Absolute Necessity!

Color: Orange, Number of Items: 1

So, the AstroAI arrived today. It was left in the mailbox because it was raining like crazy at the time. I had to go back & watch the videos again to learn how to use it. I'm like what does this thing at the top on the right hand side do. It allows you to screw in the hose & use it as a handle for carry; interesting considering it's small size. It fits into the palm of your hand. To my surprise, it comes with 2 hose attachments. One that screws onto your tires & the other one that snaps onto your tires. It also comes with the other smaller attachments. It comes charged. I tried it & it works great. Definitely worth the money because you don't want to be left on the side of the road or stranded at work coming out to find your tire has a slow leak, especially after working all day!

Works as intended, definitely recommend

Color: Orange, Number of Items: 1

Amazing little compressor. Super easy to use and can easily adjust the pressure maximum. The accuracy is fairly spot on and it is easy to carry and throw into a travel bag. Only complaint is that it doesn't hold a super good charge, you can maybe fill up about 2 1/2 tires before having to charge it up again.

Well worth the cost

Color: Orange, Number of Items: 1

I don't write reviews often, but this is about the best 20 bucks I ever spent. I bought this to keep in my motorcycle saddlebags for emergency roadside repairs. I didn't realize it had a flashlight in it and also a red flashing light which will be good if I'm ever stranded on the side of the road at night. It shuts itself off when it reaches the desired pressure, which is nice to set it and let it do it's thing since it is a small pump and takes a while. Keep your expectations low, as it is a tiny little unit and takes a long time to air up tires. But for what it is, it's perfect. I used it right out of the box to air up a tractor tire and it took several minutes, but it beats driving my tractor to the shop on a flat. This is an awesome little machine!

Small pump works as advertised. Needs longer hose

Color: Orange, Number of Items: 1, Color: Orange, Number of Items: 1

This is a physically small, light pump which matches my light duty application. I have a Solterra EV. While all cars need the tire pressure set properly, it is more important on an EV. I need to change the pressure by 2 or 3 pounds at a time on 4 tires to maintain 38psi. The pump performs beautifully. It pumps up to the 38psi I set on the pump and stops right on the button. I verified the pressure with my pressure gauge which agrees with the tire pressure monitor in the car. The pump performs accurately. The 5 button control on the device is implemented quite well making it easy to operate. It only took a minute to figure it out. My only complaint is the hose is too short. All the battery operated pumps I see have a hose that is too short. I purchased a longer hose from Amazon: https://www.amazon.com/dp/B0D2X52HY8?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_2&th=1 The longer hose allows me to stand instead of bend over if I am holding the pump. I can set the pump down on the garage floor even if the schrader valve is at the 12 o’clock position on my 19 inch tires. The hose is quite flexible and easy to use. I understand some rims have tight quarters around the valve. Make sure there is room around the valve for this chuck. Overall, this does what I need and consumes only a small space in my cargo area. Quite pleased.

Works great!

Color: Orange, Number of Items: 1

This works great! It is kind of bulky and big but I guess that's for the air. I use it for everything and it's portable to take on the go. Love all the attachments that it comes with. Very versatile. Display reads perfectly and correct and the inflation is super fast. Will definitely buy again!
