6ft UL-Certified 18AWG DC Extension Cable (2.1mm x 5.5mm) - Heavy Duty, Black | HDCX6T
Heavy-Duty 6ft DC Power Extension Cable — 18 AWG UL2464 | Part: HDCX6T
The HDCX6T is an industrial-grade DC power extension cable built for applications where a standard 3-foot cord falls short. Featuring an 18 AWG pure copper core and UL 2464-certified flame-retardant jacketing, it delivers reliable power with minimal voltage drop — making it the go-to choice for CCTV installations, LED lighting systems, and professional AV setups.

Why 18 AWG?
Most consumer DC extension cables use 22AWG or 24AWG wire, which limits current capacity and increases voltage drop. The HDCX6T's 18 AWG construction supports higher amperage loads and maintains stable voltage delivery — critical for sensitive electronics and commercial installations.
Frequently Asked Questions
Q: What is the maximum current this cable supports?
A: The 18 AWG copper conductors support up to approximately 5–7A at 12V for a 6-foot run. Always verify against your power supply's rated output.
Q: Is this cable center positive or center negative?
A: The 2.1mm x 5.5mm barrel connector passes through whatever polarity your power supply outputs. Polarity is not fixed by the cable itself.
Q: Will this work with my 12V or 24V power supply?
A: Yes. Compatible with any DC power supply using a 2.1mm x 5.5mm barrel connector, regardless of voltage (within the cable's rated current limits).
Q: How does this compare to the 12ft HDCX12T?
A: Same 18 AWG construction and UL 2464 jacket — just half the length. Choose the HDCX6T when your power supply is nearby but needs a short extension.
Q: Is a white version available?
A: Yes — see the HDCX6W for the white version of this cable.
Q: Is this available for bulk or OEM orders?
A: Yes — we maintain high inventory for OEM and commercial projects. Contact us for volume pricing.
