NFESOLAR 4W Solar Aerator for Pond — 2200mAh Battery, 2 Air Stones & 3 Modes

NFESOLAR 4W Solar Aerator is a waterproof, solar-plus-battery pond pump that supplies oxygen to small ponds and stock tanks with three operating modes and two air stones.

Keep water moving and oxygenated without running mains power: this compact solar aerator uses a 4W solar panel to run during daylight and an internal 2200mAh rechargeable battery to continue operation at night. Built for outdoor use, the unit’s waterproof design and included air stones work together to improve circulation and reduce stagnation in small ponds, tanks, and water features up to about 80 gallons.

How does the NFESOLAR aerator keep water healthy in ponds and stock tanks?

The aerator increases dissolved oxygen and circulation by producing continuous bubbles and surface agitation, which helps reduce anaerobic zones and supports aquatic life. Its two air stones distribute bubbles across the pond so oxygen is more evenly mixed rather than concentrated in a single spot.

• Two air stones for broader oxygen dispersion
• Continuous operation day and night with solar charging plus battery backup
• Waterproof casing suited for outdoor placement

What are the operating modes and when should I use each?

You can choose between Strong Bubble, Soft Bubble, and a 10-second on/10-second off intermittent mode. Strong Bubble is for hot weather or higher oxygen demand; Soft Bubble is quieter and uses less energy; 10S ON/OFF stretches battery runtime during low-sun periods or colder months.

• Strong Bubble: maximum airflow for warm seasons
• Soft Bubble: quieter, lower-consumption option
• 10S ON/OFF: conserves battery when sunlight is limited

How long will it run at night and how reliable is the battery?

The built-in 2200mAh battery stores solar energy and can power the aerator after dark; on Strong Bubble mode it can operate more than 16 hours when fully charged. Actual runtime varies with sunlight, seasonal conditions, and mode selection, but the combination of panel and battery provides dependable nocturnal operation for small ponds.

• 2200mAh rechargeable battery for overnight use
• Solar charging during the day replenishes the battery
• Runtime depends on sun exposure and chosen mode
