Hi, 
We do not sell power adapters or power cords separately. It is generally not recommended to use other power adapters and extension cables to power the camera, as this may affect its performance. For example:
  1. The material and length of the extension cable may cause the voltage reaching the Tapo camera to be lower than the voltage it requires to operate, resulting in some unusual behavior, such as the camera automatically restarting at night or getting stuck when panning and tilting.
  2. Using extension cords outdoors may also increase the risk of lightning damage, which may void your product's warranty.

For optimal performance, we recommend using the original power adapter and cord that came with the Tapo camera.

Best Regards
