USB 3.0 (Host) to USBC (Device) Adapter Key benefits Enables direct USB data connection from a USB 3.0 host (PC, laptop, or other host) to a USBC device for fast data transfer up to 5 Gbps. Oneway design prevents incorrect connections — clearly labeled input (host) and output (device) to avoid damaging devices or creating connection errors. Supports an external DC 5V 3A power source to supply the connected USBC device while transferring data (useful for higherpower peripherals that need added power). What this adapter does Function: Converts a USB 3.0 host port to a USBC device connection for data transfer only. Performance: USB 3.0 data throughput up to 5 Gbps. Power: Accepts external DC 5V 3A input to power the connected USBC device when needed. Compatibility and important limitations Check the printed labels on the adapter before use: the side marked 'input' must connect to the host (e.g., your computer) and the side marked 'output' must connect to the USBC device. The connection is not reversible. This adapter does NOT support video, audio, USB Power Delivery (PD) negotiation, or docking station functions. It only transfers USB data (max 5 Gbps); do not expect alternate modes (DisplayPort, HDMI) or advanced PD charging features. Practical use scenarios Transfer large files between a laptop USB 3.0 port and a USBC external SSD or flash drive at USB 3.0 speeds. Connect a USBC accessory (storage, USB peripherals) to a desktop computer's USB 3.0 host port for dataonly use. Use with an external DC 5V 3A power source when a USBC device requires additional power while performing data transfers (note: PD negotiation and docking features remain unsupported). Quick usage tips Always confirm which side is marked 'input' (host) and 'output' (device) before plugging in. Do not expect video, audio, or PD charging via this adapter. For performance, use with USB 3.0capable ports and compatible USBC devices that accept standard USB data connections.
