Overview
A cordless water fountain from oneisall holding 74 oz (2.2 L) and running on a 4000mAh rechargeable battery, built around what the brand calls a SilentFlow pump for quiet operation near sleeping or easily startled cats.
Going cordless removes the need to route a cable near a water bowl, which matters in homes where the fountain sits away from an outlet. No attribute data or seller description were provided beyond the title, so capacity and battery claims come from the product name alone.
- 74 oz (2.2 L) water capacity
- 4000mAh rechargeable battery
- Cordless, battery-operated design
- BPA-free materials
Who it's for
Cat owners who want a water fountain in a spot without a nearby outlet, or who are sensitive to the hum of corded fountain pumps. Less useful for households with multiple cats needing a higher-capacity or multi-bowl setup.
Pros and cons
- Cordless design frees up placement options
- 74 oz capacity for multi-day use between refills
- Quiet pump aimed at noise-sensitive cats
- No attribute or description data on file to verify battery runtime
- Battery needs periodic recharging unlike a plug-in fountain
Performance notes
The 4000mAh battery is meant to power the pump for extended stretches between charges, with the SilentFlow design aimed at keeping noise low enough not to discourage cats that are wary of moving water.
