that works 👍 The Momcozy camera does not have a built-in battery and always requires a 5 V USB power supply. However, you can easily operate it with a power bank, e.g. with the Bwoo 22.5 W 30000 mAh power bank.
Simply connect the camera to the power bank via USB cable - then it will run even without a power socket. With 30,000 mAh, the battery easily lasts for many hours of operation, depending on use.
Important: As soon as the power bank is empty or switches off, the camera also switches off. The camera still needs a permanent power source for continuous operation.
