User Manual

Introduction

This manual provides comprehensive instructions for the safe and efficient use of your CEYYOR C-21 USB to Type C PD Bent-angle Fast Charge Data Cable. Please read this manual carefully before use and retain it for future reference to ensure optimal performance and longevity of your product.

Safety Guidelines

Adhering to these safety guidelines will help prevent damage to the cable, your devices, and ensure user safety:

• Do not use damaged, aged, or poorly connected data cables to avoid short circuits, electrical leakage, equipment damage, and other safety hazards.
• Avoid placing data cables in high-temperature (e.g., near fire sources, heat sinks), humid (e.g., bathrooms, outdoor rain), or corrosive environments to prevent aging of the cable insulation and oxidation of the connector.
• If the data cable or connector exhibits abnormal heating, odor, or smoke during charging, immediately disconnect the power, stop using the cable, and contact after-sales service.
• Do not disassemble or modify the data cable arbitrarily to avoid damaging the internal circuit structure and affecting safety.
• Children must use the cable under adult supervision to prevent accidental biting or pulling of the data cable, thus avoiding the risk of electric shock or suffocation.
• When plugging or unplugging the data cable, hold the connector and operate steadily. Do not pull on the cable itself to avoid breakage at the connection point.
• Do not place the data cable with sharp objects (e.g., scissors, keys) to prevent scratches.

Setup

Connecting for Charging

1. First, ensure the data cable connector is undamaged and free of stains.
2. Verify that the power adapter meets safety standards and matches the data cable's rated parameters.
3. Insert the USB-A/USB-C male end of the data cable into the corresponding port on the power adapter.
4. Then, insert the other end of the data cable (Type-C) into the charging port of the device being charged.
5. Once the power adapter is connected, the device will display a charging indicator, indicating a successful connection.

Operating Instructions

Charging

This cable supports fast charging. For fast charging functionality, ensure both your phone and charger support fast charging protocols. The integrated smart chip charging design helps protect your device from overcurrent and overheating.

Data Transfer

1. Ensure both the computer and the device to be transferred are powered on.
2. Verify that the device interface is compatible with the data cable.
3. Insert one end of the data cable into the computer's USB port (USB 3.0 or later is recommended to ensure faster transfer speed).
4. Insert the other end into the device's port.
5. The computer will automatically recognize the device (for some devices, you may need to click "Trust" and "Allow" in the pop-up permission window).
6. Open the computer's file manager, locate the connected device icon, and perform file transfer operations such as copying, pasting, and deleting.
7. After the transfer is complete, it is recommended to disconnect the device using the computer's "Safely Eject Device" function before unplugging the data cable to avoid data loss.

Maintenance and Care

• After daily use, the data cable can be coiled up and stored (avoid excessive coiling or folding) in a dry storage box to prevent dust accumulation.
• If the interface becomes dusty or oily, gently wipe it with a dry, soft cloth (such as an eyeglass cleaning cloth). Do not use a damp cloth, alcohol, or other liquids to clean it, as this may corrode the metal contacts.
• When not in use for extended periods, completely disconnect the data cable and store it in a cool, dry place, avoiding direct sunlight.
• Avoid prolonged stretching or bending of the data cable. For example, do not allow the device to suspend the data cable while charging to reduce wear and tear on the interface and cable.
• When using a charger, prioritize original chargers or chargers that comply with national 3C certification to avoid data cable damage or device malfunction due to incompatible charger parameters.

Troubleshooting

• Device not charging/fast charging:
  • Ensure both the phone and charger support fast charging protocols.
  • Check if the cable connectors are clean and undamaged.
  • Verify the power adapter meets the cable's rated parameters.
• Data transfer issues:
  • Ensure both devices are powered on and recognized by the computer.
  • Try a different USB port on the computer, preferably USB 3.0 or later for optimal speed.
  • Ensure the device is properly "Safely Ejected" from the computer before disconnecting the cable.
• Cable damage/wear:
  • Avoid exposing the cable to sharp objects, excessive bending, or pulling on the cable itself.
  • The double elbow design and braided material are engineered for durability against common wear and tear.

Specifications

User Tips

• The 90-degree bent-angle design is particularly useful for comfortable device usage (e.g., gaming, watching videos) while charging, as it prevents the cable from obstructing your grip.
• The durable braided material and reinforced aluminum alloy elbow joints are designed to withstand frequent bending and reduce the risk of fracture, making this cable ideal for travel and daily use.
