Overview
This is a cordless, battery powered water fountain for cats, made of stainless steel with a 108 ounce (3.2 liter) reservoir and a rechargeable 4200mAh battery pack. It targets owners who want running water away from an outlet.
Because it runs on battery rather than a plug, it can sit anywhere in a home, including spots without a nearby socket. The stainless steel construction is easier to keep hygienic than plastic housings, which matters for a bowl cats drink from daily. No published run time is given in the listing, so how long a charge lasts between top ups is not specified.
- 3.2 liter / 108 ounce stainless steel reservoir
- 4200mAh rechargeable battery, cordless operation
- No outlet required for placement
- Stainless steel construction
Who it's for
Fits owners who need a fountain in a location without a convenient outlet, such as a hallway or a corner room, and who prefer stainless steel over plastic for easier cleaning.
Strengths and trade-offs
Drawn from this product's published specifications.
- Cordless, so placement is not limited by outlets
- 108oz / 3.2L capacity holds several days of water
- Stainless steel is easy to keep clean
- Battery needs recharging on a schedule not stated in the listing
- No pump flow rate or run time specification given
Performance notes
The 4200mAh battery is rechargeable, meaning it needs periodic recharging rather than running indefinitely like a plugged in unit. Stainless steel resists scratching and does not hold odor the way some plastics can over time, a common reason owners pick it for water bowls.
