Its durable metal casing and 360° rotating design ensure both reliability and convenience.

2. Setup and Installation
The SSK USB Flash Drive is designed for plug-and-play functionality, requiring no additional software or application installation.
2.1 Device Compatibility
This flash drive is compatible with a wide range of devices, including:
- Computers (PC, Mac)
- Laptops
- Smartphones (OTG-enabled Android Type-C phones)
- Tablets
- Car Audio Systems
- Smart TVs
Important Note: This device does NOT support Micro-USB or Lightning connections.


2.2 Connecting the Drive
- Identify the appropriate port on your device (USB-A or USB-C).
- Rotate the flash drive to expose the desired connector.
- Insert the connector firmly into the device's port. The drive should be recognized automatically.
3. Operating Instructions
3.1 Data Transfer
Once connected, the flash drive will appear as an external storage device on your computer or mobile device. You can then drag and drop files to and from the drive for file sharing, data transmission, and video playback.

3.2 360° Rotating Design
The flash drive features an innovative 360° rotating design with a 90° stuck point. This allows you to easily switch between the USB-A and USB-C connectors while protecting the unused connector. The design also prevents accidental rotation during use.

4. Maintenance
To ensure the longevity and optimal performance of your SSK USB Flash Drive, follow these maintenance guidelines:
- **Physical Protection**: The casing is made of premium zinc alloy, providing excellent shockproof performance. However, avoid dropping the device from significant heights or subjecting it to excessive force.
- **Heat Dissipation**: The metal casing aids in fast heat dissipation. Ensure the drive is not covered or placed in confined spaces during prolonged use.
- **Preventing Loss**: Utilize the integrated lanyard buckle design to attach the flash drive to a keychain or lanyard, reducing the risk of misplacement.
- **Environmental Conditions**: Keep the drive dry and avoid exposure to extreme temperatures or corrosive substances.

5. Troubleshooting
5.1 Capacity Discrepancy
You may notice a difference between the advertised capacity and the capacity displayed on your computer. This is normal due to different calculation methods:
- **Computer Calculation**: 1 Gigabyte (GB) = 1024 Megabytes (MB)
- **Flash Drive Manufacturer Calculation**: 1 Gigabyte (GB) = 1000 Megabytes (MB)
Therefore, the displayed capacity on your computer will be approximately 90% of the actual identification (e.g., a 32GB drive may show approximately 29GB).
5.2 Transfer Speed Variations
The stated read speed of up to 150MB/s is for USB 3.1/3.2 connections. Write speeds are typically lower and can vary significantly based on several factors:
- **Capacity**: Larger capacity drives generally offer faster speeds.
- **USB Port Type**: Connecting to a USB 2.0 port will result in significantly slower speeds compared to USB 3.0/3.1/3.2 ports.
- **File Type and Size**: Transferring many small files is often slower than transferring a few large files.
- **System Performance**: The performance of your computer or mobile device can impact transfer speeds.

5.3 Device Not Recognized
- Ensure the flash drive is fully inserted into the USB port.
- Try a different USB port on your device.
- Verify that your device's port is functional.
- Confirm your device supports USB-C or USB-A connections and is OTG-enabled for mobile devices.
