Key Features & Benefits

• Automatic Battery Backup: Seamlessly transitions from AC power to DC (battery) power during an electrical outage. An "Automatic Recharging System" ensures the pump recharges itself whenever it is plugged into a power source.

• Two Operating Modes: Custom tailor your battery life based on your needs:

  • Option 1 (Continuous): Push the button once for a strong, continuous air output lasting up to 12 hours.

  • Option 2 (Intermittent): Push the button for 5 seconds to activate a slower, intermittent flow that "shuts on and off every 30 seconds." This extends the battery life to an incredible over 25 hours.

• Smart Battery Protection: Equipped with a unique "Smart Battery Protection Unit" that prevents the lithium battery from entirely discharging, protecting the battery's lifespan and ensuring reliable performance during critical moments.

• Versatile USB Charging: Not limited to just wall outlets! This pump supports USB power, meaning you can run or charge it using a "power bank," "car" charger, or standard mobile phone adapter.

• Complete Setup Included: Comes with everything you need right out of the box, including dual airline tubing and two air stones, so you can set it up immediately.
