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 cordless pump has been a game changer since switching over from my manual pump. I’ve used this to pump my bike tires and scooter tires, and the pressure gauge seems to be pretty accurate. The best part of that I can set a PSI target and when my tire hits it, the pump automatically stops.

I got this for my GFs sons HS graduation. He didnt have a portable air compressor for his vehicle. This will be nice if he ever has a low or flat tire. I gave it 4 stars because Im not sure how it will hold up over time.

Got this today. I immediately tried it and it now replaces the inflater Ive had for a few years. There are quite a few of these inflaters out there. I like this one for two reasons - it can be used with its internal battery or plugged into your cigarette lighter. The other reason is mentioned in the headline - the connecter is the push and clamp down type of connecter that you see on bike pumps. This is way better than the screw on type of connecter which normally gives me fits, trying to screw it on to the valve stem. My only concern is how long this device will hold a charge. It could spend a year sitting in my trunk until its needed. If the battery does drain down in that time, Im glad the adapter with a decent amount of wire is included. I gave the screw on type of inflater to my son - its his problem now!

Very convenient platform. I use it on my cars, trucks, and miscellaneous household items.

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.

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!

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

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.

This inflator is great. Lightweight but powerful enough to inflate a tire on my truck in under 8 minutes. Attach to tire, hit the trigger and walk away. The preset pressure will turn off the pump when reached. Easy to set pressure at what ever you want. Comes with lithium battery last will last over 10 minutes of continuous use. Need more? Pull the battery and plug in the included cigarette lighter plug and keep going. Big enough to be substantial, but small enough to be able to carry in your car at all times. Has very bright LED lights so can also be used in the dark or as a flashlight in a pinch. I get thumbs up on this one and look forward to keeping it in my truck for emergencies.
