DC Barrel Plug Adapter, 2.1mm x 5.5mm Female to 1.3mm x 3.5mm Male, 18 AWG | RC-X1335C1
DC Barrel Plug Adapter, 2.1 x 5.5mm to 1.3 x 3.5mm | Part RC-X1335C1
The RC-X1335C1 is a DC barrel plug adapter that converts a 2.1mm x 5.5mm female socket to a 1.3mm x 3.5mm male plug — no soldering required. Use it to adapt an existing DC power supply to devices that require the smaller 1.3 x 3.5mm barrel connector. Built with 18 AWG wire and a compact 3-inch pigtail length.

Frequently Asked Questions
Q: What connectors does this adapter use?
A: The input (female socket) is 2.1mm x 5.5mm — the most common DC barrel size. The output (male plug) is 1.3mm x 3.5mm, a smaller connector used on many routers, cameras, and compact electronics.
Q: Do I need to solder anything?
A: No. This is a plug-and-play pigtail adapter. Simply connect the female end to your power supply and the male end to your device.
Q: Is the polarity center positive?
A: Yes. This adapter follows the standard center-positive convention. Verify your device's polarity before use.
Q: What wire gauge is used?
A: 18 AWG — suitable for most low-voltage DC power applications.
