StarTech USB2C5C4M 13.1 ft USB-C to USB-C Cable — 100W Power Delivery

Overview

The StarTech USB2C5C4M is a 13.1 ft (4.0 m) USB-C to USB-C cable engineered for deployments where you need to charge or power USB-C devices across a longer run than a standard 1 m or 2 m cable allows. With 100W (5A) power delivery and USB-IF certification, it covers fast-charge laptops, tablets, and other USB-C peripherals from a distance — useful on workbenches, AV carts, conference tables, and equipment racks where the power source isn't immediately adjacent to the device. At 480 Mbit/s data throughput, it also handles USB 2.0 data transfer alongside charging, so you're not giving up connectivity to get the longer reach.

Key Features

• 100W / 5A Power Delivery: Delivers up to 100W — enough to fast-charge most USB-C laptops and power demanding peripherals at full speed. No need for a separate AC adapter at the device end if your charger or dock supports 100W PD output.
• 13.1 ft (4.0 m) Length: Four meters gives you practical reach across a conference table, from a floor-mounted power strip to a wall-mounted display, or between workstation and equipment shelf — without daisy-chaining two shorter cables and adding a failure point.
• 480 Mbit/s Data Rate: USB 2.0 speed handles firmware flashing, file transfers, and device syncs alongside charging. If you need USB 3.x speeds (5–20 Gbps), note this cable is rated at 480 Mbit/s — adequate for most device management tasks, but not for high-throughput storage transfers.
• USB-IF Certified: The USB Implementers Forum certification means the cable has been tested against the USB specification for electrical and mechanical compliance — it won't misreport power capability to the host charger or damage devices by negotiating incorrect voltage.
• Aluminum-Mylar Foil with Braid Shielding: The combined foil-and-braid shield reduces EMI pickup along the 4 m run — important in rack environments or near switching power supplies where an unshielded cable would introduce noise on the data lines.
• 24/26 AWG Wire Gauge: 24 AWG power conductors support the 5A current rating without excessive resistive voltage drop over the full cable length. 26 AWG signal conductors keep data integrity intact at 480 Mbit/s.
• PVC Cable Jacket: Flexible PVC jacket withstands the bend radius demands of cable management trays and desk routing without cracking — rated for 0°C to 35°C operating range, so it's suited for climate-controlled office, lab, and rack environments.
• USB Type-C Connectors Both Ends: Reversible C-to-C configuration means no wrong-end plugging. Works with any USB-C power delivery charger, hub, or dock on one end and any USB-C device on the other.
• Weight: 7.7 oz (219 g): Heavier than a 1 m cable — the extra conductor mass at this length is unavoidable for 5A capacity. Factor this into suspended cable management runs where weight load matters.
• 2-Year Warranty: StarTech backs the USB2C5C4M with a 2-year manufacturer warranty, which is above the 1-year standard common on generic cables at this length.

Integration and Compatibility

The USB2C5C4M is compatible with any USB-C Power Delivery charger or dock that outputs up to 100W — common examples include laptop docking stations, GaN wall chargers, and rackmount USB-C charging units. The cable negotiates PD at the correct voltage/current profile for the attached device, so pairing it with a 65W charger will still deliver 65W (not 100W) to the device. Data transfer operates at USB 2.0 (480 Mbit/s) — compatible with USB 3.x ports on both ends, but limited to 480 Mbit/s by the cable's signal specification. Not suitable as a Thunderbolt or USB4 cable. The USB-IF certification ensures broad interoperability without the voltage-spike risks sometimes seen with uncertified long-run cables.

Frequently Asked Questions

Q: What is the maximum power this cable supports?

A: The USB2C5C4M supports up to 100W (5A) USB-C Power Delivery. The actual charging wattage delivered depends on what the charger and device negotiate — the cable supports the full 100W ceiling.

Q: Does the USB2C5C4M support USB 3.0 or Thunderbolt speeds?

A: No. The cable is rated at 480 Mbit/s (USB 2.0 data speed). It will physically connect to USB 3.x and Thunderbolt ports but will operate at USB 2.0 data rates. It is not a Thunderbolt or USB4 cable.

Q: Is the USB2C5C4M USB-IF certified?

A: Yes. The USB2C5C4M carries USB-IF certification, confirming it meets USB specification requirements for electrical performance, power negotiation safety, and mechanical compliance.

Q: What is the warranty on the USB2C5C4M?

A: StarTech provides a 2-year manufacturer warranty on the USB2C5C4M.

Q: What operating temperature range does this cable support?

A: The USB2C5C4M is rated for 0°C to 35°C operating temperature and -10°C to 80°C storage temperature. It is designed for indoor, climate-controlled environments — not outdoor or industrial temperature extremes.

Q: Can I use this cable to transfer data and charge at the same time?

A: Yes. The cable supports simultaneous USB 2.0 data transfer (480 Mbit/s) and power delivery (up to 100W) over the same connection.

Ted Perry

The detail I keep coming back to on the USB2C5C4M is the 24 AWG power conductor spec at 4 meters. A lot of long USB-C cables cut corners by using 28 AWG throughout — which cannot sustain 5A without a resistive voltage drop that causes the charger to throttle back. StarTech sized the power conductors correctly here, which is why the full 100W PD rating is actually achievable at this length rather than nominal.

Technical Highlights:

• 100W / 5A at 4.0 m: 24 AWG power conductors maintain current capacity over the full 13.1 ft run — you won't see the charging wattage sag that plagues lighter-gauge long cables.
• Foil-plus-braid shielding: Combined aluminum-Mylar foil and braid construction provides better EMI rejection than foil-only designs — worthwhile in AV racks or near UPS units where switching noise is a factor.
• USB-IF certified: Certification verifies safe PD negotiation — the cable correctly identifies itself to the charger, preventing over-voltage events on sensitive device inputs.

Deployment Considerations:

• The 480 Mbit/s data rate ceiling is the main constraint to confirm before deploying: if you need USB 3.2 Gen 1 (5 Gbps) or higher for storage or video capture, this cable is not the right pick regardless of the PD rating.
• The 0°C–35°C operating range means this is a controlled-environment cable — conference rooms, server rooms, office AV installations. Don't route it through unheated spaces or outdoor conduit even temporarily.

For conference room AV carts and laptop charging stations where the power brick is 3–4 meters from the seating position, the USB2C5C4M handles the run cleanly without a separate power brick at the table — a practical fit for corporate AV integrators who are tired of fielding complaints about half-speed laptop charging from underpowered short cables.
