Electric SUP Pumps

Does anyone have a good solution to inflating their paddle boards? I have been using a 12v pump to get it to 1.5 PSI, followed by a hi/low pressure K-pump to get to between 7 and 10 PSI, and then use my high pressure super pump to get the rest of the way to 15 PSI, and it is a chore. This year I added another SUP that tops out at 20 PSI, and am not looking forward to inflation time.

I have heard of a cheap mod to a Harbor Freight pump that can get your board to 15 or 20 PSI. I tried making one for my other 12v tire inflator, but it did not push very much volume, so it was taking longer than hand pumping.

Has anyone made anything similar, and have photos you'd be willing to post of your pump/adapters and how you built/connected them?

I have a rafting buddy with a 110 volt converter on his truck that will handle a small air compressor. With an air compressor my 16 foot cat takes about 15 minutes and a sup about 5 minutes. You just have to be careful not to over inflate.

Thanks Bighorn, do you have any photos of the connections? I have been thinking that this compressor connected to this valve adapter should do the trick.
The part I am missing is what series of adapters, connectors, duct tape and other shenanigans to place between the two in order to make a tight connection.
Ideas?

Building a compressor valve adapter. 6" or so of 1/2 in. x 10 ft. 600-PSI Schedule 40 PVC Plain End Pipe. One male compressor fitting. A little window caulk, gorilla glue or whatever applied thickly to threads of male fitting (enough to fill in between the compressor fitting threads and inside of pipe). Tap into PVC pipe and let set over night. Sand a tapered end opposite the compressor fitting. Done! Cost about $2.

Thanks, the tire inflation I had and the one I thought I was looking into had the threaded connector for a tire valve. I had not thought of connecting a compressor fitting, but that would generate a good deal of flexibility...the gears in my head are turning.

That beveled edge on the PVC seals against the valve well enough to fill a SUP to greater than 10 PSI? Cool!
