9.8ft DC Power Extension Cable

The solarrely YCXGM-H3M is a 9.8ft 5.5x2.1mm male-to-female DC power extension cord sold as a 2-pack. It extends the reach of 12V devices such as routers, cameras, LED strip lights and Raspberry Pi boards when the original cable falls short. The standard DC5521 interface ensures a direct plug-and-play connection without wiring.

Thermals Noise and Power Draw

Copper conductors minimise electrical resistance and energy loss during power transmission. The PVC sheath operates reliably across a temperature range of -4°F to 176°F for long-term indoor or outdoor use. The cable supports a maximum of 36 volts and 36 watts at 3 amps. Shock-resistant construction protects the conductors from physical stress.

Upgrade and Replacement Value

This cord replaces a short factory lead that limits where a 5.5x2.1mm device can be placed. The 9.8ft length frees placement from outlet constraints for both temporary and permanent installs. Red and black colour coding simplifies polarity identification during setup. It is not for buyers who need a different barrel size or a higher current rating than 3 amps.

Questions about this item

How do I connect the 5.5 x 2.1 mm male-to-female DC connector to my router, and what is the common mistake?

Align the 5.5 mm outer and 2.1 mm inner diameters with the device port, then push straight in until fully seated; the common mistake is inserting at an angle which bends the centre pin.

What maintenance or replacement will the PVC-sheathed copper cable need after long-term indoor or outdoor use?

Inspect the shock-resistant sheath periodically for cracks or UV damage; replace the cord if the insulation splits or the connectors become loose, as copper cores resist oxidation but the PVC ages.

What limit appears first when the extension cord runs continuously at its 3 A, 36 W rating?

The 3 A current ceiling is reached first; sustained loads above 3 A or 36 W will overheat the 5.5 x 2.1 mm conductors before the 36 V voltage limit becomes relevant.
