Our take
THX-050300KD is a better-documented choice for someone who wants several USB 3.0 data sockets, a separate phone-charge port, external power and individual data-port switches. It is a poor fit for USB-C host input, laptop PD, video, Ethernet, card reading or known per-port power guarantees. Its manual is reproduced by a third-party host and does not establish simultaneous-load performance.
A desktop user who wants four switched USB 3.0 data ports, external hub power and a distinct phone-charging socket, and can confirm physical host fit separately..
Skip it if you need a verified USB-C host connector, laptop charging, video, Ethernet, card reading or a guaranteed per-port current under load.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Exact Amazon ASIN and THX-050300KD model are paired.
- Four USB 3.0 data ports are distinguished from one charge port.
- The manual specifies individual data-port switches and a 5V/3A adapter.
What to weigh up
- The SmartCharging port is not a fifth data connection.
- Per-port output and simultaneous-load performance are not verified.
- Host and downstream connector shapes are not identified in the retrieved manual table.

Full review: how the features affect your choice
What the features mean for you
Keep data transfer and device charging on their intended ports
The THX-050300KD manual describes a five-port hub with four USB 3.0 data ports and one separate SmartCharging port. That split matters: the red charging socket is presented for charging devices, while the four blue sockets carry data. Someone shopping for four extra data connections should count only the four USB 3.0 sockets, not all five. Someone looking to charge a phone can use the dedicated charging socket, but it is not a fifth data port. Check the physical labels on the selected unit and do not plan to attach a data device through the charge-only connection. The instructions specify up to 2.4A on the smart-charge port, not a modern USB-C laptop charging function.
A powered design can help with peripheral power needs, within its limits
The Amazon title lists a 5V/3A, 15W adapter, and the THX-050300KD manual specifies a 5V/3A power input. External power avoids asking the computer's USB socket to supply all of the hub's operating power, which can be useful when several peripherals are attached. It does not establish a guaranteed current limit for each data port or a measured result with multiple high-draw devices. Check the power rating on the adapter supplied with the chosen offer and confirm that it is the intended model. Storage devices with substantial startup demand, phones, and small accessories place different loads on the hub. The source provides no independent multi-device stress test, so this review does not promise stable performance under every load.
Individual switches simplify a fixed desktop setup
The manual describes an independent on/off switch and LED for each USB 3.0 data port. That can be convenient when a printer, keyboard, storage device or other accessory stays plugged into the hub but should be disconnected from bus power without removing its cable. The instructions say to tap the button to activate a port and hold it for roughly two seconds to turn it off. This is a control feature, not a data-isolation or security certification. The manual does not establish whether the dedicated charging port has an independent switch with the same behavior, so treat the switch claim as applying to the data sockets described in the instructions.
Match the host and device speed before expecting USB 3.0 throughput
The manual specifies up to 5Gbps for the four USB 3.0 data ports and backward compatibility with USB 2.0 devices. That is the interface's nominal maximum, not a promise of actual file-transfer speed. The computer port, cable and attached peripheral also need to support the higher standard. A USB 2.0 flash drive remains limited by its own interface even when connected to a USB 3.0 hub. Avoid describing these sockets as USB-C: the product evidence calls them USB 3.0 data ports but the retrieved manual does not explicitly identify the connector shape in its specification table. The hub also has no verified Ethernet, video, card reader or laptop PD feature.
Who should consider this powered hub
The exact Amazon page and model record make THX-050300KD a better-documented choice for someone who wants several USB 3.0 data sockets, a separate phone-charge port, external power and individual data-port switches. It may be a poor fit for someone who needs USB-C host input, direct laptop charging, video, network or memory-card access, or measured per-port power guarantees. The exact affiliate destination points to B01FO2QS0O because Amazon's item page and details identify that same model. The evidence does not establish current stock or price, and the review reflects specifications rather than personal testing.
