These are a standard DC power connector used on things such as the Arduino and cctv cameras. These connectors are the same as those at a lot of electronics shops just without the big price tag or over rated packaging.

These connectors came well packaged. The black plastic part screws off to reveal the connections inside. I used this to make a test lead setup for a power supply as seen in the pictures. I was able to easily solder onto the metal for a secure connection. There were 10 pcs in the package, each one was individually wrapped. No issues with this product, it was exactly what I expected.
