SUP Electric Pump Adaptor Compressor Air Valve Converter Multifunction Valve Adapter with 4 Air Nozzles for Halkey Roberts Valve, Stand Up Inflatable Paddle Board, Inflatable Bed, Inflatable Boat

I used this to inflate paddleboards before going to the river. Worked great!!!If you have an air compressor, this will save you a bunch of time. It normally takes about 9 minutes using the standard "Amazon special" electric SUP pump (https://smile.amazon.com/Tuomico-Electric-Inflatable-Inflation-Deflation/dp/B07KWZCJ59?ref_=ast_sto_dp). But with this adapter and the compressor, it took 4 minutes. 4 MINUTES!! Love that it saved me half the time. I have 4 boards, so it adds up.I'd definitely buy it again!Tip: use with (https://smile.amazon.com/AZUNO-Flashlight-Compressor-Accessories-Extension/dp/B07MBY35K6?ref_=ast_sto_dp)It has a pressure gauge built in to make sure I'm at the right PSI.

using the SUP adapter, and with the electric pump, it can only go up to 12psi, and I can hear air leaking around the ring. if i don't have the adapter on, my board is holding air just fine.

I screw it into my cheap tire air compressor. Fits great. Really helps me fill the SUP board faster.

Feels sturdy and all pieces came as expected!

Mainly bought this to get the Halkey Roberts fitting for my wifes stand up paddle board (which works great) but the other attachments should be useful too and appear well made.
