How about the Sensen Mini Air Pump?

Sensen mini air pump has strong air volume and low noise. Sensen's oxygen pump provides two modes, even if the power is off at home, you don't have to worry about not being able to add oxygen to the aquarium. It has a very simple and elegant appearance and is suitable. many scenarios. The Sensen long-lasting oxygen pump is designed with a large capacity lithium battery. It can last 26 hours without pressure when adding oxygen in intermittent mode. Although this oxygen pump is relatively small, its air volume is relatively large, and its air flow is also very stable. It is suitable for breeding ornamental fish at home and can also be used for wild fishing and oxygen transport. When there is a power outage at home, this oxygen pump automatically switches to battery power mode, which can effectively prevent fish from dying by manthan oxygen. However, it should be noted that when the remaining light is on, it should do so. be billed on time. Sensen's oxygen pump is made of suspended silent noise reduction technology, which can work without any resistance and without loss of work efficiency. It can produce air with high efficiency without producing excessive noise and will not impact the life of aquarists. There is a shock-absorbing silicone foot pad under the oxygen pump, which can absorb sound to a greater extent, effectively reduce the friction of the air pump, and make the noise even lower. This oxygen pump has two modes: continuous oxygenation and intermittent oxygenation. Directly press the switch button, and the switch zone will light up separately and it will enter the continuous oxygenation working state when the device is powered on, and oxygen. TherePump will enter 10 intermittent working states within seconds and stop within 10 seconds.
