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）

So my old air compressor I used to carry around was not digital, was much bigger, and kind of annoying to lug around. This, by comparison, is smaller, digital, and fairly easy to use. The fact that it comes with both a battery and an auxiliary socket power adapter is a nice bonus incase the portable battery happens to be dead. Running on battery power, I can just easily walk to each wheel without being tethered by a lengthy power cord to the inside of a car that has to be on. I used it to check my tire pressure and as it turns out, the dealer (who recently did a TPMS sensor recall on my car) had overinflated my tires. Not having to have a separate tire pressure gauge and compressor is also a nice plus (the pressure sensor in my old compressor was very inaccurate) and the quick connect/release is a blessing. Overall, I really like the design and function of this and give it high marks. It has earned a spot as the permanent replacement for my old compressor.

This tire/bike/ball inflator is a handle tool to have in the car and garage for quick fill ups. No longer to do you need the large compressors to do these quick fill ups. This fills up tires so quickly, it has various attachments for everyday needs with pre-set filling modes to make it even easier. Charging was quick and the battery if you choose to use the battery lasts about 15-20 mins not too long, but you have the other choice of using direct 12V power from the car which is a great option. The large LED makes it great to see where the pressure is even in nighttime. Nice product and peace of mind.

I tested two entirely different types of this product at the same time. The other, a slightly less expensive u it, was more user friendly and simpler to understand and use. The one you are considering here seems better made and designed, but it is harder to understand. Another drawback is that the first time I used it, it did not automatically turn off when it reached the preset PSI. I’m not sure why that is, and I’m still messing around with it to figure this out. The included instructions offer no insights to this. Otherwise, it is powerful and very well made.

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.

I wanted a small compressor for two tasks, topping off car tires and filing bicycle tires. This one tucks away easily in the car so its always available. Power comes from either the lithium battery pack or a 12v accessory plug adapter. The battery charges via USB-C, preventing the need for yet another charging brick. My existing chargers work well with it. Controls are not obvious but can be figured out. Tested it by topping off the tires on my less used car. One tire was down about 3psi. It took about 12-20 seconds to get it up to pressure. Unit automatically shut off when target pressure was reached. Checked the pressure with a calibrated gauge and it was within 1/2psi. It is noisy but I havent found a compressor yet that wasnt. It comes with adapters for inflating sports balls, floatation devices, and a Presta to Schrader adapter for some bike tires.

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.

So far we have found this to be a handy portable air compressor. This is both battery powered or can be powered by your cars 12V outlets. This comes with a few adapters to fill balls, bike tires or blow op items like a beach ball, air mattress and such. The battery charges from a USB C type connector. When charging there is a Red LED & when done it changes to Green. The battery does not have a level indicator. When you connect it to the compressor the display will then show in bars how full the battery is. The instruction manual is in several languages. This is fairly easy to use & you can change the measurement from PSI to a few other options. There are also LED lights to help if using in the dark. There are 4 different modes where this will have a pre-set PSI that you can override. When you connect this to your tire & clamp in place for example the display will show the current pressure in the tire. Once you have the desired pressure set simply press the trigger & this will start the compressor. It will run until it hits the desired pressure or maybe 1 PSI more & will shut off. When I ran this on my SUV tire using the battery from 5 PSI to 36, it was slow as expected, ran till the indicator showed 37 & shut off. When I compared to my dial gauge, they were within 1 PSI of each other. The compressor only got warm but the hose was very hot to the touch. Releasing was as easy & placing on & I did not release hardly any air from the tire. This would have been great to have in the car a few weeks ago where we picked up a nail & slowly leaked so we could have topped of the tire a few times until we could get off the highway. This is the main reason we got this now so most of our cars have some sort of compressor in the car. This is not heavy & is more coinvent to use around the house for balls, bike tires Vs dragging out our larger compressor for those little jobs. This will also be great to take along camping for the air mattress or blowing up snow tubes. So far so good this is a convenient little portable compressor that is battery or 12V car operated.

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.

This is great, very nice quality! Was thoroughly impressed and exceeded expectations. Im not even sure what all it can do however it was easy peasy for airing up my tires. Youre able to set the amount or pounds of air to your liking and then simply hook up to tire gage and it fills it to thay pressure and stops when it reaches it. It cane fully charged and even after filling up a flat and going around both our cars and adding even air to them it still is charged. Super convenient and even used to air up a pool and bike tires easily. Comes with different tips to be able to connect to different air nozzles too. Not heavy but powerful. It is so handy! Very happy with it and have had no issues after multiple uses. Shipped fast too!

I got this tire inflator to replace a previous one I had that never worked, which itself had replaced one that died after a couple of uses. This one looks more promising. It is working well so far, and it has a much more capable battery. Once charged, it was able to put 3-5 lbs of air in each of my four tires to bring them up to where they should be. It seemed to have plenty of charge left, but I had no way of testing to be sure. But the fact that it was able to do this was enough for me. If it should run out of juice, you can connect it directly to the 12v cigarette lighter in your car to power it. It includes a USB cord for recharging. You can plug it into any USB charger, but be aware that if you use a charger designed for a cell phone, it will take a long time to charge. I recommend something more powerful, such as an iPad charger. I only gave it 4 stars because it has not built-in storage for the accessories, nor does it even include a carry bag to store them. So they will be lost in no time, and Im sure I am not the only one who feels that way.
