Good inflator
Not the best one but works well!

Excellent Value for Price
I highly recommend one of these in your vehicle for emergencies. Don't fall for those handheld cordless ones you see on social media. Those will only inflate 1-2 tires before depleting. You have unlimited power for the plugins and it will inflate at least 4x faster.
The AstroAI is compact, lightweight and powerful for its price. Everything folds into its rectangular form factor for easy storage. The UI is simple and to the point. You can easily set the target pressure and it will auto stop. It's also a nice looking design with black and yellow which are common colors for power tools and emergency equipment.
If I were being picky, the 2 minor cons that you'll find in other brands are: no option to plug into wall outlet & doesn't come with a case or bag.

Great quality and design! Compact and easy to store in your car for emergencies.
These are handy to keep in your car for emergencies. Now that the weather is getting colder my tire pressure is going down on my car and I got tired of having to drive to a fas station and pay to put a bit of air in my tires (and often times those machines don't even work).
I like design of this one with the always on light and the compartment on the back to store everything neatly. It is small and compact so it doesn't take much space to store in your car. It also comes with multiple attachments for various uses.
I purchased this one as a gift for a white elephant gift for a family party coming up and hoping it will be a hit! With the great sale price it fit perfectly in the price range that was set.

Noisier than one I have
This does function the way it says it will and is easy to use. I tried it on 2 of my tires and did not like how it did not come off of my valve stem easily, compared to one I have. Seems it could potentially lead to stem damage over time, and when one goes out, your tire, obviously will not hold air (from personal experience). I sent it back and ordered another of the same one I previously purchased which is perfect and want to have a spare...just in case I need to loan one out or whatever. I cannot recommend this since I know there are better, quieter ones.

Great little air pump for the car! Easy to use and versatile!
This is a great little product! You set the psi limit for your object and it stops as soon as it is reached! No guessing about it. I have it in my care for emergencies but so far it has been useful for pumping up the grandkids tires, balls, floats, etc! It has several adapters for different things! Easy to use and fast!!
