What this cable does

This DC power cord converts a 5.5mm x 2.5mm female port to a 5.5mm x 2.1mm male plug for 12V devices. It supports routers, speakers, fans and desk lamps that use a 5521 port. Each cord is 1FT long and rated for up to 3A current. The pack contains two cables for spare or multi-device use.

Thermals noise and power draw

The 22AWG pure copper conductors keep resistance low for stable current delivery at 12V. PVC jacket insulation prevents heat build-up during continuous operation. No active cooling is required and the cable runs silently. Maximum supported load is 3A within the 12V rating.

Build quality and daily use

Injection-moulded connectors and a flexible PVC jacket withstand repeated plugging and unplugging. Each cable weighs 13g and coils neatly into a backpack or laptop bag. The 5525 female to 5521 male orientation fits only equipment with matching ports. Not suitable for devices that need a 5.5mm x 2.5mm male plug or higher voltage than 12V.

Questions about this item

How do I connect the 5.5mm x 2.5mm female end to my device's 5.5mm x 2.1mm port?

Insert the cable's 5525 female connector onto the device's 5521 male jack; the 22AWG pure copper core handles up to 3A at 12V for routers, speakers or lamps.

Will the PVC jacket or 22AWG conductors degrade and need replacement?

The PVC jacket and 22AWG pure copper wires are rated for continuous 12V 3A use; no scheduled replacement is required unless physical damage occurs.

At what point does the 30cm length or 22AWG gauge limit sustained 3A delivery?

The 22AWG conductors are specified for a maximum of 3A at 12V; sustained loads at that ceiling may warm the cable, so monitor temperature during continuous high-draw operation.
