is a great device for giving you peace of mind on the road. I highly recommend it. *** OH SO! *** Peace of mind for the road Multiple ways to inflate a flat tire *** SO-SO *** Should have a bag for the trunk
