6ft DC Power Extension Cable, 20 AWG, 2.1mm x 5.5mm, Black | HDCQ6
6ft DC Power Extension Cable — 20 AWG UL2464 | Part HDCQ6
The HDCQ6 is a 6-foot DC power extension cable with a standard 2.1mm x 5.5mm male-to-female barrel connector, built with a 20 AWG UL 2464-rated jacket. It's the go-to solution when your power adapter's cord just doesn't reach — adding 6 feet of clean, flexible extension without cutting or splicing. The black jacket blends into most installations and the molded strain-relief connectors keep the connection secure over time.

20 AWG vs. 18 AWG — Which Do I Need?
20 AWG is suitable for most low-to-medium current applications (typically up to 3–4A at 12V for a 6ft run). For higher-current devices or longer runs, consider our 18 AWG HDCX line for greater current capacity and lower voltage drop.
Frequently Asked Questions
Q: Is this center positive or center negative?
A: The cable passes through whatever polarity your power supply outputs. Polarity is not fixed by the cable itself.
Q: Will this work with my 2.1mm power adapter?
A: Yes — as long as your adapter has a 2.1mm x 5.5mm barrel plug output, this cable will extend it by 6 feet.
Q: Is a white version available?
A: Check our DC extension cable line for white and other color options.
Q: Need a heavier-gauge cable?
A: See our HDCX line (18 AWG) for higher-current applications.
