This portable aerator will not freeze up or jam. EASY CHARGING: Standard USB-C charger and cable.

Engel designers re-envisioned the live bait and minnow bucket aerator pump and have developed an all-new design that represents significant improvements in performance and reliability across a broad spectrum of usage environments. Forgotten are the bulky D-Cell batteries that wither quickly…especially in sub-zero temperatures. Gone are bulky power adapters and glitchy pump motors. Reimagined are the guts of a new tool built to endure all the challenges that today’s anglers bring to bear – long days, corrosive saltwater, frigid temperatures, oppressive heat, and lots and lots of moisture. Engel aims to make the dead pump=dead bait equation a memory we will soon forget with our keepalive bait tank pump.
