Review on 🔌 High-Quality 18AWG Copper Strands: 10 Pairs DC Power Pigtail Cable Wire for CCTV Security Camera and Lighting Power Adapter (2.1mm x 5.5mm, Ultra Thick) by MILAPEAK by Brenda Hofheins

While I won't get into the "true 18" controversy, I'll just give one real example. I hooked one up to 18V at 1.5A to test (27W) before hooking up a bunch to my setup. The length of the cable run was 3 feet, with the first 2 feet of 16 gauge wire connected to the 6" pigtail of the connector and the second 6" connected to the male side of the connector pigtail. * be rated for about 10A at 12V, or about 120W, or just over 6A at 18V. At 27W, the connector immediately became very hot to very warm. At 50 watts? Forget it, it's a fire hazard. So no matter what gauge of stranded wire you're calling between the wire and the connection points, I wouldn't buy it unless you're using some VERY low-power devices to connect it. Especially since I'm assuming you're making connections longer than 3ft (capacity roughly halves for every doubling of run length).
