AstroAI L4 Portable Tire Inflator - 150 PSI Cordless & Rechargeable Air Pump

Ease of use and accuracy

Excellent tool! I repair bicycles as a hobby so it gets used often and works awesome. Very accurate because I have checked against my digital tire gauge and it’s right on. First time I get my boat out for the season, tires are always low. The Astro worked great on car/boat trailer tires as well. This is the first time I’ve written a review on anything because I am that pleased.

Works Well

I got the AstroAI L4 to be able to maintain the air pressure in our automobile tires. My wife's car recently had a tire leak due to a screw in the tire. After repairing the tire I was able to inflate the tire to the proper pressure level within a couple of minutes. Also checked all the other tires (her vehicle and mine) and brought them up to the desired pressure level within 10-15 minutes. Nice compact product that is easy to operate.

Tire inflation.

Absolutely perfect exactly what I wanted.

Compact for easy portability, easy to charge and works as advertised.

I love this tool. It fits nicely in my E-Bike back bag and doesn't weight a ton. It is easy to use and works as advertised. The compressor stops when the desired threshold is reached.

Works awesome!

Portability is awesome! Fills tires faster than I thought. First use was 4 golf cart tires, 2 small footballs, and 2 utility cart tires. All were low so it was a good test. It is easy to use and love the digital readout is awesome!

Works as well as advertised You won’t be disappointed

Great value!

I have a very old car with a couple of tires that have very slow leaks. I don't drive much and new tires just aren't in my budget, so I decided to try this item. It works great! I do suggest reading the instructions first, even though it is very easy to use. It's just a matter of setting the amount of air you need, hooking it up to the tire stem, turn it on, and it does the rest! It automatically shuts off when it reaches the PSI you set. Highly recommended for women as well as men. No more searching for a place that has an air hose, and no more paying for air which should be free! It's also rechargeable with USB!

This is a nice portable pump at a great price. The connection for the tube is very durable unlike some other ones I’ve bought where they come loose. I would recommend this to keep in your vehicle in case of emergency.
