We used this pump on battery to inflate a double kayak, and were happy with how quickly it did the job. The preset pressure shutoff is a great feature. Light and easily transported. We are happy with this purchase

Perfect and compact. Works efficiently and compatible with the ROC paddleboards

The tool itself is prety good. Convenient you can change it at home and use later. The only problem l have is it doesn't say how to properyuse thee sockets to delate the kayak, mattress or anything else. Deflation takes the most time in my case. No complain on inflation though.

I use this to top of my rigid inflatable, which has a smalleak and needs to airto betopped off once a week orso.l like the automatic sensor. Once you've set the desired
presure, you just connect it, press the button and wait for it to shut off when it's done. it's prety quiet, compared to some l've heard.
One charge of the battery lasted me all summer.

Strong pump but i don't think it willl 4 boards as advertised. 3 boards is pushing it. reasonably priced. Purchased at end of seaon. The big challenge wil be end of spring 2025 when i will be using it on multiport's several times throughout the summer. l will update then if necessary.
