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 product is really handy, and easy to use. Its nice to be able to carry this to places that are unreachable by other air compressors, like when my lawnmower tire loses air but is still out in the yard. It works fast, and it shuts off automatically at the prechosen PSI. Just attach it and push a button, and it does the rest! Im not sure how it would hold up to being dropped, but hopefully itll prove durable. Thus far, I like it!

This is a great tire inflater. It comes with a battery, a 12 volt adaptor and a couple of adaptors for inflating smaller objects. The hose has a clamp on type connection for tires. I really like the 12 volt insert, it basically is the same size as the battery and slides into the tool just like the battery and has a long cord with a cigarette lighter type 12 volt plug, so you can switch between the 12 volt or battery very easily and the 12 volt cord wraps around the 12 volt adapter and has a space for the plug to sit in. In the pictures I included you can see the battery on the left and 12 volt adaptor on the right. The inflator itself is digital, so you can change between air pressure units, as well as set a desired target for inflation. I set it to 40 psi and hooked it to one of my tires, which read 36 psi and then pressed the trigger and when it started I set the unit down and it inflated the tire until it reached 40 psi. It has some presets for other tires as well or you can set your own target. It also comes with LED lights in the nose of the the tool which I can see would come very useful in the dark. The battery charges with a USB C charging cord so you could charge the battery right in your vehicle (most vehicles today). This is a superior inflation tool to other hand held trigger units I have used, it is digital, has both 12 volt and battery and hands free. The only negative I would have for this is it is on the larger size and a case would have been really nice. I was really torn as to whether this should be 4 or 5 stars, ultimately deciding on 5 stars, while a case would have been nice, it comes with both battery and 12 volt adaptor, digital and hands free while charging. Other similar big name units can cost $30 - $40 and they dont come with the battery which can add a lot to the cost.

This tire inflator is really good for keeping in the trunk of your car, or in your garage to inflate items in case of an emergency, or larger items, such as pool, toys, or other items that need to be filled with air. We also use this to inflate the tires on our bikes. Comes with various attachments for inflating, sports, equipment, like balls, or the more blunt tip for inflating, pool, inflatable’s, or floating rafts.

I used this for the first time recently and it was much easier and quicker than dragging out my pancake air compressor, 50 foot air hose, extension cord, and then waiting for the old compressor to fill itself with air. This thing on the other hand was so easy to use, I just set the desired pressure, connect to the tire and hit the start button and then it shuts off when it gets to the pressure limit. I was not sure how long it would last on a single charge but I needed to air up two trailer tires and 4 lawn mower tires. It easily handled the trailer and the mower so then I topped the 4 tires on my other mower, my car, and my wife’s car. Keep in mind that none of these tires were flat to begin with, but it was able to handle all of that, 2 trailer tires, 8 lawn mower tires, 8 car tires and still had battery life left. Plus if the battery dies, it has a 12 volt cigarette lighter plug you can use instead of the battery. It is lightweight, easy to use. I was quite impressed.

I didnt realize that such a tool existed! I have four cars and on any given week at least one of them has a tire that could be topped up to proper pressure. This is the perfect tool for getting this job done! It works flawlessly. There are a variety of modes depending on whether youre inflating a bicycle, car, etc. It also can change to different pressure units. I LOVE this pump!

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 like this tire inflator so much that I bought a second one for my SUV. 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.

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

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.
