  • Adapter typePower Adapter
  • Extends laptop power reach with one-metre cable
  • Flexible TPE jacket resists everyday wear
  • 22AWG conductors deliver steady current to device
  • 5 x 2.1 mm plug fits common laptop barrels
  • Female-to-male design connects directly to existing adapter

Cable Purpose & User

This extension cable adds approximately one metre of reach to a 5.5 by 2.1 millimetre DC barrel connection. It suits laptop owners who need extra length between their power brick and the wall outlet or device port. The 22 AWG conductors and TPE jacket provide flexible routing for everyday indoor use.

Not Suitable For

Buyers who require a different barrel diameter or pin size cannot use this cable. It also does not serve situations that demand a right-angle plug, locking connector or higher current capacity than 22 AWG allows. Users needing outdoor-rated or shielded cable should look elsewhere.

Deciding Specification

The 5.5 by 2.1 millimetre barrel interface is the single detail that determines compatibility with your power supply and device. Verify that both the adapter tip and the equipment jack match this exact dimension before purchasing.

Questions about this item

Should I choose the 5.5 x 2.1 mm version or a different barrel size for my laptop?

Select this cable only if your laptop power jack and the original supply both use a 5.5 mm outer diameter with a 2.1 mm centre pin; other barrel sizes will not mate correctly.

What does the 22 AWG rating mean once the cable is plugged in?

The 22 AWG copper conductors keep resistance low over the one-metre length, so voltage drop stays small and the laptop receives stable power.

Does the 5.5 x 2.1 mm interface limit the wattage I can draw?

The barrel connector itself is commonly rated for several amperes, so it will handle typical laptop supplies without becoming a bottleneck.
