Question about HP Autozubehör Air compressor

I am absolutely satisfied with the price/performance ratio. The space-saving format was also a reason for the purchase decision. I use the device for off-road trips. However, you have to be aware that inflating a tyre with such a small device takes time. For 4 tyres 15-20 minutes - depending on how much pressure you have let off before. And for larger tyre diameters, even longer. So if I want to refill 4 times a day, I personally would definitely choose a more powerful compressor.
