Purpose and fit

This four-pack of short DC adapter cables converts a 5.5 mm × 2.1 mm female barrel jack to a 4.0 mm × 1.7 mm male plug. Each 15 cm lead is rated for 12 V and up to 3 A, making it suitable for powering routers, speakers, fans or desk lamps that use the smaller DC 4017 port.

Sustained-load behaviour

The 22 AWG pure copper conductors keep resistance low so the cable can deliver the full 3 A continuously without noticeable voltage drop. The PVC jacket and moulded strain relief protect the cores from heat and repeated flexing during permanent installations.

Build and daily use

Weighing only 10 g per cable, the set adds negligible bulk to a backpack or equipment bag. The compact moulded connectors fit tightly into crowded power strips or device ports, and the black finish blends discreetly with most consumer electronics.

Questions about this item

Does the 22 AWG cable run warm when a 12 V device draws the full 3 A for hours?

The 22 AWG pure copper conductors keep resistance low, so the cord stays cool even at the rated 3 A continuous load.

My router has a 5.5 mm × 2.1 mm jack — will this plug straight in without any extra adapters?

Yes, the DC 5521 female end matches your router's jack exactly, and the DC 4017 male end fits the power supply.

Can I chain one of these 15 cm cords after an older 5.5 mm × 2.1 mm extension cable without voltage drop issues?

The short 15 cm length and 22 AWG wire add negligible resistance, so chaining works fine for 12 V gear.
