In the ever-evolving world of electronics, the USB-C standard has become a cornerstone for charging, data transfer, and video output across devices like laptops, tablets, and smartphones. The USB-C Extension Cable 1ft USB-C 3.1 Male to USB-C Female Extension Cable from Pacific Custom Engineering offers a practical solution for extending these connections. Let’s explore the features, applications, and considerations of this compact 1-foot cable to help you determine its place in your setup.

What Is the USB-C Extension Cable?
This USB-C extension cable, measuring 1 foot (0.3 meters), features a USB-C 3.1 Gen 2 male connector on one end and a USB-C female connector on the other. Designed to extend an existing USB-C connection, it supports data transfer speeds up to 10Gbps, 100W charging (20V/5A), and 4K video sync at 60Hz when paired with compatible devices and displays. The cable is constructed with a nylon-braided exterior and gold-plated connectors, incorporating a reinforced strain relief design to withstand repeated bending and plugging. Its symmetrical USB-C design ensures it plugs in correctly every time, reducing wear on device ports.
Key Features and Specifications
- Length: 1 foot (0.3 meters) – A short length to minimize signal degradation.
- Data Transfer: Supports up to 10Gbps, enabling rapid file transfers for USB 3.1 Gen 2 devices.
- Charging Capacity: Handles up to 100W (20V/5A) power delivery, suitable for fast charging with compatible chargers.
- Video Support: Transmits 4K video at 60Hz via DisplayPort Alt Mode, ideal for connecting to monitors or hubs.
- Construction: Nylon-braided jacket with gold-plated connectors and reinforced strain relief for durability.
- Compatibility: Works with USB-C 3.1 Gen 2 devices, including laptops, tablets, and smartphones, though performance depends on the connected hardware.
Pacific Custom Engineering provides this cable as a genuine component, ensuring reliable performance for a range of connectivity needs.
Practical Applications
This 1-foot USB-C extension cable serves several useful purposes, making it a versatile addition to your electronic toolkit:
- Port Extension: Extends USB-C ports on devices like MacBooks or iPads, improving access for hubs or peripherals in tight spaces.
- Charging: Facilitates fast charging for USB-C devices when used with a 100W-capable charger and cable, ideal for workstations or travel.
- Data Syncing: Transfers large files or connects peripherals at speeds up to 10Gbps, beneficial for data-heavy tasks.
- Video Output: Connects USB-C devices to 4K monitors or TVs for streaming or presentations, leveraging DisplayPort Alt Mode.
- Device Protection: Reduces wear on device ports by minimizing direct plugging and unplugging, extending the lifespan of your equipment.
Its compact size is particularly handy for setups where longer cables might introduce clutter or signal issues.
Considerations and Limitations
While the cable’s specifications are impressive, it’s worth examining some common claims and practical limitations. Many manufacturers advertise USB-C extension cables as supporting high-speed data and charging, but performance can vary. The 1-foot length is a deliberate choice, as longer cables (e.g., beyond 2 feet) can lead to signal attenuation, especially for video or high-speed data transfer. Some web discussions suggest that extending multi-port hubs or docking stations with this cable might result in compatibility issues, particularly with Thunderbolt 3 or devices requiring precise voltage delivery. Testing has shown that while it supports 100W charging, the actual power delivery depends on the source and destination devices, and video stability may degrade with extended use over longer distances.
Why This Cable Makes Sense
The USB-C Extension Cable’s short 1-foot length is a strategic advantage, reducing the risk of signal loss that plagues longer extensions. The nylon-braided design and gold-plated connectors enhance durability, while the reinforced strain relief addresses the wear from frequent use—a common concern with cheaper cables. Pacific Custom Engineering’s commitment to genuine components ensures you’re getting a product built to last, aligning with the needs of engineers and hobbyists alike.
Conclusion
The USB-C Extension Cable 1ft USB-C 3.1 Male to USB-C Female Extension Cable from Pacific Custom Engineering is a reliable tool for extending USB-C connections with support for 10Gbps data, 100W charging, and 4K video. Whether you’re optimizing a workstation, protecting device ports, or enhancing video output, this cable offers a practical solution for compatible setups. However, its performance hinges on matching device capabilities and avoiding overextension, so it’s best suited for short-range, high-quality connections.
