oneisall PW13 Wireless Cat Water Fountain, 2.2L, 3 Flow Modes, 5-Layer Filter

Technical overview

The cordless design lets you place this fountain where your pet drinks, without routing a power cord to the bowl. Its 2.2L capacity, three water-flow modes, and five-layer filter make it a practical choice for everyday indoor hydration. The integrated SilentFlow™ pump operates at a stated 20dB, helping keep the fountain unobtrusive in shared rooms.

• Capacity: 2.2L/74oz
• Power: Rechargeable 4000mAh lithium-ion battery
• Flow modes: Motion-sensor, intermittent, and constant flow
• Filter: Five-layer system with activated carbon, ion resin, Maifan stone, non-woven fabric, and high-density sponge
• Dimensions: 7 x 7 x 5.5 inches
• Included: Fountain, wireless pump, one filter and sponge, 5V/1A adapter, Type-C cord, user manual, and cleaning brush

The three-piece design separates into the pump, fountain body, and water tray for rinsing. A semi-transparent body makes it easier to see the water level at a glance. For cordless use, the motion-sensor mode runs a 30-second stream when a cat approaches within 2.6 feet, while intermittent mode runs for 15 seconds every 30 minutes. Constant flow is available when plugged in. The rechargeable battery is stated to run for up to 30–45 days per charge, with a full recharge taking 4.5 hours.

Buyers often point to quiet operation, straightforward cleaning, and battery life as useful everyday qualities. Feedback on the water flow is mixed, so the choice of mode can help tailor operation to the household’s routine and the pet’s interest in moving water.

Who it’s for

This fountain suits cat owners looking for a drinking station that can sit away from a wall outlet, as well as households with small dogs or other small animals. Its square footprint and 7-inch dimensions help when choosing a spot on a kitchen floor or in a living area. The motion-sensor setting is useful for a pet that approaches the fountain periodically, intermittent flow offers another way to run it between visits. If choosing between a basic water bowl and a circulating fountain, this model adds moving water, filtration, and a rechargeable cordless setup.
