  • 120 cm cable gives flexible placement for routers, hubs or external drives
  • Standard USB-A plug works with chargers, power banks or PC ports
  • Precise 2.5 mm outer and 0.7 mm inner diameters match many 5 V DC inputs
  • Simple plug-and-play design needs no drivers or configuration

USB Male to DC 2.5 x 0.7mm Cable

This cable connects a standard USB-A port to devices that require a 2.5 mm outer diameter and 0.7 mm inner diameter barrel jack. It suits routers, small switches, external drives or audio gear that draw power from a USB charger or power bank. The 120 cm length gives flexible placement on a desk or behind equipment.

Thermals noise and power draw

The cable itself generates no audible noise and adds negligible thermal load because it contains no active components. Power delivery depends entirely on the USB source and the connected device, so heat and current stay within the limits of the host port and the equipment being powered.

Behaviour under sustained load

Voltage drop across the 120 cm conductor is minimal for typical low-power peripherals, so connected devices remain stable during continuous operation. The fixed 2.5 mm by 0.7 mm barrel ensures a secure fit that does not loosen over time, preventing intermittent power loss during extended use.

Questions about this item

How do I install this cable and which step is often done incorrectly?

Plug the USB male end into a power source and the DC 2.5 x 0.7mm jack into the device; the step often missed is verifying the jack's 2.5mm outside and 0.7mm inside diameters match the device port exactly.

What maintenance or replacement will this cable need over time?

Inspect the USB and DC connectors periodically for bent pins or cable fraying near the strain reliefs; replace the cable if the jacket is damaged or the connection becomes intermittent.

What limit appears first during sustained use of this 120cm cable?

Voltage drop over the 120cm length becomes the limiting factor under sustained high-current loads, potentially causing the connected device to receive less power than required.
