Take out all items in the packing box, except Lvlian USB 3.0Share Switch In addition, two pieces of A-A transmission wire, desktop controller, manual and warranty card are attached.
Lvlian USB 3.0Share Switch The aircraft aluminum alloy fuselage design is adopted, and the surface is anodized. It is wear-resistant and durable, enhances the metal texture and is easier to dissipate heat as a whole.
Lvlian USB 3.0Share Switch The top is a black and gray two color splicing design, the middle is a switch button, and the bottom is the "UGREEN" brand words.
The top right side of the Greenlink USB 3.0 shared switch is marked with 5Gbps and the device 1/2 indicator.
The back of the shared switch is supplemented with other product parameter information inscriptions, name: USB 3.0 shared switch two in four out, model: CM662.
There is a silicone anti-skid pad around the ground of the shared switch, which can not only stabilize but also accelerate heat dissipation.
The transmission ports on the back are USB-C power supply interface, USB IN 2, USB IN 1 input interface from left to right.
The front ports are Mini USB, one USB-C and three USB-A interfaces from left to right. The four USB interfaces are all 5Gbps specifications.
The figure shows the desktop controller matched with the Lvlian USB 3.0 shared switch. The wire interface type is Mini USB.
The front of the desktop controller is equipped with a switch button and the "UGREEN" Lvlian brand LOGO.
The transmission wire is A-A type, and the sub end is also gravure printed with "UGREEN" Lvlian brand logo.
The length of desktop controller and wire is about 155cm.
The length of A to A transmission wire is about 150cm.
The length of the Lvlian USB 3.0 shared switcher is about 123.01mm.
The width of the Greenlink USB 3.0 shared switcher is about 54.28mm.
The thickness of the Lvlian USB 3.0 shared switcher is about 16.42mm.
The weight of the Lvlian USB 3.0 shared switcher is about 109.3g.
user's experience
The desktops and laptops are respectively connected to the Lvlian USB 3.0 shared switcher through two standard A to A wires. At the same time, in order to ensure its stable use, the USB-C interface on the back is also connected to an independent power supply.
If the connection effect is shown, the Lvlian USB 3.0 shared switcher not only supports the Windows series, but also is compatible with desktop operating systems such as macOS and Linux, so it can be combined at will according to needs.
Device switching
The Greenlink USB 3.0 shared switcher supports the use of the switch button on the top of the main body, or the use of a desktop controller with a wire length of 1.5 meters to switch connected terminal devices.
After pressing the switch button/desktop controller, it can be seen that the mouse and USB4 mobile hard disk box originally connected to the laptop are switched to another pre connected Windows desktop, and the switch delay is basically insensitive.
For users who need to work with multiple systems/devices at the same time, the two in and four out design of the Lvlian USB 3.0 shared switcher can connect two terminal devices at the same time. The mouse, keyboard, printer, hard disk and other peripherals can freely switch the connected terminal devices as required, making daily use and office work more efficient and convenient.
data transmission
The above experience shows the most important peripheral sharing/switching function of the Lvlian USB 3.0 sharing switch. Now let's take a look at the performance of the USB port in data transmission.
Connect to the external hard disk through the USB-A port of the Greenlink USB 3.0 shared switch. At this time, the hard disk information has been successfully read, indicating that the USB-A port supports the data reading function.
The transmission speed is tested by CrystalDiskMark. The measured reading speed can reach 457.21MB/s, and the writing speed can reach 466.15MB/s, which conforms to 5Gbps data transmission.
charge
Connect Huawei Pura 70 Pro+to the shared switcher through C-C cable, and the measured charging power on one side of the mobile phone is about 2.23W, that is, the four output interfaces can realize basic charging functions in addition to data transmission.
Summary of charging head network
The Lvlian USB 3.0 shared switcher is made of aluminum alloy metal shell, and its surface is anodized to make it more wear-resistant and heat dissipating;It is equipped with two USB-A input interfaces and four 3A1C output interfaces, and the transmission specification of each interface is 5Gbps. At the same time, there is an independent power supply Type-C interface and a separate Mini USB interface to connect the desktop controller. The connected peripheral can be switched to another computer with one key.
In terms of measured performance, after connecting the laptop, the USB-A/USB-C port can realize peripheral expansion function, data transmission function and basic charging function, and the read/write speed is also close to 460MB/s, which is consistent with the nominal, and supports the basic charging power.At the same time, it was measured that after pressing the switch button of the Greenlink USB 3.0 shared switcher, the peripherals were quickly connected to another computer, and the switch was basically insensitive.
On the whole, the Lvlian USB 3.0 shared switch is a blessing for users who need to work in multiple systems/devices at the same time.The design of "two in four out" can connect two terminal devices at the same time, no need to install drivers regardless of the system. At the same time, the mouse, keyboard, printer, hard disk and other peripherals can freely switch the connected terminal devices according to the needs, so that the office entertainment experience can be further improved.
