DC Power Extension Cable 3.3ft Length

This 3-pack of 22AWG DC power extension cables measures 3.3ft each and features male-to-male connectors in 4.0mm×1.7mm and 5.5mm×2.1mm sizes. The oxygen-free copper conductors support stable power delivery for devices drawing 1A to 3A current. Black PVC jackets provide abrasion resistance for daily use.

Home Office Users With Matching DC Ports

Suitable for owners of monitors, routers, projectors or game consoles that use the exact DC connector sizes listed. Buyers whose equipment requires different barrel dimensions, higher current capacity or longer cable runs should look at other options. The fixed 3.3ft length may not reach distant outlets.

Connector Interface 4.0mm×1.7mm to 5.5mm×2.1mm

The critical specification is the male-to-male adapter connecting a 4.0mm×1.7mm plug to a 5.5mm×2.1mm jack. Verify both your device input and power supply output match these exact dimensions before ordering. No other connector variants are included in this pack.

Questions about this item

Which connector variant should I pick from the 4.0×1.7 mm, 5.5×2.1 mm or 5.5×2.5 mm options?

Match the cable to your device's power port: use 4.0×1.7 mm for ports marked DC4017, 5.5×2.1 mm for DC5521, and 5.5×2.5 mm for DC5525.

What does the 22 AWG rating mean for actual power delivery?

22 AWG conductors support stable operation for low-voltage DC devices drawing between 1 A and 3 A.

How does the DC 5.5×2.1 mm interface limit usable length?

The cable is offered in 1.0 ft, 1.6 ft, 3.3 ft, 6.6 ft and 9.8 ft lengths; choose the shortest that reaches to minimise voltage drop.
