I’ve used this pump a number of times & it works well, even in our Oklahoma heat. I haven’t tried using it off of vehicle battery power, yet, but it has worked very well off of internal battery power to inflate our two BOTE iSUPs and it recharges quickly using iPhone charger. It probably could inflate 2 or 3 more without recharging. One thing I choose to do is use the pump up to the first 4 to 6 psi and then manually pump to 12psi. The reason I do this is because the electric pump seems to put more pressure on the inlet valve causing it to slightly dislodge from its housing. At approximately 3psi the pump goes into high pressure mode & at 10psi the hose begins shaking and gets very warm, indicating hot air is entering the SUP. I suspect this puts undo stress on the glue used to secure the inlet valve housing. Regardless, this pump saves my back since manually pumping the remaining amount is nominal compared to pumping the whole thing.

I was more than impressed with this powerful little SUP pump! Its small and compact making it easy to store and transport but can still inflate my paddle board up to 15 psi no problem (and can go up to 20 psi!).

A great pump I hope to use for years to come.

VORTEX PRO Rechargeable and Protable Electric Pump

It does the job! works well, easy to use, and works fast. I really have no complaints!

The battery lasted long enough to inflate both my board and a friends without slowing.

I used the 12V cable during a beach day and the auto-stop worked flawlessly.

It was easy to carry in the car and didnt take up much space.

The cooling feature kicked in after extended use and kept it from overheating.
