Shiruba Jumbo-1 Auto Rechargeable Air Pump

Shiruba Jumbo-1 Auto Rechargeable Air Pump for Reliable Aquarium Oxygen Backup

The Shiruba Jumbo-1 Auto Rechargeable Air Pump is a high-performance AC/DC aquarium air pump made for aquarists who need dependable aeration during both normal operation and power failure. It automatically switches between mains power and battery backup mode, helping maintain oxygen supply when electricity is interrupted. This makes it especially useful for stocked aquariums, breeding tanks, hospital tanks, planted aquariums, shrimp tanks, koi holding systems, and marine aquariums where stable oxygen levels are important.

Designed for aquariums up to 360 litres, this rechargeable air pump comes with two air outlets and a maximum air volume of 2 L/min × 2. In AC mode, the airflow is adjustable, allowing users to match aeration strength to the aquarium size and livestock requirement. In DC battery mode, the pump can run in intermittent pumping mode for up to 20 hours, giving fish and beneficial bacteria essential oxygen support during long power cuts.

The Shiruba Jumbo-1 is built for quiet, low-vibration performance with a noise level below 45 dB. Its high-quality plastic body and Taiwan-made construction offer long service life, while the rechargeable battery design removes the need for disposable batteries. The pump also uses an overcharging protection circuit to help extend battery life. It is a strong choice for Indian aquarium keepers who want a reliable emergency oxygen backup system for sensitive fish, expensive livestock, and high-value aquascapes.

How to Use This Rechargeable Aquarium Air Pump

1. Place the Shiruba Jumbo-1 Auto Rechargeable Air Pump on a dry, stable surface above water level or use a non-return valve if installed below aquarium water level.
2. Connect airline tubing to both air outlets, or use one outlet if only a single air line is required.
3. Attach air stones, sponge filters, breeder box air lines, or other compatible aquarium air accessories to the tubing.
4. Plug the pump into the AC power supply so it can operate normally and keep the internal battery charged.
5. Adjust the airflow in AC mode according to the aquarium size, fish load, and oxygen requirement.
6. During a power cut, allow the pump to switch automatically to DC battery mode for backup aeration.
7. Use intermittent pumping mode during long power cuts to extend backup operation up to around 20 hours.
8. Check bubbles from both outlets regularly to confirm proper airflow and oxygen movement inside the aquarium.

Care & Maintenance Tips

• Keep the pump in a dry, well-ventilated area away from splashing water and aquarium spills.
• Use a check valve on each airline to prevent water backflow into the pump.
• Clean or replace air stones when bubbles become weak or uneven.
• Inspect airline tubing regularly for cracks, blockages, or loose connections.
• Keep the pump plugged in during normal use so the rechargeable battery remains ready for power cuts.
• Do not cover the pump during operation, as airflow around the unit helps maintain performance.
• Test battery backup function periodically to make sure the pump switches correctly during power failure.
• Avoid placing the pump directly on hollow wooden surfaces if vibration noise is amplified.
• Use both outlets with suitable air stones or sponge filters for balanced oxygen distribution in larger aquariums.
• Do not open or modify the battery compartment unless serviced by a qualified technician.
