12 ft 18 AWG 2.1 x 5.5mm DC Power Extension Cable, Heavy Duty, Black | HDCX12T
HDCX12T 12 ft 18 AWG DC Power Extension Cable is a heavy-duty inline extension cord designed for high-reliability low-voltage DC applications. Constructed with a pure copper 18 AWG conductor core and a flame-retardant UL 2464 jacket, this 12-foot cable delivers maximum current capacity with minimal voltage drop—making it ideal for commercial LED signage, CCTV security arrays, network hardware, and professional AV installations.
Important: HDCX12T is a passive inline extension cable. It passes through voltage and polarity unaltered from your original power supply. Always verify source voltage, load current, polarity, and connector dimensions before connecting your equipment.

Why 18 AWG Wire Matters
Standard consumer DC cables use thin 22 AWG or 24 AWG wire, which causes significant voltage drop and overheating risks under higher loads over long distances. Built with heavy-duty 18 AWG copper conductors, HDCX12T reduces line resistance, maintains steady voltage, and handles higher amperage demands across the full 12-foot run.
Frequently Asked Questions
What device connector size does HDCX12T fit?
It fits standard 2.1mm x 5.5mm DC barrel connections. It is not compatible with 2.5mm x 5.5mm jacks without a barrel adapter.
Does this cable change or regulate voltage?
No. HDCX12T is a passive inline cable. It passes the exact voltage, current, and center-positive or center-negative polarity from your connected power adapter straight to the device.
Is this cable UL Listed?
The outer cable jacket uses UL 2464 component-certified raw materials engineered for flame resistance and industrial durability.
