Baseus USB C Hub with HDMI, Ethernet And Power Delivery

Thursday, October 03, 2019

Anyone spending thousands on a shiny, usb-c laptop with only two usb-c ports will most likely be second-guessing their purchase because without usb-a ports and hdmi ports, you won't be able to charge a non-usb-c smartphone nor connect the laptop to a tv.
Fortunately, you don't have to settle for expensive adapters from the laptop manufacturer nor put up with the inconvenience of lack of usable ports because the after market is flooded with many third-party usb-c hubs that are far superior to the dongles you can buy from the laptop manufacturer.
One of those quality usb-c adapters out on the market, it's the Baseus usb-c hub model UCN3275, which has a low-profile design with all the ports new usb-c laptops should really come equipped with. The Baseus usb-c hub has a glossy tempered glass display mounted on an aluminium alloy frame. The glass display adds a quality touch to the hub although there is no much functionality other than a small built-in led that lights on the display to indicate operation.
The rest of the Baseus usb-c hub is made with hard plastic (connector plug) and rubberized hard plastic (cable), giving a total weight of 90 grams. The dimensions are 12 cm long, 5cm wide and 2cm thick.
The rubber strips on the bottom of the Baseus usb-c hub seem to be made of TPU rubber material and are designed to prevent the hub from sliding on a surface.
The 4-inch cable has a right-angle plug and a usb-c connector with a class 3.0 specification, meaning the usb-c connector is able to pass-through both digital and analog audio signals. The Baseus usb-c adapter features every connectivity solution you will probably need, including Ethernet port, usb-a ports and a hdmi port.
The usb-a ports feature usb 3.0 standard and there are three of them. When using a single usb 3.0 port you can expect up to 5 gigabits per second transfer speeds, which is much faster than the 400 megabits per second speed you get from a usb 2.0 port. While usb 3.0 speeds are great, each usb 3.0 port on the hub won't be operating at the full usb 3.0 speed at the same time. This means, if you have multiple devices connected to each of the three usb 3.0 ports, they will all have to share a total of 5 gigabits per second between them because of the bandwidth bottleneck caused by the connection to the computer. While usb 3.0 is capable of 5 gigabits per second, the highest speed you realistically get is lower (around 3-4 gigabits per second)

When buying a usb hub adapter, you also have to keep in mind what devices you are going to be using because power hungry devices (i.e. midi controllers, hdds, ssds, etc) require more power. If that is the case, you will need a mains-powered hub that draws power from an electrical outlet via a wall power adapter. Many usb-c hub adapters are bus-powered, meaning they draw power from the usb port of the computer they are connected to. Bus power is just enough power to power a usb mouse and other low power devices like a usb keyboard, which take very little bandwidth (up to 2 megabit per second).

The Baseus usb-c hub is both bus-powered and mains-powered via the usb c power delivery port located on the backside of the hub, which can act as a power supply port to boost the power of the hub and to charge the laptop the hub is connected to. With a powered usb hub, each port gets the power it needs; hence you can use all the ports on the Baseus hub at the same time without power issues.
The integration of usb c pd, basically, makes the Baseus hub both a computer-powered and mains-powered usb hub. The usb c power delivery (PD) port can supply a maximum 20 voltage and 3 amps for up to 60W power delivery to charge a laptop, which is superb although bear in mind that you will need to use a 60W usb c charger and one is not included.
If you plan to plug in midi instruments, the Baseus hub may work okay but you probably have to look into getting a powered multi-TT (Transaction Translator) usb hub because these type of hubs are able to deliver the higher bandwidth (around 12 megabit per second) needed to transmits musical instrument data.
USB 3.0 ports are backwards compatible so, you can plug in usb 2.0 devices but you won't get usb 3.0 speeds as the usb 3.0 ports will behave as usb 2.0 ports. The usb 3.0 ports on the Baseus hub also support power draw of 5V/1.5A, which is a higher power draw than you currently get from a usb 2.0 port (5V/0.5A) and usb 3.0 port (5V/0.9A) of a computer. The Baseus hdmi port supports synchronous 4K x 2K resolution so, you can stream 4k videos in 3840 x 2160 resolution at 30fps, as well as 2k videos and 1080p videos. The Baseus hdmi port does not support true 4k (4096 x 2160 resolution) at 60 fps.
There is also an RJ45 port integrated in the Baseus hub, which is always useful to have when you need a wired Internet connection. The RJ45 port on the hub supports 10M/100M/1000M, which means the port can handle up to 1000 megabits per second (1 gigabit per second) network transfer speeds. Some hubs' RJ45 ports only support 10M/100M so, with the Baseus hub you get 10x faster network speed. There is no card reader support.
As far as compatibility, the Baseus usb c hub will work with any usb-c laptop/tablet that has a usb-c input connection such as the Apple MacBook Air, Dell XPS 13, MacBook Pro, Lenovo Yoga 730, Microsoft Surface Go and Microsoft Surface Book 2. There is 18 months warranty included, as well as a 45-day money back guarantee.
