A:Answer The USB port on the back of the camera can be used with a Micro USB cable and power adapter (not included with your camera) to power your cameras rather than using batteries (for proper safety only use 5V/1A USB power adapters). The Blink Outdoor cameras feature a rubberized cover over the USB port. Removing this cover makes the camera no longer weatherproof. Furthermore, we cannot warranty devices connected to unreliable, third party power sources, or when weather protection is removed; therefore, it is important to have all devices kept indoors when connected to a power source through the USB port.
