Frequently Asked Questions

Q: What devices are compatible with the 5.5×2.1mm DC male plug?

A: The 5.5×2.1mm size is one of the most widely used DC barrel connector standards. It is compatible with most CCTV camera systems, LED drivers, routers, modems, Arduino power supplies, and other consumer electronics that use a standard DC barrel jack.

Q: How do I attach wires to these DC male plugs?

A: These plugs are solder/weld-type connectors. Strip your wire, thread it through the strain-relief housing, and solder the positive wire to the center pin and the negative wire to the outer sleeve terminal. Use heat-shrink tubing for a clean, protected finish.

Q: What is the maximum voltage these plugs support?

A: These connectors are rated for voltages below 50V DC (3C standard), making them suitable for typical low-voltage applications such as 5V, 9V, 12V, and 24V DC power setups.

Q: Are these male or female connectors?

A: These are DC male plugs — the type you attach to the end of a power cable to plug into a female DC jack or socket on your device or power supply.
