Supporting data transfer speeds up to 5Gbps, it allows you to connect multiple USB peripherals such as external hard drives, flash drives, keyboards, mice, printers, and card readers to compatible USB-C laptops, tablets, and other devices.

It also includes an auxiliary power input to improve stability when connecting higher-power USB devices such as external hard drives.

USB-C to 4x USB-A Expansion

The CM219 expands one USB-C connection into four full-size USB-A ports.

The four USB-A ports support high-speed USB data transfer.

• USB 3.0 / USB 3.2 Gen 1: Up to 5Gbps
• USB 2.0: Up to 480Mbps
• USB 1.1: Backward compatible

The 5Gbps specification makes the CM219 suitable for transferring files between compatible USB storage devices and computers.

Actual performance depends on the host device, connected storage, and simultaneous activity across the hub.

The CM219 can connect multiple peripherals simultaneously, including:

• External SSDs

The four ports share the bandwidth and available power of the hub.

Auxiliary Power Input

The CM219 includes a separate power connection intended to provide additional power to the hub when using demanding peripherals.

This is particularly useful with:

• External HDDs
• Multiple USB storage devices
• Other higher-power USB peripherals

This auxiliary input does not turn the CM219 into a laptop Power Delivery charger. It is intended to provide additional power to connected USB peripherals/hub operation.
