Here’s something I researched , a power bank can work with this camera. The product description states this wireless indoor camera comes with a 2500mAh rechargeable battery that provides 90 days of non-stop power. Using a power bank can provide additional charging options for the camera when not connected to a power source. PS. (1. Run the power bank fully charged,plugged into the camera in off position. )( 2. After power bank runs out the camera will turn off. Unplug the power bank then switch the camera to on position,( 3.It will reboot and come back online.Now you’re running on the camera battery. Repeat when the camera runs out. If you have two power banks you’ll be all set .
