This is a nice little air pump. To test this I deflated one of my tires and inflated it with this pump. Here's what I think: Pros: It's portable and comes in a carrying case. It all fits in my glove compartment. The tube is just the right size to reach the valve stem cap no matter where it is on the tire, meaning you don't have to hold it while inflating. - It's pretty easy to understand. Outside. Just set your tire pressure, press the power button and it will inflate. Large display, easy to read in low light. Comes with a built-in flashlight. You have to worry about excessive inflation. The battery capacity seems to be quite good. It doesn't look like you'll need to charge it after each use. Comes with all adapters to inflate almost anything. Cons: It's a small device so inflation isn't very fast, but it's not too bad. My Tesla Model Y went from 20psi to 42psi in about a minute, which is normal for a small device. It's quite noisy, but that doesn't bother me. Overall I am happy with the purchase and recommend this air. Pump.
