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 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.

I have a couple normal compressors, but theyre both a hassle to get out when I just need to air up the tires a few PSI. I got the AstroAI Air Compressor with the intention of it solving for that use case. I thought the form factor would be a REALLY nice feature, considering that the compressor can stand upright on its own. The reality, though, is that the usefulness is limited by the really short inflator hose. Even with 245/40-19s its easy for the valve step to be up and out of reach. Ive had to put the AstroAI on an overturned bucket on more than one occasion. While its awesome to not have a 12V cord strung back to an Aux power jack in your car, its good to have reasonable expectations of what you can do with that battery. I ran it down by 3/4 by filling 4 tires from ~35 PSI to 42 PSI. You set inflation pressure on the device, and it shuts off when it reaches the setting. Thats a nice feature because you dont have to keep checking the pressure. Its also good from the standpoint that the inflator is tragically slow. Filling larger tires, or from lower pressures (or both) could be a real problem for this unit. Its worth noting that you probably dont want to run this thing for long periods of time, either, as the compressor just isnt built for that. Speaking of batteries, this battery pack appears to be completely proprietary. While its possible that this will last for years and years, you will still have to (eventually) deal with the battery dying and not holding a charge. Fortunately, it looks like its made of normal 14500 cells, so you can rebuild the thing yourself (if you have 30 minutes, and a good attitude). For seasonal tire top-offs, bike tires, and pool toys, this is a decent occasional use inflator. Conditionally Recommended

This machine is fabulous and helped me fix my sons friend bike tires I am sorry but I didnt have have my phone at the time to take a picture (lol) but it worked wonderful and super fast too. Great investment

Perfect for keeping under the car seat. It isnt too large. Had a battery pack or cigarette lighter adaptor. Every few months I need to top off my air pressure to keep my tps system from giving me an error. I usually keep apt 36psi in my tires and when I started inflating they only had 33psi it only took about 10seconds on each tire to get to 36psi. The built in air gauge to set how much was great.

Work great. Quick and accurate. I rather use this than to go to any gas station. Im purchasing another to place in our other vehicle.

This air compressor is great. Just tell it what you want you tire pressure to be and it pumps it to that and shuts off. Comes with a rechargeable battery and also a hook up to run it straight from your vehicle. The only knock I have on this item and the reason it is not getting a 5 star review is I wish it came with a carry bag or case and not just the box it came it.

Works but a bit slow handy and portable

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.

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.

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.
