Worth it for peace of mind to have in car
Works as described. Have used twice now. Takes a few minutes but will put air in tire. The cord is long enough to reach every tire.
Certainly loud when using
car must be on to use

Great true inflator
Great tire inflator also own a jumper pack in this brand, easy to use and great function to set the disired psi and auto shut off.

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.
