AquaMiracle Lithium Battery Powered Dual Outlet Aquarium Air Pump | USB Rechargeable, 40–120 Gallon Tanks

Powerful aeration for large tanks and uncertain times

Designed for 40–120 gallon aquariums, this AquaMiracle air pump delivers steady bubbles with two outlets and a compact, energy‑efficient profile. Each outlet supports adjustable flow (11–24 GPH per outlet) to help you balance surface agitation across your tank.

With a simple flow control button, you can fine‑tune the fizz without creating excessive noise or splash. The unit runs at 2W and works with both AC and DC power, giving you flexibility for everyday use and extended power outages.

Power you can rely on

The built‑in 2600 mAh lithium battery is USB‑rechargeable, so you can charge from a wall charger, power bank, or laptop. In standard operation, it can run about 20 hours on a full charge. If you enable periodic operation, the runtime can extend to roughly 30 hours, and up to 40 hours at low output.

• Automatic AC/DC switching ensures a smooth transition if mains power fluctuates or fails.
• Two outlets with independent flow adjustment let you customize aeration for each tank section.
• All essential components are included: 2 x airline tubing, 2 x air stones, 2 x check valves, 1 x T valve.

Practical uses and tank compatibility

This whisper‑quiet bubbler works with both fresh water and saltwater setups. It serves as a standard aerator, a reliable backup during outages, and an effective live bait aerator for fishing.

• Emergency aeration during power cuts to help maintain agitation and oxygen exchange.
• Live bait or specimen aeration when you’re away from the tank.
• Compact and portable for transport between tanks or venues.

Choose AquaMiracle for flexible, off‑grid aeration options that align with your tank size and routine. While results can vary with fish load and environment, the design emphasizes dependable performance and easy setup.
