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）

I like this product. It’s very handy and convenient to have around in case you get a flat tire of need to fill something with air. I do wish it came with a carrying case/box to keep it all neat & organized (even just a simple one). But overall i’m happy with it.

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.

I’m impressed with this. I’ve been using it on a tire that has a very slow leak, that I just haven’t had the time to get fixed. The operation is very easy, although the icons for the modes are small and difficult to see if you have 40+ year old eyes. It inflates pretty quickly and isn’t overly loud. I have other tire inflators that will over inflate by .5 psi to account for when you take the inflator off. This doesn’t do that, so just program it for .5 over your target before you start pumping. I like it and will keep it in the Jeep when we hit the road.

After some success with the battery (doesnt last long), the 12 VDC charger did not work.

The portable tire inflator is very light weight. It comes with a rechargeable battery and a battery that plugs into the cars lighter port. Both slide off very easily. The instructions are easy to read and understand. There is a diagram that tells where everything is. Upon taking the inflator out of the box for the first time and just messing with it without looking at the instructions, it was really hard to tell what was the on/off button and what the other buttons were for because they are black on black. Some contrasting color would have helped with that, also if you are trying to use it in the dark you wont be able to read what button is what. However it is pretty self explanatory whatever button you chose. One turns on a flash light which is wonderful, the other is the on/off button, two are for more or less air and the last one is settings. Overall I am very pleased with the item. A carrying case would have been nice to put everything in too.

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.

We live in a remote area, so being able to take care of these car care jobs at home is super helpful. Im old enough to remember free air at the gas stations, so the thought of paying $2 to check my tires every month is annoying. This handy, ergonomic tool has multiple modes to inflate different types of tires or sports balls. Its easy to adjust your target PSI, although in my case the preset 36 PSI is what my tires require. The locking clip on the hose ensures an airtight fit. Pull the trigger and it quickly does the rest, stopping once youve hit your target pressure. My only complaint is that while it includes a USB and a 12v car charger, you have to purchase a plug in charger separately. Theres also no case or bag to keep the inflator and the small parts safely stored together in your vehicle. At this price point it feels to me that those should be part of the package. That said, it works very quickly and makes it easy to maintain your tires.

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

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 falls under the category of automotive tools that its better to have and not need, then to need and not have. Because at some point, youre going to end up running low on air after running over something unexpectedly. And without fail, the nearest gas station is probably going to have something wrong with its air compressor. The last time we left this at home, it took three stops at gas stations before we found one that actually had a working air pump (one of them was completely missing the hose). So this is a real life-saver if you have it in your vehicle. Works quickly, and is effective at helping to you to gauge the exact PSI of your tire as youre inflating it.
