Two-pack USB-A to DC power cables

This 2-pack supplies two 28cm cables that convert a USB 2.0 A port into a 5V DC barrel jack for small devices. Each cable carries power only and cannot transfer data. The fixed length keeps desktop or rack wiring tidy. Buyers who need longer reach or a single cable should look elsewhere.

Limited by USB 2.0 power delivery

The USB 2.0 interface restricts output to the standard 5V supply available from the host port. No voltage conversion or regulation is built into the cable itself. Devices requiring higher voltage, higher current or data communication will not work with this adapter.

Exact 3.5mm x 1.35mm barrel plug

The DC connector has a 3.5mm outer diameter and 1.35mm inner diameter, so it only fits devices with that precise jack size. Confirm the device port matches these dimensions before purchase to avoid mismatch and potential damage.

Questions about this item

Should I take the 28cm or a longer cable?

The pack contains two 28cm cables; choose this length when the USB port and the DC socket sit close together, otherwise measure the gap and select a longer lead.

What does the 5V output mean when I plug it into a laptop USB port?

The cable simply passes the port’s 5V supply through the 3.5×1.35mm barrel plug, so the connected device receives the same 5V the USB port delivers.

Does the USB 2.0 connector limit the power my device can draw?

The USB 2.0 Type-A plug follows the standard 5V specification; actual current is governed by the host port and the device, not by the cable itself.
