The feeder can only connect to the app and enable remote network and video interaction when plugged in. When switched to battery power, the device will enter sleep mode and the app will not be usable (but the pre-set timed feeding schedule will still be executed at the set time). There will be no power switch or indicator light on the device. In this case, you can only manually press the button to test the feeding or wait for the feeding to be automatically dispensed at the time set in the app. It is recommended to use the plugged-in mode as the main mode in daily life to ensure full functionality and the best user experience.
All our automatic feeders are designed for safe and reliable operation in Hong Kong. Each feeder comes standard with a three-prong plug that fully complies with Hong Kong Electrical and Mechanical Services Department (EMSD) safety specifications. For greater power options, the feeders can also be conveniently charged via USB.
