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.
