I didn't use it many times this year, but every time I needed it (connecting it to a Citroen C3), it did a very good job inflating to 18psi in about 12 minutes. I found it important that it has a digital pressure gauge (target and current pressure while inflating).

The product does exactly what the company's description says. The inflation time of a large SAP is about 10 to 12 minutes with the detail that when it reaches the last bars, the sound of the pump changes, which is slightly louder and a bit more difficult due to approaching maximum inflation. Very satisfied with the product so far.

The only reason I give 4 stars is because it burns the fuse of the car's ignition as soon as it turns on. However, it works perfectly fine on older cars. I solved the problem by buying an adapter with clamps for the battery terminals. As soon as the problem occurred, I sent an email to the manufacturer and within a few minutes, I received a very informative response to any questions I had. In addition, the Zray 3-meter SUP inflates in about 6-7 minutes at maximum pressure! Very powerful!
