There are numerous clones of this type of compressor, but I found a good price at Vevor, so I went for it. Here is what I found:
Pros:
The compressor comes well packed. A storage bag is also included. It is perfectly sized to hold the unit and hose. The unit feels sturdy and is all metal, except the airfilter/intake cover, which is plastic. The compressor is very powerful. It inflates small car tires REALLY quickly, much faster than tire filling facilities at a gas station (here in The Netherlands at least). The tires of a VW Crafter van are also no problem at all! The included hose is also long enough to reach the back tires. But keep your engine running and place the power clamps properly, because it will draw a lot of current! The power cables are ok. They are quite flexible. But they're not something I'd run 45A through continuously. I guess combined with the 14.4V of today's cars and the max 13.8V input voltage of the pump it all fits.
The noise is quite tolerable, less than I expected.
Cons:
I suspect the pressure gauge is not very accurate and calibrated. it showed about 2.8 bar for my small car tires, which are at 2.4 bar tops. And for the van tires it showed about 5.0 bar instead of the 4.0 bar the compressor at the gas station showed. The air nozzles were missing. The gauge on my version doesn't have a deflation collar on the back like the manual states. Instead, it has a brass release valve on the pump itself between the air filter/intake and the carrying handle. This probably works as an overpressure valve as well, so you can you the unit for different purposes. There is no shutter near the gauge, so as soon as you switch the pump on, pressured air will flow. This is a bit cumbersome when you're working on the rear tires of a large van and there is 5 meters between the gauge and the on/off switch.
