Frequently Asked Questions

Q: What is the difference between the DC-2.1mm and DC-2.5mm connectors?

A: The DC-2.1mm and DC-2.5mm refer to the inner pin diameter of the connector. The 2.1mm is the most common standard for consumer electronics and power adapters, while the 2.5mm is slightly larger and used in certain equipment. Always check your device's power jack specification before ordering to ensure a proper fit.

Q: Are these connectors suitable for soldering onto a PCB or cable?

A: Yes! These are weld (solder) type connectors, meaning they are designed to be soldered directly onto cables, PCBs, or custom wiring harnesses for a secure, permanent connection. They are ideal for DIY electronics builds and repair projects.

Q: What is the maximum voltage these DC connectors can handle?

A: These connectors are rated for low-voltage applications — below 50V AC or 75V DC — making them well-suited for use with linear power supplies, LED drivers, small amplifiers, routers, and similar low-voltage devices.

Q: Is the gold plating purely aesthetic, or does it serve a functional purpose?

A: The gold plating on the copper base serves a very real functional purpose. Gold is an excellent conductor and highly resistant to oxidation and corrosion, which means these connectors maintain a clean, low-resistance contact over time — resulting in more stable and consistent power delivery.
