SUNSUN AC/DC Rechargeable Aquarium Air Pump CP-100A / CP-200A

Keep your aquarium oxygenated even during a power outage with the SUNSUN CP Series AC/DC Rechargeable Air Pump. Designed for everyday aquarium aeration and emergency backup use, the CP-100A and CP-200A combine a built-in lithium battery, automatic power-outage activation, adjustable airflow and intermittent operating modes for reliable, energy-efficient performance.
When connected to mains power, the pump can operate as a regular aquarium air pump. If the electricity supply is interrupted, the automatic backup function switches the pump to battery power, helping maintain aeration when your fish need it most.
Key Features

Automatic Power-Outage BackupWhen external power is disconnected, the pump can automatically start using its internal battery to maintain aquarium aeration.
Long Battery RuntimeMultiple operating modes help balance airflow and battery consumption. Depending on model, airflow level and operating mode, runtime can reach up to 115 hours for CP-200A.
4 Adjustable Airflow LevelsChoose from 4 output levels according to your aquarium's aeration requirements while helping conserve battery power when maximum output is unnecessary.
Continuous & Intermittent ModesSelect continuous operation or one of the intermittent modes for longer battery runtime and flexible aeration.
Battery Level IndicatorBuilt-in indicator lights make it easy to monitor the remaining battery level at a glance.
Low-Noise OperationEngineered to reduce operating noise, making the pump suitable for home aquariums, bedrooms, offices and other indoor environments.
USB Type-C ChargingConvenient Type-C charging provides greater flexibility when recharging the pump.
