SeamaxMarine SUP20D Electric Air Pump for Inflatable Paddle Board, Max 20 PSI, Additional Fittings Included, Pro Edition Built in Temperature Sensor and Voltage Meter Support Inflation and Deflation

Fresh out of the box the product worked as desired/expected. Took about 10 minutes to inflate my board to the recommended 15 psi; shut off automatically and the 15 psi setting was stored in pump memory for next use. Used the alligator clips, and adaptor provided, hooked up to car battery. Yes, 10 minutes is about the same time it would take to inflate by pump but, obviously, without physical effort on my part. This is what will allow my wife to take our board out and not need my assistance. Additionally, the board felt more firm which tells me maybe I wasn't getting a full 15 psi by pump, despite the pump's gauge reading. Did not find noise of operation to be an issue. Only 4 stars for now as the cynic in me needs to learn the longevity of this pump/brand, as so many others seem to have problems/short life spans.Update: After having used this pump, several times now, I'm boosting my rating to 5 stars and am very happy with its performance.For those who ask if the Seamax pump will work with their particular brand of board--it's not the manufacturer of your board to consider but the valve connection. Take a look at the hose connection from your inflation hand pump; if it's the same as the connection on the Seamax then it should work just fine.

We've been using inflatable kayaks for the past few months and the entire process of pumping them up before a day on the water was TOUGH. Our backs would be sore and we'd be incredibly sweaty (Arizona) - it really wasn't a good start to what was supposed to be a relaxing day.After a bunch of research, I settled on the SeaMax - it was reasonably priced and had some pretty good reviews, although a few bad ones. We have been incredibly pleased with it!We can pump both kayaks in about 20 minutes - it only takes that long because there are so many chambers and we have to change out the attachment a bunch. After 6 uses, it has never overheated on us, unlike some of the other reviews.I gave 4/5 stars for ease of use, because it can be a bit of trial and error on which attachment and O-Ring to use (we rented a bunch of times so the boats weren't always the same), but now that we've purchased, that won't be an issue!

Where I bought this there were many people mentioning the time it takes to fill an SUP so I purchased an inexpensive AIRHEAD air pump. This fills the SUP up with air to about 0.9PSI.Then I connect the Seamax pump to get up to 15 PSI.This strategy works well.My issues: The Seamax is loud. To take the SUP from 0.9 to 15 PSI takes about 15 minutes, which was expected. But you need ear plugs or just walk away while it runs.The rubber pads on the bottom of the pump will stain your SUP. Don't set this on your SUP or you'll have 4 suction cup stains on your SUP.The pump is low quality. It worked well the first 2 times I used it. Same day, filled 2 SUPs then didn't use it again for about 4 weeks. In that time I stored it in my garage.The next time I tried to use the pump it wouldn't turn over. I hand pumped the SUPs that day.Several days later I tried the pump again and it still wouldn't rotate the pump. I could hear the electric motor trying but the pump was stuck.Using my lungs I blew air backward into the pump. This moved the piston enough that the electric motor could get it moving and keep moving.So now I have to give the pump a little blow job every time I want to use it.It does require a high amp 12V port. I blew the fuse in my boat and had to make an adapter to put on the battery directly.Overall I don't recommend this pump. I'm looking at getting an adapter to a schreader valve (bike tire) and use an automatic car tire inflator

The media could not be loaded. I have no idea why there are no real reviews on this Pump....it is great. This is after buying 2 other pumps that were twice the money and both awful. I sent both back.This pump comes with the Halkey-Roberts Valve Adapter for my Isle SUP...I attached the valve, plugged it into the 12v, started the car, set the pump on 15 and ate a sandwich (sandwich not included). About 10-12 minutes later it shut off at 15psi....That's whatSUP!!!!It was very quiet compared to the other pumps I tried. (It is loud in the video due to the closeness of my phone)I gave 4 instead of 5 stars because there is no deflation mode which is always nice...and It could have used a better quality hose..

I have had a chance to use this air I pump as of yet . Hopefully I will sometime soon as I plan to do some fishing in the near future. I will say I was surprised by how much it weighed. Not in a negative way either.It seems to really be made . The hose that comes with it is nice and heavy which is a huge improvement over the last air pump I purchased. I think this will out last me.

For the price I wasn’t expecting much but holy crap did it show out. Super lightweight, easy to use, shuts off automatically at the PSI/BAR you set it to. It’s not extremely loud, about as much as to be expected which is nice. The huge plus here though, a 10.5 foot board that’s 6” thick, took 8 minutes to fill from flat and rolled up to completely solid and at the appropriate PSI. It takes us usually around 45 minutes to air up one board because it’s so hot where we are. The manual pump also takes so much out of you that it’s hard to really enjoy the day after. This thing is an absolute life saver!!!
