USB cable Unitek Y-C4030GBK 3 m USB 3.1 Type-A to Type-B (data and charging)

Unitek Y-C4030GBK is a 3 m USB 3.1 Type-A to Type-B cable designed to provide both data transfer and charging between host devices and peripherals. The cable supports USB 3.1 signaling to deliver higher transfer rates than USB 2.0 while offering a longer 3-metre reach for flexible desktop and workstation layouts. Construction and connector design prioritise stable signal integrity and practical handling when connecting printers, external drives, hubs and other Type-B equipped devices.

Advantages

The cable combines USB 3.1 data throughput with charging capability in a single lead, reducing the need for separate power adapters. Its 3 m length gives increased placement flexibility for devices without compromising connection quality. Robust insulation and connector shells help protect against wear and maintain reliable contacts over repeated plug cycles. The Type-A to Type-B wiring is compatible with a wide range of peripherals that use the square Type-B plug.

Suitable for

• Connecting printers and multifunction devices to desktop or laptop hosts
• Linking external hard drives and optical drives to computers
• Connecting USB hubs and docking stations to a host port
• Situations that require extended cable reach without sacrificing transfer speed

Key specifications

• Standard: USB 3.1 data signaling
• Connector A: USB Type-A (standard host)
• Connector B: USB Type-B (peripheral)
• Length: 3 metres
• Functions: data transfer and device charging
• Cable construction: shielded design for improved signal integrity

How to use

Connect the Type-A plug to an available USB port on the computer or host device and insert the Type-B plug into the peripheral’s USB Type-B receptacle. Ensure both connectors are fully seated to establish data and power lines. The host will typically detect the peripheral automatically; install any required drivers or device software if prompted. For charging, confirm the host port provides sufficient current for the target device.

Usage recommendations

Use the cable in environments free from excessive bending or strain near connector ends; route the cable to avoid tight kinks and keep it away from high-interference sources such as large inductive motors. For sustained high-speed transfers, connect directly to host ports on the computer rather than through unpowered hubs when possible.
