I ordered 5 outdoor plugs for my Arlo Pro 2 system and they work very well. As others have pointed out, the power cord is very snug on the camera, but this is necessary to keep water/rain off the camera. Simply line up the micro USB connector and press firmly into the camera. I found that attaching the connector to the camera first and then screwing on the camera mount before attaching to the bezel was the easiest option. Screwing in the screws is a bit fiddly, but it worked with a screwdriver with an attached bit extension and pre-drilling the starting holes.
