My Kayak takes 8 psi max and this pump has no issues filling it. Only issues I have are my fault for not making sure fittings are tight or I don't have the Kayaks fill valve set properly.Fill up is pretty fast.Comes with a variety of fittings that should fit most anything.12V Cord is long enough.The display is too small (but usable) is my only gripe.Reliability? Not sure yet since I've only used it 5 times.

The device works well! Its size is a little bigger than what I expected, but it performs very well beyond my expectations—a good purchase.

This is a must have for quick paddle board trips! Takes so much time off prep and getting out on the water! Simple to use and so convenient!

This worked perfectly for me. I have only used it once with two inflatable paddle boards. I inflated them and deflated them. I used it with the lighter socket in my mini-van and found that you will get more power if the vehicle is running. It automatically stops at the PSI you set it to. Deflating was great because I never could get it to deflate all the way manually.

Does a good job. Pretty loud but better than hand pumping
