Ultra-long battery life, power-off switching, power-off auto-start, large and small air volume, intermittent work and low noise are the only reasons for you to choose it:

1. The fish tank is powered off for backup, concerned about the noise level (requires bedroom-level mute) and self-starting after power failure. The real self-starting after power failure (plug in the electric pump will not work, and the air pump will automatically start to add oxygen after a power failure) is not a power-off switch (plug in the electric pump to work, the air pump will continue to work after a power failure, and switch from external power supply to internal power supply).

2. Most of the claims on the market that the self-start after power failure can actually only be switched when the power is off, and it must be turned on at all times to realize the addition of oxygen after power failure. This oxygen pump can be plugged in and not turned on. After monitoring the power failure, it will be turned on. With other oxygenation equipment, the fish tank can always be oxygenated to ensure the safety of the small fish in the fish tank. The oxygen pump reduces the working time and increases the service life.
