Technical Definitions
- Dual Power Supply
- A system where the device primarily runs on AC power (via a wall outlet) but automatically switches to a secondary battery source during a power failure to maintain the feeding schedule.
- Capacity (Liters vs. Cups)
- Storage volume varies by kibble density. Generally, 1 Liter of volume accommodates approximately 4 to 4.5 cups of standard dry pet food.
- App Connectivity
- Refers to the method by which the feeder communicates with a smartphone. Most modern "Smart" feeders utilize 2.4 GHz WiFi networks, though some 2026 models support dual-band (2.4/5 GHz) connectivity.
