StarTech USB2CUB50CM USB-C to Micro-B Charge and Sync Cable

Overview

The StarTech USB2CUB50CM is a 50cm (1.6 ft) USB-C to Micro-B cable built for connecting USB-C host systems to USB 2.0 Micro-B devices — think external hard drives, barcode scanners, industrial handhelds, or legacy peripherals that still rely on the Micro-B connector. At 480 Mbit/s, it delivers the full USB 2.0 High Speed data rate for reliable charge-and-sync duty in tight cable runs where a full-length cable would create unnecessary clutter. If you're sourcing cables for StarTech connectivity solutions or outfitting a mixed-connector device fleet, this is a workhorse short-run solution worth having on hand.

Key Features

• 480 Mbit/s USB 2.0 High Speed: Transfers a 1GB file in roughly 17 seconds under ideal conditions — fast enough for firmware pushes, data offloads, and routine sync tasks without the overhead of USB 3.x wiring requirements.
• USB-C to Micro-B pinout: Bridges modern USB-C host ports (laptops, docking stations, single-board computers) directly to legacy Micro-B devices, eliminating the need for a separate adapter in the chain and reducing potential signal-loss points.
• Aluminum-Mylar foil + braid shielding: The dual-layer shield suppresses EMI from nearby power supplies, motors, and RF sources — relevant when this cable lives inside a rack, near a UPS, or alongside PoE cabling in a network closet.
• 22/30 AWG wire gauge: 22 AWG power conductors support adequate current delivery for device charging; 30 AWG data conductors keep the cable flexible and easy to route in confined spaces. This gauge selection is deliberate — heavier power wires, lighter signal wires.
• Nickel-plated connectors: Nickel plating resists corrosion and provides consistent contact resistance over thousands of insertion cycles — useful in environments where cables get unplugged and replugged frequently.
• PVC jacket, 50cm form factor: The 0.5m length (19.7 in) is intentional for short-reach connections — desktop peripherals, rack-mounted devices, or panel-mounted handhelds where a 1m or 2m cable would loop and snag. The PVC jacket handles routine flex without cracking.
• Lifetime warranty: StarTech backs this cable with a lifetime manufacturer warranty, removing it from the replacement-cycle conversation for standard office and light-industrial use.

Integration and Compatibility

The USB2CUB50CM works with any USB-C host port operating at USB 2.0 speeds and any device with a standard USB Micro-B receptacle. This covers a wide range of USB cables and connectivity accessories scenarios: Android devices, portable barcode scanners, small NAS units, USB-powered sensors, and legacy cameras or printers that predate USB-C adoption. Note that this cable does not support USB 3.x speeds or USB Power Delivery beyond what the Micro-B connector specification allows — if your device needs fast charging via USB-PD or SuperSpeed 5/10 Gbps data, you need a different cable entirely. For deployments that also require broader connectivity planning, confirm the host port's USB version before assuming compatibility.

Frequently Asked Questions

Q: What is the data transfer speed of the USB2CUB50CM?

A: The USB2CUB50CM supports USB 2.0 High Speed at 480 Mbit/s maximum — sufficient for sync, firmware updates, and charging, but not USB 3.x SuperSpeed transfers.

Q: Will this cable charge my Micro-B device?

A: Yes. The 22 AWG power conductors support charging through a USB-C host port, subject to the host's output current and the device's charge acceptance. It does not support USB Power Delivery negotiation.

Q: How long is the USB2CUB50CM?

A: The cable measures 50cm (0.5m / 1.6 ft / 19.7 in) — designed for short-reach connections where cable management is a priority.

Q: What shielding does the USB2CUB50CM use?

A: It uses an aluminum-Mylar foil layer combined with a braid shield — dual-layer construction that reduces EMI interference from nearby power and network cabling.

Q: What warranty does this cable carry?

A: StarTech provides a lifetime manufacturer warranty on the USB2CUB50CM.

Eden Phillips

The detail I keep coming back to on the USB2CUB50CM is the 22/30 AWG split construction — 22 AWG on the power conductors, 30 AWG on the data lines. That's not an accident; it means you get adequate current delivery for device charging without the cable becoming stiff and unmanageable at 50cm. For rack-mounted or panel-mounted deployments where cables need to flex without fatiguing the connector, that combination matters more than the spec sheet makes obvious.

Technical Highlights:

• Dual-layer shielding (foil + braid): In environments with dense PoE cabling or nearby switching power supplies, the aluminum-Mylar foil stops high-frequency EMI while the braid handles lower-frequency noise — both layers together give you cleaner signal than foil-only designs common in cheaper cables.
• 480 Mbit/s at 50cm: USB 2.0 signal integrity degrades with length; at 0.5m you're well within spec with headroom to spare, so you're not trading signal quality for the short run — you get the full rated throughput reliably.
• Nickel-plated connectors: In high-insertion-cycle environments (device docking stations, handheld scanners returned to charging cradles repeatedly), nickel plating maintains consistent contact resistance far longer than bare copper or tin-plated alternatives.

Deployment Considerations:

• Confirm your Micro-B device accepts USB 2.0 speeds — if the peripheral requires USB 3.x (SuperSpeed) data rates, this cable will not satisfy that requirement regardless of the host port capability.
• At 17g and 50cm, this cable is sized for short-reach fixed connections, not repeated hot-swapping between distant ports. Route it once and leave it; the PVC jacket will outlast frequent repositioning better than it handles repeated coiling and uncoiling.

This cable fits cleanest in fixed short-run installations: a USB-C laptop or dock port to a panel-mounted barcode scanner, a rack unit's management port to a local USB drive, or a charging station where Micro-B devices dock at a fixed position and cable length is a real constraint.
