DC Power Extension Cable

The eForChina 2m 22AWG cable extends a 5.5 x 2.1mm DC power connection between a supply and a laptop. A female jack on one end mates with a male plug on the other, adding reach without changing polarity. The TPE jacket remains flexible in typical indoor temperatures.

Replaces worn or short factory leads

Swap this in when the original laptop power cord has damaged insulation or cannot reach the outlet from the desk. The 22AWG conductors handle the same low-voltage DC current as the stock cable, so the upgrade is worthwhile whenever extra length solves a placement problem.

Steady output over the full run

The copper cores maintain consistent voltage delivery across the two-metre span during continuous charging sessions. TPE sheathing resists kinking and abrasion when the cable is routed behind furniture or across walkways, keeping resistance stable under daily movement.

Questions about this item

Will the 5.5 x 2.1 mm barrel connector fit my laptop's DC input jack?

The cable uses a standard 5.5 mm outer and 2.1 mm inner diameter barrel, matching most laptop power ports with that size.

How do I connect the female-to-male extension without reversing polarity?

Align the centre pin of the male plug with the female socket and push straight in; the keyed barrel prevents incorrect orientation.

When should I replace the 22 AWG TPE cable?

Replace it if the jacket shows cuts, the connectors become loose, or the cable feels stiff from repeated bending.
