It can support 3 paddle boards up to 20PSI. It has a fast but high pressure inflation feature with a cooling system to protect it from continuous use and overheating. It has a digital display where you can pre-set your pressure and watch the numbers as they go up. It only weighs 3.8lbs and can be taken anywhere. It has a max speed of 350L/min for the first stage and 40L/min for the 2nd stage. It auto turns off when pumping is complete to save battery. It comes with 5 different nozzles which are compatible with aquatic inflatables. It can be used on high pressure inflation mode for inflatable boats, yoga Mars, floating platforms, kayaks, canoes and so much more. And low pressure inflation mode for inflatable beds, yoga balls, inflatable swimming pools and so much more.

I've only used it twice so far and it blew up 2 paddleboards at a time with ease. I'm sure it could have done a third. I chose this pump because of it's lithium battery and that's the only way I plan to use it too. They are more expensive, but well worth the cost. I have an older car, and the cigarette lighter is 12DC V/120 W. KNOW what your wattage is!!!! Most of these pumps out there are between 140 and 180W with the 12 DC V. If your cigarette lighter is less wattage, chances are you will blow the fuse to the cigarette lighter.The battery indicator light is a little off, but I've learned to ignore it from other reviews. It always shows red unless it is fully charged and still plugged in. I have never seen the red bars go down as the battery goes down, and it does not flash red while charging either. The PSI set number is great and the thing shuts off like its supposed to. Just the fact that I don't have to manually pump 350 strokes is worth the money. The attachment fit my Bote Paddleboard perfectly.

Before buying a pump, I conducted a lot of research. There have been numerous concerns concerning overheating when loading multiple boards, as well as noise and time. Finally, I decided to try a new pump that had no reviews. I've already used it twice to fill up two SUPs. It took roughly 8 minutes to complete each board. I used that time to get everything else in order. The boards were ready once I was. Back-to-back, the pump handled them quite fine, and the noise level was as predicted. So far, I'm impressed.
