Bring USB Power to Your Everyday DC Devices

Keep your compatible small-device setup simple with a USB to DC power cable. Connect the USB-A end to a suitable 5V USB power source and the selected barrel plug to your matching device for a straightforward power connection. The slim black cable fits naturally into a desk setup, electronics kit or everyday cable pouch without the bulk of a separate mains adapter.

Key Benefits

• USB-A to DC connection — Brings power from a suitable USB port to a compatible 5V barrel-input device.
• Six barrel-plug choices — Lets you select the connector dimensions your device requires instead of buying a multi-tip assortment.
• Option-specific cable lengths — Provides approximately 50, 70 or 80 cm of reach, depending on the selected connector.
• Simple plug-in format — Makes it easy to connect a matching device without assembling a cable.
• Understated black finish — Keeps the power lead visually unobtrusive beside your everyday electronics.

For a compatible 5V accessory at your desk or a small electronics project, the right lead keeps the connection direct and organized. Choose the barrel size for your device and use a USB supply with sufficient current capacity for the connected equipment. This cable carries USB power; it does not convert a 5V source into a higher-voltage supply.

Connector Sizes and Cable Lengths

• 2.0 × 0.6 mm: approximately 50 cm.
• 2.5 × 0.7 mm: approximately 70 cm.
• 3.5 × 1.35 mm: approximately 50 cm.
• 4.0 × 1.7 mm: approximately 80 cm.
• 5.5 × 2.1 mm: approximately 80 cm.
• 5.5 × 2.5 mm: approximately 80 cm.

Includes one USB-to-DC cable in your selected connector size. Each option is a separate cable, not a set of six interchangeable tips. Use only with a device that matches the 5V supply, barrel dimensions and connector polarity.

Frequently Asked Questions

What does this USB to DC power cable do?

It connects a suitable 5V USB power source to a compatible device with a matching DC barrel input.

Does it increase USB voltage to 9V or 12V?

No. It is a 5V power lead, not a voltage-boosting converter.

Which barrel-plug sizes are available?

Choose 2.0 × 0.6 mm, 2.5 × 0.7 mm, 3.5 × 1.35 mm, 4.0 × 1.7 mm, 5.5 × 2.1 mm or 5.5 × 2.5 mm. The dimensions identify the connector option, not a color.

How long is the cable?

Length depends on the plug: approximately 50 cm for 2.0 × 0.6 mm and 3.5 × 1.35 mm, 70 cm for 2.5 × 0.7 mm, and 80 cm for the three remaining options.

Will it work with any device that has a barrel socket?

No. The device must accept 5V DC, the selected barrel dimensions and the cable's polarity. The USB source must also supply the current required by the device. This listing is for power connection, not USB data transfer.
