Review on 🔌 10 Pairs of 12V 5A DC Power Cable with Male Female Connectors for CCTV Security Camera Pigtail Power Adapter (5.5mm x 2.1mm) by Montez Vazquez

10 pairs for 10 euros! You get what you pay for! I bought these to make everything plug and play as my project needs to be taken apart to move from place to place. After laying out my project and testing everything to make sure everything worked as it should, I started soldering all my wires to assemble and shrink all my solder joints and everything was set up for my first test, when I connected the power supply. Setting the battery to 12 volts did not work! When I checked a fork, it got hot! Was replaced with another same one. It turns out they ALL have internal power supplies for a ground fault.
