Fast inflation

We have inflatable fenders and SUP’s. I want to inflate these as easy and quick as possible. I have a built-in air pump in the cockpit. The small panel features an on-off switch and hose connector. So all I need to do is plug in the hose and switch on the pump. At 800 liters/minute this goes pretty fast. But it can be done even faster by using the compressed air of my scuba tanks. I had an adapter made. I can connect the standard water hose fittings or a hose with a pressure gauge. My SUP’s are now ready to go in 30 seconds.
