Two-Pack USB 2.0 to DC Barrel Power Cable

This two-pack supplies USB 2.0 Type A male to DC 3.5x1.35mm male barrel cables for powering small electronics from standard 5V USB sources. Each cord measures 28cm (11 inches), offering a short, flexible reach for tidy desktop or enclosure layouts. The precision-moulded barrel plug maintains tight contact to prevent intermittent power loss from vibration. High-quality internal conductors ensure stable 5V delivery with minimal voltage drop.

Suits Makers, IT Techs and Home Users

Ideal for anyone needing to power tablets, electronic dog devices, access control panels or attendance machines that use a 3.5x1.35mm DC jack from a USB charger, power bank or laptop port. The plug-and-play design requires no drivers or extra converters, making it a convenient spare or replacement cord. Not suited for devices that demand higher voltages, larger barrel diameters or longer cable runs beyond the fixed 28cm length.

Fixed 28cm Length for Close-Range Power

The 28cm (11 inch) cable comfortably handles short-distance connections between a USB power source and a nearby DC-powered gadget. It runs out when the power outlet, power bank or host port sits farther from the device than the cable allows, or when the target equipment requires a different barrel size or a voltage other than 5V.

Questions about this item

What USB port must I have free to plug in the 2.0 Type A connector?

Any standard USB 2.0 Type A port on a wall charger, power bank or laptop will supply the required 5 V.

Will the 3.5×1.35 mm barrel fit the DC jack on my older tablet?

Yes, if the tablet uses a 3.5 mm outer diameter and 1.35 mm inner pin DC socket the plug will seat securely.

How can I confirm the cable is delivering steady power after connecting?

The target device should power on without flickering or resetting when the DC plug is gently moved.
