Our take
GM-4XA3510-TS is a small four-port USB-A hub in Gearmo's Travel Series. The manufacturer data sheet confirms the downstream connector type, USB 3.2 Gen 1, GL3510 chipset, 5Gbps maximum link, bus-power support, standalone charging, and a 5V DC input. USBGear adds the fixed USB-A host lead and its length. The buyer-facing distinction is ordinary USB expansion with an incompletely documented optional power connection, not a display or laptop-charging dock.
A laptop or desktop user who needs four USB-A ports and can verify the host cable and optional 5V power arrangement on the current offer..
Do not choose it for USB-C host-only computers, HDMI, Ethernet, card readers, or a confirmed included 5V adapter without checking the current offer.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Gearmo's sheet verifies the model and four Type-A downstream ports.
- The data sheet lists bus power and standalone use with a 5V DC input.
- The catalog describes a compact body and fixed host lead.
What to weigh up
- The sheet does not identify the 5V connector or adapter inclusion.
- A fixed USB-A cable is documented by USBGear rather than the maker sheet.
- The historical ASIN is not mapped to a current exact offer.

Full review: how the features affect your choice
What the features mean for you
Add four Type-A ports to a suitable host
Gearmo's technical sheet identifies four downstream USB Type-A ports using USB 3.2 Gen 1. That layout can suit a laptop or desktop that still uses USB-A peripherals such as a mouse, keyboard, flash drive, or card reader. USBGear describes a fixed USB-A host lead about 20 inches long, which can help position the compact hub near the computer. Check the current offer photos and host cable before ordering because the manufacturer sheet does not fully describe the cable assembly or map the old Amazon identifier.
Treat the link rate as a shared specification
Gearmo lists a maximum data rate of 5Gbps and a GL3510 chipset. These are interface specifications, not measurements of file-copy performance. The hub shares an upstream connection among four ports, and each attached device and host also needs to support compatible USB modes. For mixed accessories, that may be enough to add sockets, while several storage devices moving data at once may share the available path. Use the 5Gbps figure as a ceiling in a comparison, not a promise of four separate 5Gbps channels.
Read the 5V power information carefully
The data sheet says the hub can be bus powered, can work without a host as a standalone charger, and has a 5V DC input. It does not identify the DC connector, state whether an adapter is included, or explain how the standalone mode is wired. This evidence supports both bus-power and a listed 5V input, but the precise power accessories remain unresolved. Check the current model's port and package information before relying on external power for a particular peripheral. No host-side charging output is listed for this product.
Keep its role to USB expansion
The saved manufacturer sheet and catalog describe a USB hub with four Type-A data ports, not an HDMI dock, Ethernet adapter, or card-reader station. Those missing roles matter when comparing a small hub with a larger multiport adapter: if the computer needs display output or wired networking, this product does not supply a documented path for them. The record also does not establish a laptop charging function. Use it to solve a shortage of USB ports, then add separate equipment only if the rest of the desk requires other connections.
Check the fixed cable and current listing
USBGear lists a fixed USB-A upstream lead, a 20-inch cable, and GL3510 chipset, while Gearmo's own sheet confirms the product model and port count. These sources should stay distinct: the cable length is a catalog claim, and the manufacturer sheet does not identify the same details. Historical ASIN B094BK738H was not mapped to a current exact Amazon offer. Search by GM-4XA3510-TS and compare the cable and port layout. No price, stock, buyer-review summary, or independent speed result is included here.
Choose it for a compact peripheral routine
The 2.36-inch square body and four downstream Type-A ports can keep a small group of ordinary peripherals together without the extra display, network, and charging functions of a docking hub. The data sheet lists plug-and-play operation and compatibility with older USB devices, but actual behavior still depends on the computer and connected equipment. If an accessory has its own power supply or a specific current requirement, follow its instructions. This model is a narrow solution for adding ports; the 5V input details and included equipment should be checked before buying.
