Heavy-Duty 6ft DC Power Extension Cable — 18 AWG UL2464 | Part: HDCX6W

The HDCX6W is the white-jacket version of our industrial-grade HDCX6T, purpose-built for installations where aesthetics matter — think under-cabinet LED lighting, retail displays, and clean-install home automation setups. Same 18 AWG pure copper core and UL 2464-certified flame-retardant jacketing as the black version, delivering reliable power with minimal voltage drop over a 6-foot run.

Common Use Cases & Compatible Devices

Under-cabinet LED lighting and LED accent strips (12V, 24V)

Why Choose White?

White cables disappear against white walls, ceilings, and cabinetry — making the HDCX6W the preferred choice for clean, professional-looking LED and smart home installations. Same heavy-duty 18 AWG performance as the black HDCX6T, just in a color that blends in.

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 LED strip?
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: Is a black version available?
A: Yes — see the HDCX6T for the black 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.

Extension cable

Works great. Great price gave me the ability to move my wifi router where I needed and not be pulling hard on the cable.

Simple and Reliable

The cable does exactly what it's supposed to do. The build quality is solid, the finish is clean, and it works as advertised. There's not much more I could ask for from an extension cable.
