Wyze Cam Pan does not have a battery, so it needs be plugged into an external power source. Each camera comes with a 110V power adapter and a 6-foot USB power cord that can be plugged into a wall outlet or power bank.
You can also use the power cord to plug one Wyze Cam Pan into another to share the same power source. Simply plug the USB port end of the cord into the Wyze Cam Pan connected to the power source, then plug the micro-USB port end of the cord into the second Wyze Cam.
Wyze Cam Pan uses 5V 2A DC power through a micro USB port. You can use up to a 240V power converter with the camera. The power consumption is between 2-4 watts, depending on whether Night Vision is turned on.
