Anyone who spends thousands of dollars on a shiny usb-c laptop with only two usb-c ports is likely to buy it in speculation, because without usb-a port and hdmi port, you will not be able to be a non-usb -c smart phone, also do not connect the laptop to the TV.


Fortunately, you don’t have to buy expensive adapters from laptop manufacturers, nor do you have to endure the inconvenience of missing available ports, because the aftermarket is flooded with many third-party USB-C hubs that are better than your dongle Buy it from the computer manufacturer.


One of the high-quality usb-c adapters on the market is the Baseus usb-c hub model UCN3275, which has a low-key design and is equipped with all the usb-c laptop ports that should really be equipped. The Baseus usb-c hub has a smooth tempered glass display mounted on an aluminum alloy frame. The glass display adds a high-quality touch to the wheel, although there is no other function except the built-in small LED indicator lights on the display to indicate operation.


The rest of the Baseus usb-c hub is made of hard plastic (connector plug) and rubber-coated hard plastic (cable), with a total weight of 90 grams. The dimensions are 12 cm long, 5 cm wide and 2 cm thick.


The rubber strip at the bottom of the Baseus usb-c hub seems to be made of TPU rubber material, designed to prevent the hub from sliding on the surface.


The 4-inch cable has a right-angle plug and a USB 3.0 connector with Class 3.0 specifications, which means that the USB-C connector can carry digital and analog audio signals.  The Baseus usb-c adapter has every connection solution you may need, including an Ethernet port, usb-a port and hdmi port.


The usb-a port has the usb 3.0 standard, of which there are three.  When using a single USB 3.0 port, you can expect a transfer speed of up to 5 gigabits per second, which is much faster than the transfer speed of 400 megabits per second obtained from the USB 2.0 port.  Although USB 3.0 speeds are great, each USB 3.0 port on the hub will not run at full USB 3.0 speeds at the same time.  This means that if you have multiple devices connected to each of the three USB 3.0 ports, the bandwidth bottleneck due to the connection to the computer must share a total of 5 Gigabits of data per second between them.  Although USB 3.0 can transmit 5 gigabits per second, the actual maximum speed you get is lower (about 3-4 gigabits per second)


When buying a USB hub adapter, you must also remember which devices to use, because power-consuming devices (such as Midi controllers, HDDS, SSD, etc.) require more power.  In this case, you will need a hub powered by a power source that will draw power from a power outlet through a wall power adapter.  Many usb-c hub adapters are bus-powered, which means they will draw power from the usb port of the computer to which they are connected.  Bus power is only enough to power USB mice and other low-power devices (such as USB keyboards), and they take up very little bandwidth (up to 2 megabits per second).

The Baseus usb-c hub is powered by the bus and from the mains through the usb c power port on the back of the hub. This port can be used as a power port to enhance the power of the hub and charge the laptop. The hub is connected.  With the help of an active USB hub, each port can get the required power.  Therefore, you can use all ports on the Baseus hub at the same time without power problems. Basically, the integration of usb c pd enables the Baseus hub to be powered either by the computer or the mains.  The usb c power transmission (PD) port can provide up to 20 volts and 3 amps of current to provide up to 60W of power to charge the laptop, which is excellent, but remember that you will need to use 60W usb c for charging Device, one of which is not included.


If you plan to plug in a Midi instrument, the Baseus hub may work properly, but you may have to consider purchasing a powerful Multi-TT (transaction converter) USB hub, because these types of hubs can provide higher bandwidth (about 12 megabits) ) Seconds) Transmit instrument data. The USB 3.0 port is backward compatible, so you can plug in a USB 2.0 device, but you won't get USB 3.0 speed, because the USB 3.0 port will be like a USB 2.0 port.  The USB 3.0 port on the Baseus hub also supports 5V/1.5A power consumption, which is higher than the power consumption you currently get from the USB 2.0 port (5V/0.5A) and USB 3.0 port (5V/0.9A).  a computer.

The Baseus hdmi port supports simultaneous 4K x 2K resolution, so you can transfer 4k video at 30fps with 3840 x 2160 resolution, as well as 2k video and 1080p video.  The Baseus HDMI port does not support true 4k (4096 x 2160 resolution) at 60 fps.


A RJ45 port is also integrated in the Baseus hub, which is always useful when you need a wired Internet connection.  The RJ45 port on the hub supports 10M/100M/1000M, which means the port can handle 1000 megabits per second (1 gigabit per second) network transmission speed.  The RJ45 port of some hubs only supports 10M/100M, so with a Baseus hub, you can get 10 times the network speed.  No card reader support.


In terms of compatibility, the Baseus usb c hub can be used with any usb-c laptop/tablet with usb-c input connection, such as Apple MacBook Air, Dell XPS 13, MacBook Pro, Lenovo Yoga 730, Microsoft Surface Go And Microsoft Surface Book2.  This includes an 18-month warranty and a 45-day money-back guarantee.
