USB flash disk Silicon Power 128 GB USB Type-A USB Type-C Mobile C31

The Silicon Power Mobile C31 is a compact 128 GB USB flash drive with both USB Type-A and reversible USB Type-C connectors. It supports USB 3.2 Gen 1 for fast data transfer and a 360° swivel cap protects the unused connector without the need for a separate cover. The drive uses COB (Chip on Board) construction for a small, durable form factor that resists water, dust and vibration and is available in silver, black and grey.

Advantages

The dual-interface design lets you transfer files directly between older Type-A computers and newer Type-C devices without adapters. USB 3.2 Gen 1 provides high-speed transfers for large files, while the swivel cap design prevents loss of a separate cap and keeps connectors protected. COB assembly reduces size and improves durability; the drive is lightweight (about 3.3 g) and backed by a lifetime warranty.

How to use
