Frequently Asked Questions

Q: What DC connector size does this cable use?

A: This cable features a standard 5.5mm outer diameter / 2.5mm inner pin DC female barrel connector — one of the most widely used DC jack sizes in consumer electronics, CCTV systems, LED drivers, and DIY power supplies.

Q: What is the benefit of a tinned wire end?

A: The pre-tinned wire end means the stranded copper conductors are already coated with solder, which prevents oxidation, reduces contact resistance, and makes it significantly easier to solder the wire to a PCB, terminal block, or connector. It saves time and ensures a cleaner, more reliable join.

Q: What current capacity does 18AWG support?

A: An 18AWG wire is rated to carry approximately 2.3–5A depending on insulation and installation conditions — sufficient for most DC-powered devices including CCTV cameras, LED strips, and low-power electronics running at 12V or 24V.

Q: Can this cable be used with a 5.5×2.1mm connector?

A: The 5.5mm outer dimension is the same, but this cable has a 2.5mm inner pin. While it may fit loosely in some 2.1mm sockets, for best contact and safety it is recommended to use it with 2.5mm ID matching equipment.
