USB A to DC 4.0×1.7 mm power cable 2-pack

This pack contains two USB A male to DC 4.0 mm outer diameter by 1.7 mm inner diameter male plug cables. Each cable is 1 metre long and uses 22 AWG pure copper conductors for stable current delivery. The black PVC jacket adds flexibility and durability. They are designed solely to supply 5 V power at up to 3 A.

Suits 5 V devices with a 4.0×1.7 mm DC jack

Ideal for powering USB lights, small fans, portable speakers, routers or similar low-power gear that accepts a 5 V input through this specific barrel connector. The 3 A current ceiling handles most modest draws. Not suitable for devices that require a different barrel size, higher voltage, data transfer or a USB-C power source.

Connector fit: DC 4.0 mm OD / 1.7 mm ID

The decisive specification is the barrel plug dimensions: 4.0 mm outer diameter and 1.7 mm inner diameter. Only equipment with a matching DC 4017 jack will connect securely. Verify your device’s power port before purchasing.

Questions about this item

Will the 4.0 mm outer and 1.7 mm inner DC plug fit the 5 V router I already use?

The cable has a DC 4.0×1.7 mm male plug designed for 5 V devices drawing up to 3 A, so it matches equipment with that exact barrel size.

How can I confirm the cable is delivering the rated 3 A after I plug it in?

Connect it to a 5 V USB-A port and measure the output with a multimeter or USB power meter; a steady 5 V reading under load shows the 22 AWG copper conductors are working.

Does the two-pack include anything besides the two 1 m black cables?

The package contains only the two USB-A male to DC 4.0×1.7 mm male power cords; no adapters, chargers or extra accessories are supplied.
