Product Overview

The AC-8666 is a specialized high-volume SUP (Stand-Up Paddleboard) and inflatable boat pump designed for watersports enthusiasts who demand rapid, reliable inflation at the dock or beach. Unlike standard tire inflators, this unit is optimized for high-volume, low-pressure applications — filling large air chambers quickly and efficiently. The dual-stage inflation system delivers high-speed airflow for the initial fill, then automatically switches to high-pressure mode for final pressurization up to 20 PSI — more than sufficient for most SUPs, kayaks, and inflatable dinghies. Multiple nozzle adapters ensure compatibility with all major SUP valve types including H3, HR, and Boston valves. Powered by a rechargeable lithium battery with DC 12V vehicle power backup, the AC-8666 can inflate multiple boards on a single charge. The digital pressure display lets you set your target PSI and walk away — the auto-stop function prevents over-inflation. A built-in deflation port makes packing up just as fast as setting up. Compact enough to fit in your dry bag, powerful enough for a full day on the water — the AC-8666 is the essential companion for every paddleboarding adventure.
