oneisall PW13 2.2L Wireless Cat Fountain with 6 Filters

Why it makes sense

Some pet owners want a simple water bowl, while others prefer circulating water and flexible placement. The oneisall PW13 combines a 2.2L fountain with a rechargeable battery, so it can run without staying connected to a power cord. Its integrated pump and three flow modes make it easy to adapt the fountain to your home and your pet’s routine.

The battery-powered design suits indoor spaces such as a kitchen, living room, or bedroom. Choose motion-activated flow to start a 30-second stream when a cat approaches within 2.6 ft, constant flow for continuous circulation, or intermittent flow for 15-second bursts every 30 minutes. A red-light reminder indicates low water or battery, giving you a clear prompt to check the fountain. The manufacturer lists a battery life of up to 30–45 days per charge, charging takes 4.5 hours, and a Type-C cord is included.

Six filter-and-sponge sets are supplied, and each filter uses five layers to remove impurities and soften water. The fountain is made from BPA-free, food-grade polypropylene. Its 2.2L capacity and compact 6.5 x 5.5 x 6.5-inch dimensions make it a practical indoor water station for cats, small dogs, and small animals.

What to know

The pump is integrated into the fountain rather than connected by a separate cord, which keeps the setup cordless and avoids a loose pump cable in the drinking area. The semi-transparent body lets you see the water level, while the pump indicator’s red-light reminders help you know when to check water or battery. The included kit also contains a water pump, 5V/1A adapter, cleaning brush, and user manual.

Buyers highlight the quiet operation, rechargeable design, and straightforward cleaning. Feedback about water flow is mixed, so individual impressions of the stream vary. For a home choosing between a basic bowl and a more feature-rich fountain, this model brings filtration, adjustable flow, and cordless placement together in one setup.

Maintenance

The three-part design consists of the pump, fountain body, and water tray, and it can be disassembled in seconds for rinsing. This makes it easier to reach the main parts during routine cleaning without disconnecting a separate pump wire. Use the included cleaning brush to help clean the fountain, and check the visible water level as part of regular care. Replacement filter-and-sponge sets are included to support ongoing filtration.
