Verbatim Sync & Charge 240W USB-C to USB-C Charging Cable with LED Display (31849)｜USB4・40Gbps

PD 3.1 up to 240W｜USB4 40Gbps｜Real-Time LED Power Display｜4K/120Hz Video Output｜DuPont Kevlar Reinforced

Product Overview

31849 is the flagship cable in the Sync & Charge series: it supports up to 240W with PD 3.1, data transfer speeds of up to 40Gbps via USB4, and features an LED display on the cable that shows charging power in real time. Together, these three specifications mean it functions as a charging cable, data cable, and video cable all in one.

The specifications on this page are taken from Verbatim Hong Kong's official product page (SCC4-CCD240): USB-C to USB-C connectors, 120cm length, 5.1mm cable diameter, aluminum／nylon／TPE construction with built-in DuPont Kevlar fibers, data transfer speeds of up to 40Gbps, maximum output of 240W, PD 3.1 charging standard, and USB4 support.

Why 240W deserves special mention: PD 3.1 raises the USB-C power limit from 100W to 240W (48V／5A), benefiting high-performance laptops and mobile workstations. However, the charger, device, and cable must all support PD 3.1 — if any one of them does not, power delivery will fall back to a lower level. This cable is designed to ensure it does not become the bottleneck.

Six Key Highlights

PD 3.1 at 240W: What Does 48V／5A Mean?

PD 3.1 raises the power limit from 100W (20V／5A) to 240W (48V／5A). The official specifications state that this cable supports a maximum output of 240W and the PD 3.1 charging standard, while remaining backward compatible with lower PD power profiles.

In practical terms, 100W is sufficient only for typical thin-and-light laptops; high-performance laptops, mobile workstations, and some gaming laptops require more than 140W under full load. If your laptop's original power adapter is rated at 180W or 230W, using a 100W cable will only result in slower charging or battery drain while in use.

• Up to 240W with PD 3.1 (48V／5A)
• Backward compatible with 100W and lower
• Only high-performance laptops can make full use of 240W

USB4 and 40Gbps: One Cable for Both Data and Video

The official specifications state that it supports USB4, with data transfer speeds of up to 40Gbps. USB4 combines data, video, and power delivery in a single USB-C cable, eliminating the need for a separate cable for an external display.

Practical uses of 40Gbps: an external NVMe SSD can run close to the interface limit, 4K footage can be edited directly from an external drive, and high-refresh-rate monitors can be connected. This is a level of performance that 480Mbps cables simply cannot achieve.

• USB4 support, up to 40Gbps
• Data＋video＋power in one cable
• Suitable for external NVMe SSDs and 4K editing

4K/120Hz Video Output and Thunderbolt 3 Compatibility

The official product page lists USB4 support and indicates video transmission capabilities in the specifications. With 40Gbps of bandwidth, 4K/120Hz falls within the achievable range; the actual refresh rate still depends on the monitor and the source device's DP Alt Mode support.

Note that compatibility is not the same as equivalence: this cable can be used with Thunderbolt 3／4 devices, but it is a USB4 cable, not a Thunderbolt-certified cable. If your workflow requires Thunderbolt certification, such as with certain professional audio interfaces, please contact us for confirmation before placing your order.

• 4K/120Hz-class video output
• Usable with Thunderbolt 3／4 devices
• Not a Thunderbolt-certified cable

LED Display: 240W Makes Visibility Even More Important

The official description states that the LED display shows charging status and wattage in real time. For a 240W cable, this feature is more valuable than it is on a 100W cable — because the handshake conditions for 240W are more complex, and if any component fails to meet the requirements, power delivery will silently fall back to a lower level.

Practical troubleshooting: check the displayed value after connecting your laptop. A display of 240W means all three components successfully support PD 3.1; 100W means one component is still limited to PD 3.0; 65W or lower usually indicates that the charger does not provide sufficient power.

• Real-time wattage display
• Check whether PD 3.1 has successfully negotiated
• Most valuable for troubleshooting in 240W scenarios

5.1mm cable diameter, braided exterior and reinforced connectors

The official specifications list a 5.1mm cable diameter and materials including aluminum, nylon, TPE, and built-in DuPont Kevlar fibers. The exterior features a braided design with reinforced connectors. 240W requires 5A of current, and cable diameter is directly related to heat dissipation, which is why this cable is thicker than the 100W version.

Usage reminder: The cable is thick and has a large bend radius, so do not fold it forcefully when storing it. Avoid applying prolonged lateral force to the connectors. High-power cable failures are usually caused by solder joints inside the connectors rather than the cable itself.

• 5.1mm cable diameter, supporting 5A current
• Braided exterior + reinforced connectors
• Avoid forceful folding and lateral force during storage

How it compares with 31846 / 31848

Three cables in the same series: 31846 is a 100W / 480Mbps / 3.8mm everyday cable; 31848 is a 100W cable with an LED display; 31849 is a 240W / 40Gbps cable with an LED display, designed for work use.

The selection logic is simple: 100W is sufficient for charging phones and lightweight laptops; if you need to connect an external SSD, edit 4K video, or your laptop’s original power adapter exceeds 100W, you need 240W. Choosing the wrong option may result in “plugged in but not charging.”

• 100W: Phones and lightweight laptops
• 240W: High-performance laptops and external SSDs
• Choose based on your device’s original power adapter wattage
