The best feature of the compressor is the battery.
The best part about the compressor is its battery, because you can use any USB C cable to charge it, and I can confirm that the battery will last a charge to fill up several tires from flat, although it is recommended to take breaks between each tire, as the motor does get hot and as such so does the hose, which could damage the hose due to it getting too hot, but other than that I am very impressed with the device and the convenience of not needing to have the car on, while having to deal with the 12V cable that other compressors use, and its a nice option that this compressor also includes that 12V cable in case you need it.

Doesn't last past a year
This product stopped working within 2 years. The initial pressure is registered but when it inflates it doesn't show you what the pressure is. You have to turn it off to see what it inflated the tire pressure to. The battery doesn't hold the charge long enough to inflate more than one tire then it's dead. We contacted the company since it's still under its warranty of 2 years and they totally assisted us with a replacement. They've got very good customer support.

Flexible power source - fast inflation
So far so good. It did the job quickly and was not as noisy as my last similar product. I like the case and the option to use the car lighter plug in should the battery not be fully charged. The heat level was minimal for the few minutes of use. Far too early to tell about longevity. My last product worked great for 2 years (about 5 hours of total use at most) and then caught on fire while using it. Time will tell with this one.

Perfect
Amazing! Bought because our tire pressure was always low. Quick and easy to use. Very convenient and fits in the trunk of the car. Not heavy at all.

Never know when you will need this.
Was looking for a tire inflator that works off of a USB port because the newer cars have eliminated the old cigarette lighter connection which was the power source for the inflators that I have. Well such inflators are available and this is the one I chose. Haven’t used it yet but I am ready.

Good build quality, solid features
So much better than the POS Ryobi unit this replaced. I like the attachments and the fact that you can set a specific tire pressure and inflate all 4 tires the same pressure. Battery life seems good. I thought the light was a gimmick, but it comes in handy. Easily inflates road bike tires to 100 psi.

Great value, don't depend on the 12v adapter though
Works well, not super fast but i can air up 4 truck tires from 18ish psi to 36psi in a reasonable amount of time and have been able to do that twice on a single battery charge. The 12v cigarette lighter adapter is significantly worse performance than the battery though. Other than that, the hose could be a little longer and the base could be a little wider, it will tip itself over while running. All in all a very good value.
