Alvin's Cables Locking USB-C to USB-C Power Cable Ultra-Flexible for Blackmagic Pyxis Monitor, URSA Cine EVF, USB-C 3.2 10Gbps Data Transfer Cable for Blackmagic Micro Studio 4K G2 12in
Quick take
This 12in (30cm) locking USB-C to USB-C cable from Alvin’s Cables is designed for Blackmagic monitor and EVF workflows, combining screw-lock connectors with USB-C PD power delivery and USB-C 3.2/10Gbps data transfer. It’s built to handle frequent motion and tight rig layouts thanks to a braided, ultra-flexible design. If you expect a universal USB-C cable for any device, or if you are sensitive to the durability of the locking screw hardware, double-check compatibility and your connection style.
Pros and cons
Pros
- Screw-lock USB-C ends help prevent accidental unplugging during shoots.
- Supports USB-C PD power plus USB-C 3.2/10Gbps data and control use cases.
- Braided, tangle-free, kink-resistant cable design aimed at daily rig use (claimed 25,000+ bends).
- Ultra-compact 12in/30cm length can be ideal for short monitor or EVF runs.
Cons
- Purpose-built for specific Blackmagic ecosystem setups, so it may not match every device’s port or signaling needs.
- One review raises concern about the locking screw hardware (durability risk for some users).
- Short length limits reach if your setup needs a longer cable run.
What buyers think
Buyer feedback is generally positive on build quality and connection security, with multiple comments emphasizing the value of the screw-lock mechanism for preventing accidental disconnects and for working in tight, field-ready gear layouts. Several buyers also highlight that it performs as intended for Blackmagic gear, specifically mentioning reliable data transfer and compatibility with Pyxis-related setups. At the same time, review evidence is limited, but there is at least one report of a locking screw hardware failure, which is the main caution shoppers should consider when relying on the lock for camera-side connections.
What this cable is for
This is a short locking USB-C to USB-C cable intended to connect Blackmagic monitors, EVFs, and compatible cameras for power delivery and high-speed data/control. The cable is listed as compatible with Blackmagic Pyxis 6K, Blackmagic Pyxis Monitor, Blackmagic URSA Cine 12K, and Blackmagic URSA Cine EVF, and also targets the Blackmagic Micro Studio Camera BMMSC 4K G2 workflow.
Key features that matter in real shoots
Locking connectors for vibration and movement
Both ends use a screw-lock USB-C design. For handheld or rig-mounted setups, that means the connection is designed to stay firmly seated, reducing the chance of an accidental pullout (a common pain point with standard USB-C cables).
Power delivery plus fast data/control
The cable supports USB-C PD power and is specified for USB-C 3.2 with up to 10Gbps data transfer. That combination is aimed at workflows where your monitor or EVF setup needs more than just a charge, including control and data transmission alongside power.
Braided, flexible build for tight cable management
Construction is described as ultra-flexible with a silicone inner core and a protective nylon braided outer layer. It’s marketed as tangle-free and kink-resistant, with a durability claim of 25,000+ bends without fraying. The overall goal is a cable that is easier to route around rigs and that can handle frequent bends when you’re packing and unpacking gear.
Short 12in length (30cm) with right-angle ends
At 12 inches long, it’s most useful when you need a compact run between a monitor or EVF and the camera or power source. The plugs are right-angle lock USB-C on both ends, which can help avoid clearance issues in crowded setups.
Pros and cons
When it’s a good fit
- You’re building a Blackmagic monitor/EVF setup (Pyxis and URSA Cine workflows) and want a locking connection.
- You need a cable that carries both power delivery and high-speed data/control, not just a basic charge lead.
- Your run is short, around 12 inches, and you benefit from right-angle connector geometry.
- You prefer braided, ultra-flexible cables that are easier to manage in tight rigs.
When you might want to look elsewhere
- You need a longer run than 30cm, or you’re often rearranging gear where reach is critical.
- You’re using non-Blackmagic devices where compatibility depends on more than “USB-C shape,” especially for control/data behavior.
- You are particularly concerned about the long-term durability of locking screw hardware, given the limited but notable report of screw-related failure.
Price and availability
Pricing typically varies by retailer, but this cable is positioned as an accessory-grade, purpose-built locking USB-C option. Availability can fluctuate, so it’s worth checking the live listing for the current stock situation and latest price.
Alternatives to consider
If your main priority is connection security, the alternative category is “locking USB-C cables” with screw or latch mechanisms. If your priority is flexibility and cable management, look for braided, kink-resistant designs. If you need more reach, prioritize the same locking and PD/data feature set in a longer length. If you are unsure about compatibility for control/data between your specific Blackmagic devices, verify that both ends of your accessories use a compatible USB-C standard for the same power and data workflow.
Verdict
Alvin’s Cables locking USB-C to USB-C cable is a strong match for short Blackmagic monitor and URSA Cine EVF runs where you need PD power plus fast data/control, and where accidental unplugging would be a real problem. The braided, flexible design is also a practical choice for rig setups. The main caution is buyer-fit and hardware durability risk, since limited review evidence includes a complaint about the locking screw strength. If your setup matches the listed Blackmagic ecosystem and your cable length needs are within 12 inches, it’s a compelling option to simplify secure connections.
FAQ
Is this cable only for Blackmagic cameras and monitors?
It’s purpose-built for Blackmagic Pyxis and URSA Cine monitor and EVF workflows, including power delivery and USB-C data/control needs. For other devices, compatibility depends on whether they support the same USB-C power delivery and data/control behavior, so it’s best to confirm your exact devices before buying.
What makes the “locking” USB-C connectors important?
The screw-lock design on both ends is intended to keep the connection firmly seated, which can help prevent accidental unplugging when you’re moving the camera, handling a rig, or working in tight spaces.
Does it support power delivery and data transfer?
Yes. It’s specified for USB-C PD power delivery and USB-C 3.2 up to 10Gbps data transfer, which is relevant when your monitor or EVF requires more than just charging.
How long is the cable?
The cable length is 12 inches (30cm), with right-angle connectors on both ends.
Should I be concerned about the locking screw durability?
Review evidence is limited, but there is at least one report describing a screw hardware failure. If the locking mechanism is something you will rely on every shoot, it’s worth considering that risk, handling the connector carefully, and ensuring you’re getting the correct fit for your equipment.
