Our take
ERK-USB3-310 is a desk-oriented mouse-bungee hub with three USB 3.0 ports, a microSD/TF reader and lighting. Its fast-charging wording has no stated rate or power source.
A desktop user wanting a mouse-cord guide and a few USB connections who can confirm the host plug..
A USB-C dock, HDMI or Ethernet, full-size SD, or anyone requiring a specific charging rate.
Pros & cons

Full review: how the features affect your choice
What the features mean for you
Consider it for a desktop mouse-and-peripheral setup
Microless describes the ERK-USB3-310 as a three-port USB 3.0 hub with a mouse-cord bungee and RGB lighting. The bungee makes it a desk-oriented accessory rather than a plain travel adapter. It may suit a fixed setup where managing a wired mouse and adding a few USB connections are both useful. The bungee does not add data ports, and the source does not list HDMI or Ethernet. Count only the three USB ports when deciding how many peripherals can connect.
Confirm the upstream plug before choosing a cable
The inspected Microless page identifies the model and downstream features but does not state the host connector shape. That is an important gap: the right port count cannot help if the included upstream plug will not fit the computer. Check the current product's physical cable and connector before ordering, especially if your setup uses a USB-C-only laptop. This review leaves the host-connector profile unknown instead of inferring a USB-A or USB-C plug from the product category.
Treat the reader as MicroSD/TF unless the panel proves more
Microless describes a microSD/TF reader. Its broader title uses the phrase card reader, but the detailed text inspected does not establish a full-size SD slot, card capacity limit or simultaneous access. A user transferring from a standard camera SD card should verify the port panel or plan a separate reader. The saved product information supports MicroSD/TF access only; it does not promise a particular card speed or prove that the reader handles every format.
Keep the 5Gbps statement separate from observed performance
The seller describes three USB 3.0 ports up to 5Gbps. That is an interface claim, not a measured result for this hub with a specific drive and computer. The page does not explain whether attached ports share throughput or what happens with simultaneous high-demand devices. For keyboards and a mouse, the port count may be the practical detail; for an external SSD, verify the exact host, cable and drive limits. No speed test was performed for this review.
Ask what fast charging means for this model
Microless uses the phrase fast charging but does not give a wattage, current per port, power adapter or behavior under simultaneous use. That does not establish USB-C PD or a computer charging path. If charge rate matters, ask for the exact power supply and port ratings on the current ERK-USB3-310 listing. Do not plan around a generic fast-charging phrase or assume that three USB data sockets can each deliver a particular current.
Check the bungee location and current model listing
The seller describes an aluminum body and textured rubber base and says the bungee arm holds a mouse cord above the desk. Consider where the arm will sit, how the mouse lead will approach it and whether the hub's cable reaches the host. These are listed design details, not evidence of tested durability or better mouse movement. The Microless record does not map historical ASIN B07KQX347R to the exact model, and Amazon was unreadable; search by ERK-USB3-310 and compare current photos.
Keep lighting and cable management separate from hub performance
Microless describes pulsating RGB lighting and a mouse bungee as part of the desk accessory. These features may matter for placement and cable organization, but they do not establish the USB host connector, charging capacity or sustained data behavior. Choose the product for those physical functions only if the available surface and cable route suit the setup. A buyer comparing it with a plain hub should weigh the listed three-port expansion and reader separately from lighting, and should verify any performance requirement in the current product documentation.
