USB-stick Silicon Power 64 GB USB Type-A USB Type-C Mobile C31

The Silicon Power Mobile C31 is a compact 64 GB USB flash drive with dual interfaces: USB Type-A and reversible USB Type-C. Designed for easy data transfer between older USB-equipped PCs or laptops and newer Type-C smartphones, tablets or computers, the C31 supports USB 3.2 Gen 1 speeds while maintaining a small, durable form factor with a 360° swivel cap and COB (Chip on Board) construction. It is available in black and silver and weighs approximately 3.3 g.

Advantages

The dual USB Type-A and Type-C interfaces enable direct, cable-free transfers between legacy devices and modern Type-C devices. The reversible Type-C connector simplifies repeated connections. A 360° swivel cap protects unused connectors and eliminates loose caps, while COB technology reduces size and improves resistance to water, dust and vibration. The drive's light weight and jewellery-like diamond-cut pattern make it easy to carry and visually discreet. Lifetime warranty is provided by the manufacturer.

How to use

Choose the appropriate connector for your device (Type-A for older PCs/laptops, Type-C for modern phones, tablets or notebooks) and insert the drive firmly into the port. Use your operating system's file manager to copy, move or open files as needed. For Android Type-C devices, install or open the SP File Explorer app if provided to enable automatic file categorization and one-touch backup features. Always eject or safely remove the drive from the host device before unplugging to avoid data loss.

Recommendations

Keep the swivel cap closed when not in use to protect the connectors. Avoid exposure to liquids and extreme temperatures despite the COB protection, and back up important data in multiple locations. Use compatible USB 3.2 Gen 1 ports to achieve the drive's full transfer performance.
