A battery-powered fountain that senses a pet within 4.9 ft and starts the flow automatically, or switches to a 20 second release every 20 minutes in Timer Mode. A detachable 4000mAh battery runs up to 40 days per charge in Sensor Mode with one cat, charging fully in 4 to 5 hours over a waterproof Type-C port. Water runs through a 5-stage filter and a stainless steel tray before reaching the bowl, and the pump stays under 30db.
