Overview
The oneisall PF14 combines a 5L timed food hopper with a 3.5L gravity water reservoir in one USB-C powered unit, giving cat owners portion controlled meals and a standing water supply from a single base.
Automatic feeders solve the same problem in different ways: some run on a timer, others on portion count, and a few pair feeding with water in one footprint to save counter space. This unit falls into that last category, stacking a stainless steel food bowl and water bowl onto a shared base rather than selling them as separate devices. At 8.5L combined capacity it is sized for one cat's daily routine rather than a multi-cat household or a long trip away from home.
- 5L dry food hopper plus 3.5L gravity water dispenser
- 36 cup total capacity across both
- USB-C powered, no batteries required
- White, modern styled housing at 22.6 x 6.46 x 13 inches
Who it's for
Fits an owner who wants scheduled portions and fresh water available without buying two separate gadgets. A single cat on a regular feeding routine is the target use case; households feeding several cats from one station will need to watch for one animal guarding both bowls.
Strengths and trade-offs
Drawn from this product's published specifications.
- Combines food and water in one base
- Stainless steel bowls are dishwasher safe
- Scheduled portion control for dry food
- 2 year manufacturer warranty
- No battery backup, corded power only
- 8.5L total capacity suits a single cat
- USB-C cable and adapter add another cord to manage
Performance notes
The hopper meters food on a schedule rather than free feeding, and the stainless steel bowls sit on a base described as anti-tip and built to keep food and water from cross contaminating each other. It runs on USB-C power with no battery option, so it depends on a live outlet nearby. Both bowls are listed as dishwasher safe, which matters more for a wet food or water setup than a dry food only unit.
