Overview
GOOIFUN's W3 is a cordless, battery powered cat fountain holding 88oz of water, recharged via USB-C rather than staying plugged in. It suits cat owners who lack an outlet near the water station or want to move the bowl around the house.
Most fountains on the market run continuously off a wall cord; this one runs on a rechargeable battery and only activates the pump when its motion sensor detects a pet approaching, meant to stretch battery life between charges. That tradeoff means flow is not continuous, so pets used to a constant stream may need a day or two to adjust. The carbon and sponge filters that ship with it need periodic replacement to keep the water moving and clean.
- 88oz / 2.6L capacity
- Battery powered, Type-C rechargeable
- 3 flow modes with motion sensor
- Includes carbon and sponge filter
Who it's for
Best for cat and small pet owners who want fountain water away from an outlet, such as on a counter or in a room without a nearby plug. Households with several thirsty cats drinking at once may find the 2.6 liter tank empties faster than they would like.
Strengths and trade-offs
Drawn from this product's published specifications.
- Runs without a nearby outlet
- Rechargeable via included Type-C cable
- Carbon and sponge filters included at purchase
- Motion sensor limits pump run time to save battery
- 88oz tank may not suit multi-pet homes
- Battery needs periodic recharging, unlike wired fountains
- Filters are a recurring replacement cost
Performance notes
The pump draws from the 2.6 liter reservoir through a carbon filter and a sponge filter before returning water to the bowl, and a motion sensor triggers the three flow modes rather than running the pump nonstop. Battery operation via the included Type-C cord means recharging on a schedule instead of a constant power draw, and the listing states a 2 year warranty.
