USB-C data blocker cable Unisynk 240W — protects against data transfer while allowing power delivery

The Unisynk USB-C Data Blocker Cable 240W allows safe, power-only charging of USB-C devices by blocking all data lines while supporting high-power delivery. Designed for use with laptops, phones and other USB-C equipment, it prevents unwanted data exchange when connecting to public chargers, shared charging stations or untrusted power sources. The cable features reinforced nylon braiding and PVC-free construction for improved durability and environmental safety, and a red connector head for quick identification.

Advantages

The cable provides fast charging up to 240W while disabling data transfer, reducing the risk of data theft or accidental syncing. Reinforced braided sleeving increases mechanical durability and flexibility. The PVC-free materials lower exposure to certain plastics, and the red connector head makes the cable easy to distinguish from standard charging cables.

Suitable for

• Charging laptops, phones and tablets with USB-C power delivery
• Using public chargers and charging stations without enabling data exchange
• Corporate or team environments where device data security is required
• Travel and situations with untrusted USB power sources

Key specifications

• Connector type: USB-C to USB-C
• Maximum power delivery: up to 240 W

How to use

Connect one end of the cable to your USB-C power adapter or charging station and the other end to your device. The cable will allow power delivery up to 240 W while preventing any data communication between the connected devices. Ensure both the power source and the device support the required power delivery profile for high-watt charging.

Usage recommendations

Use this cable when charging from public or untrusted USB-C power sources to protect against data transfer. Verify charger and device compatibility for high-watt charging and avoid using the cable for data transfer tasks, as data lines are intentionally disabled.
