Where to buy

Multiport USB-C 10Gbps hub AXAGON HMC-12GM2 GEN2COMBO 12in1 expands your laptop, computer or phone with eleven ports and external box for M.2 disk.

You can easily and quickly connect up to two monitors, four USB devices, a Gigabit Ethernet network, headphones, an SD card reader, and an NVMe or SATA M.2 SSD o your computer via the reversible USB-C connector. You also get the possibility to supply laptop using Power Delivery technology at the same time. The USB-C hub will provide you with a simple and compact 12in1 docking station for notebook like MacBook Air or Pro.

The USB hub offers three USB outputs with standard USB-A connectors. Two with 5Gbps speeds and a third with 10Gbps speeds for more demanding devices. It also offers a USB-C 10Gbps data connector. The hub can also handle permanent connection of two external drives simultaneously. Thanks to the fast USB 3.2 Gen 2 interface, the hub's transfer rate is up to 10Gbps.

The second USB-C connector is reserved only for powering and simultaneous charging of laptops using Power Delivery 3.0 technology with a power of up to 100W. Connect a suitable USB-C Power Delivery charger into the hub and connect the hub to a laptop that supports Power Delivery. This saves one USB-C port.

HDMI and DisplayPort outputs provide a high-quality picture. Whether used alone or simultaneously, the ports offer resolutions up to 4K/60Hz Ultra HD and support multi-channel audio transmission. High frequencies at popular gaming resolutions of 2K/144Hz or FullHD/240Hz are also supported. Thanks to HDR (high dynamic range) support, you can enjoy a significantly expanded range of colors and contrasts without restrictions. For video outputs to work properly, the laptop must have a USB-C port with DisplayPort Alternate Mode (DP Alt Mode) support or a Thunderbolt 3 port and above.

You can connect a NVMe or SATA M.2 SSD drive thanks to the built-in slot on the back. The multiport hub thus becomes an external drive. M.2 cards can be single-sided or double-sided up to a size of 22x80 mm. The external M.2 box has no capacity limitations for SSDs and supports modern functions such as TRIM, UASP and enables reading S.M.A.R.T. disk status monitoring information.

Gigabit network card extends your computer by a fast and stable network connection, adds the missing RJ-45 network connector or another network card.
Card reader supports all versions of SD and microSD cards including SDXC and microSDXC with capacity up to 2TB. Thanks to the high-speed USB interface, you can make the most of the potential of modern memory cards. The card reader enables simultaneous handling of cards in both slots and direct copying between them.

The elegant aluminum body ensures not only mechanical resistance, but also passive cooling. Active cooling is provided by a silent integrated fan, which cools both the M.2 disk and the body of the hub itself. You will also be pleased with the finely textured surface, which does not leave fingerprints. The port replicator is the ideal accessory for laptops with a lack of USB connectors, memory or video outputs. The 50 cm USB-C cable is detachable and can be replaced with a longer cable if needed.

You can use your current USB peripherals without having to purchase new ones. Thanks to the Plug and Play and Hot Plug functions, connecting the hub itself is very simple without complicated installation, and peripherals can also be easily connected and disconnected while the computer is running. The hub does not afraid of connection to phones with a USB-C connector. For example, you can connect a flash drive, keyboard, mouse, display, TV or projector to the phone.

A): If the network card is not displayed in "Device Manager", a USB port (or a PCIe slot in the event of an internal network card) may be malfunctioning.

B): Try plugging the network card into another USB port (or another PCIe slot on the PC motherboard in the event of an internal network card, or temporarily disconnect all other PCIe cards). The network card should be detected and you should be prompted to install the drivers. If the problem persists, plug the network card into the USB port (PCIe slot) of another computer to verify its functionality.

A): By initializing the disk, you can set the mode in which the hard disk will work.

B): You can use the partition with the master boot record (MBR) or the GUID partition table (GPT). For disk up to 2TB, use the MBR option, we recommend selecting GPT on a larger disk than 2TB. Subsequently, the initialized disk should be formatted.

A): If this happens, it means that the Windows operating system did not assign a drive letter to the new storage device.

B): If the drive letter is not assigned, open "Disk Management", right-click on the desired drive and manually assign the drive letter. If the drive letter can not be assigned to the disk, it is possible that the disk is formatted as "dynamic". If you want to keep disk data, connect it to the original device and make a backup of the disk. Then convert it to a normal disk, initialize it to MBR (or GPT, see other points), and then perform Low Level Format (e.g. using the Low Level Format Tool)

A): The newly purchased disk must be initialized before first use.

B): If the new disk is not initialized automatically, open "Disk Management", right-click on the desired disk and initialize it.
