The air pump can be used either by plugging it in or using the rechargeable battery. The battery will automatically activate in the event of a power failure. The 2600mAh lithium battery is very useful for fish tanks during power outages or when leaving home.
The air pump has both a normal and intermittent mode. When fully charged, it can work continuously for 14-18 hours in normal mode and 25-28 hours in intermittent mode.
The set includes 1 air stone and 1 hose, and the air pump has dual air outlets, allowing it to run 1 air stone at the same time. The bubble stone effectively increases the oxygen content in the water, promoting the healthy growth and life of fish.
The air pump has a blue power light that indicates the battery level and mode. If the intermittent indicator light is on, the air pump is in intermittent mode. The 5 grid lights will be on when the battery is full.
The air pump has a noise level of ≦30dB and is designed to be energy saving, with a magnet driver and rubber pads to reduce noise. It is an excellent emergency oxygen pump for both freshwater and marine aquariums.
