The Oneisall CW-01 is a 3.5L cordless pet water fountain with a 304 stainless steel basin and a rechargeable pump. It runs on three modes: a motion sensor that runs water for 30 seconds when a pet comes within about 39 inches, an intermittent mode that cycles every 30 minutes, and a continuous mode when plugged in. The stainless bowl resists bacteria and is dishwasher-safe, and the multi-layer carbon filter keeps water fresh. It suits owners who want a fountain away from an outlet or who worry about chewed cords; corded plastic fountains usually hold less water and lack a sensor mode. Owners rate it well overall, though some report pump and sensor reliability issues over time.

Owners like the cordless setup, the stainless bowl and the quiet sensor mode. The most common complaints are pump failures and sensors that stop triggering after a few months.
The Oneisall CW-01 is a cordless pet water fountain for cats with a 3.5L (118 fl oz) tank. It runs wire-free on a rechargeable battery, so it can be placed indoors or outdoors without a cord to tangle or chew. A water level window lets you check how much water is left.
The fountain is made of 304 stainless steel and food-grade ABS. The stainless steel is easy to clean and dishwasher-safe. A multi-layer filtration system with activated carbon filters removes impurities, hair and debris. Two replacement filters are included.
It has three water flow modes. Sensor Mode runs the water for 30 seconds when a pet comes within 39 inches (1 m). Intermittent Mode dispenses water for 30 seconds every 30 minutes. Continuous Mode gives a steady flow when the fountain is plugged in. The 5000mAh battery offers up to 60 days of standby, and the fountain keeps working during power outages. The pump operates below 30dB.
