Power cable for 5 V DC devices

The StarTech.com USB2TYPEH cable connects a standard USB-A port to a 3.4 mm Type H barrel jack, delivering 5 V DC power from a laptop or desktop. Its 3 ft length suits bench testing, mobile peripherals, and compact device charging where a dedicated wall adapter is inconvenient.

Verify barrel size and voltage

Confirm the target device requires exactly 5 V DC and uses a Type H barrel with a 3.40 mm outer diameter and 1.30 mm inner diameter. The cable supplies only what the host USB port provides, so check the port’s current limit matches the device’s draw before connecting.

Stable output within USB limits

Molded strain-relief connectors and aluminum-mylar foil with braided shielding maintain a consistent 5 V feed during extended use, provided the host port sustains its rated current. The durable PVC jacket resists wear from repeated bench or field deployment.

Questions about this item

Does the USB2TYPEH cable include a USB power adapter or only the cable itself?

The package contains the 3 ft USB-A to 3.4 mm Type H barrel cable only; a USB power source such as a laptop port or wall charger must be supplied separately.

The barrel connector is listed as 3.40 mm outer diameter and 1.30 mm inner diameter — how do I know if this matches my device?

Check the device’s power input label or manual for a 5 V DC barrel jack specified as 3.4 mm OD / 1.3 mm ID; only that exact size will fit securely.

The cable is rated for 5 V DC — what does that mean when I plug it into a standard USB-A port?

A standard USB-A port supplies 5 V, so the cable passes that voltage directly to the barrel connector, powering any 5 V DC device that draws within the port’s current limit.
