AC DC 12 Volts 3 Amp Power Adapter with 1 to 4 Splitter for CCTV Cam UL Listed

I had searched all over for something that can replace the many power converters I use for a project. Cuts the space usage to only one adapter instead of four! Make sure that your devices can accept 5V power. I can see where this would be helpful especially for CCTV cameras. I am using for something else. After searching for more than two months - everywhere, I came across many very expensive adapters all of which only had one connector. I could go out any purchase a rectifier at a great expense, but I do not need to get more than four devices powered up.
