- After connecting with the power, the pump will be turned on, LCD screen is showing the reading pressure. Press the Pressure Unit button to select the pressure unit PSI or Bar. Use the Pressure Increase button (+) or Pressure Decrease button (-) to set your needed pressure. The range of pressure value is from 0.5 to 20PSI, (1PSI=0.0689BAR). Increasement is 0.5 PSI. After finishing the above steps, press the power On/Off button to start the pump.
- During the inflating process, you can be easy to increase or reduce the set pressure value without stopping the current pumping. Use the Unit button to switch the pressure reading in any time.

You can make sure the pressure is good before you disconnect the air hose from the chamber. When the application is 20PSI, the air hose connector will turn very tight when disconnecting. This is normal.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Took about 10 minutes to inflate my board to the recommended 15 psi
*by J***. on May 19, 2018*

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.

### ⭐⭐⭐⭐⭐ Great value for money and huge time saver
*by A***A on August 26, 2020*

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!

### ⭐ Low quality pump
*by D***D on October 10, 2019*

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
