With this intelligent pet feeder, you can precisely program the times at which a specific amount of food (in portions of approximately 20 ml) should be dispensed. You now have full control over the feeding times and exact portion sizes for your pets. No more late meals for your cat or dog when you come home late, and you no longer have to ask your neighbors to feed your pets when you go away for the weekend. This pet feeder features a removable food container that can hold up to 3.7 liters of dry food. A sensor notifies you with an LED display and a push notification on your phone when the container is empty, so you know when to clean and refill it. A second sensor checks at each feeding whether food has actually been dispensed. If the container is completely empty, jammed, or tipped over, you will receive a notification that no food has come out. The feeder is powered by a 5V 1A USB charger and a USB-to-Micro-USB cable. To ensure your pets receive their food even in the unlikely event of a power outage, you can add a power bank (not included) as a backup. The feeding schedule is stored in the product, so your pets will receive their food at the designated times even without a Wi-Fi connection.
