## Features

- 【For Standard 5.5 × 2.1 mm DC Ports Only】This DC extension cable is designed only for devices with a standard 5.5 mm outer diameter and 2.1 mm inner diameter round DC barrel power port. Please check your original plug size before purchase. It is not compatible with 5.5 × 2.5 mm, 4.0 × 1.7 mm, 3.5 × 1.35 mm, 2.5 × 0.7 mm, USB ports, AC 3-prong plugs, or proprietary/non-round camera connectors with locking tabs, extra teeth, or special shapes.
- 【Check Plug Size & Port Clearance】Before ordering, confirm both the 5.5 × 2.1 mm barrel size and the space around your device port. This cable uses a standard 5.5 × 2.1 mm plug, but installation depends on physical clearance. The plastic connector housing is approx. 11.55 mm wide and may block recessed, narrow, or covered ports. The metal plug tip/insertion section is approx. 1.55 mm long. Even with a compatible port, limited space may prevent full insertion. Please verify fit before purchase.
- 【For Compatible Low-Voltage DC Devices】Use this cable to extend power when the original cord is not long enough or the outlet is not nearby. The DC power extension cable is suitable for compatible DC-powered cameras, routers, LED strip lights, DVR/NVR systems, and other devices with a standard 5.5 × 2.1 mm DC input rated 24V or lower. Voltage drop may occur over long runs or high-current setups.
- 【Power Only, Not for Data or Video】This is a DC power extension cable only. It does not support data transfer, video signals, audio signals, USB communication, syncing, or display output. It is also not for USB-powered cameras or devices with non-round, locking-style, extra-tooth, or special-shape connectors. Included nail-in clips and cable ties help secure the cable during installation.
- 【Flat Cable for Indoor & Covered Outdoor Routing】The low-profile flat cable routes neatly along door frames, window edges, walls, furniture, corners, and baseboards with less visible bulk than round cables. Multiple length options are available for indoor or covered outdoor setups, such as garages, patios, porches, doorways, windows, and exterior walls. For outdoor use, protect connection points from heavy rain, snow, and standing water.
