DC Power Barrel Plug Pigtail Set
This set provides three DC power pigtails with 5.5 mm by 2.5 mm barrel male plugs. Each pigtail uses pure copper wire cores for strong electrical conductivity. They are intended for connecting high-power power supplies or electronic equipment such as LED lighting. The cables are supplied new and ready for immediate use.
Build Integration and Cable Management
Each pigtail measures 30 cm or 11.81 inches, limiting reach to short-distance connections inside an enclosure. The wire outer diameter is 3.5 mm or 4 mm depending on the batch, and the core is 24 AWG or 18 AWG. The short length frees up space compared to longer cables but requires the power source to sit close to the device. No additional connectors are included.
Current Capacity and Usage Limits
The pigtails are rated for 4 A continuous current, suitable for typical LED strips and monitoring gear. They cannot handle loads exceeding that rating, so higher-power devices need a different cable gauge. The 5.5 mm by 2.5 mm plug must match the device jack exactly; mismatched sizes will not connect. Buyers needing longer runs or higher amperage should look elsewhere.

Questions about this item
How much current can the 5.5 mm x 2.5 mm barrel plug carry continuously without overheating?
The pigtail is rated for 4 A, so the 5.5 mm x 2.5 mm barrel plug can carry that current continuously under normal conditions.
Does the 24 AWG or 18 AWG copper core run cooler during all-day operation?
The 18 AWG copper core has lower resistance than 24 AWG, so it generates less heat and stays cooler when the cable runs at its 4 A rating all day.
What wire gauge and plug size must my existing power supply cable have for these pigtails to connect directly?
Your supply cable needs a 5.5 mm outer diameter and 2.5 mm inner diameter barrel jack, and the pigtail wires are 18 AWG for soldering or crimping.
