Tuomico 20PSI High Pressure SUP Electric Air Pump,Dual Stage Inflation Paddle Board Pump for Inflatable Stand Up Paddle Boards, Boats,Kayak,12V DC Car Connector

this pump works great! . portable, inflates my paddle board in minutes compared to the hour long nightmare hand pump. there are several different attachment's, so this is also great for blowing up pool floats as well. Blowing capacity is top notch. auto shut off feature works well. would highly recommend!

It arrived on time, and performed as advertised. I am extremely pleased.

Very fast initial inflation to 1 PSI. Does not switch from low pressure to high pressure automatically. Here's what happens. Set pressure to say 3.0 PSI. Start pump. Pressure goes to 1.0 PSI using high volume pump and stays there with pump running continuously. Never reaches 3.0 PSI and never stops. However if, with pump still connected, one turns the pump off then on, the high pressure pump engages, the pressure goes to 3.0 PSI, and then the pump shuts off. The only reason I gave it 2 stars instead of 1 star is that it really inflates fast to 1.0 psi, and then more slowly but nicely to 3.0 PSI. If it actually switched automatically from high volume to high pressure I would have given it 5 stars. In process of returning it. What a shame.I had Amazon replace with same item. Exactly the same behavior. However, the replacement came with a manual (missing from the first one). So, after low pressure pump reaches 1 psi, manual says hold power switch down for 3 seconds and it goes to high pressure just fine. So I'm upping my review to 4 stars only because it did not do quite what was claimed, but really works well otherwise.

Worked for awhile then when using after 30 seconds or so it makes a loud noise like the motor isn’t working and then doesn’t pump air, have to turn off and on to work. Guess I got sent a defected pump i would recommend buying

It works well.

Works as advertised. I wish the cord was a little longer as I plug into the socket in the back of my Forester. Getting around my inflatable kayak is a stretch. You can select PSI or Bar and set the required pressure. It will cut off at the set limit. It also has a deflate outlet. So far so good!

I got this for my colorado pontoon. I got two others that weren't satisfactory and returned them. This works very well. I set it for 2.5 psi and that's where it stops automatically. It seems to be two stage. It will run for a while and after a while it run at a higher speed until the desired pressure is reached.

It shuts off when it hits its target PSI. It's awesome! I can be fumbling around, finding all my accessories and preparing for the water while my SUP just fills itself right up.My SUPs say right on them "do no use electric pump," so I put this purchase off for a long time. Boy was that a mistake. I used my SUPs way more this summer than before, because I didn't have to stand around sweating while I pumped up my board with my muscles burning. AND my manual pumps couldn't ever get my boars anywhere near 15 PSI. That being said, I only ever set this to 12 PSI, because I'm nervous about popping my (very expensive) SUPs. But 12 PSI is plenty.I can't say enough about how much I love this pump.
