Our take
A clearly separated four-port data hub and charging socket for a USB-A desk, with useful per-port switches and a modest total charging-current limit.
A USB-A desktop user who needs four switched USB 3.0 data ports, more cable reach than a compact dongle and a separate low-power device-charging socket..
Laptop charging, high-current multi-device charging, or users who need five computer data ports.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Four USB 3.0 data ports have individual switches and switch-state memory.
- A separate charge-only port and included 5V/3A adapter are documented.

What to weigh up
- Total charging current across devices must not exceed 3A.
- The separate charge socket is not a fifth data port.
- Some 2.4GHz peripherals may require a direct computer connection.

Full review: how the features affect your choice
What the features mean for you
Separate the four data ports from the charging socket
The five visible downstream connections do different jobs: four USB 3.0 data ports and one separate smart charging port. That distinction matters if the goal is to attach several computer peripherals while also charging a phone. The bottom charging socket is described as charging-only; it should not be counted as a fifth computer data port. Tendak advertises up to 5Gbps on each of the four data ports and rates the separate charging output up to 2.4A. Those are manufacturer specifications, not measured concurrent speeds or a per-device charging guarantee.
Use the switches when devices do not need to stay connected
Each data port has its own on/off switch, and Tendak says the hub remembers each switch setting after it is powered down. This helps when a desk has devices that can remain plugged in but do not need to stay powered all day. Four blue LEDs indicate the port states. The control applies to the four USB data ports; the product page describes the bottom charging socket separately. The switches add manual control, but this is not a hub with software-based device switching or a stated per-port power meter.
Plan for the adapter and the total current limit
Amazon lists the power adapter as included, and Tendak specifies a 5V/3A adapter. The manufacturer cautions that the total charging current across multiple devices must not exceed 3A. Its page says the charging port can operate while the computer is off when the adapter is connected. This is useful for low-power desk peripherals and a phone, but it is not a high-wattage USB-C charger. Add the needs of all attached devices together instead of treating 2.4A on the dedicated charge port as a 2.4A promise for every port simultaneously.
Check device compatibility and cable reach
The product has a one-meter/39-inch lead, giving more placement flexibility than a compact directly attached hub. Tendak lists Windows, Mac OS X and Linux support, and says the data ports are backward-compatible with USB 2.0/1.x. It also warns that some USB 3.0 devices and 2.4GHz wireless peripherals may need a direct connection to the computer. If a wireless keyboard or mouse receiver is essential, plan to test it in the intended port or keep a host port available.
Confirm the CP-029-BK identity
Amazon's product detail identifies B00VK9C24M as model CP-029-BK and part CP-029-BK-VC, while Tendak's own product page lists SKU CP-029-BK and the same four-data-plus-one-charge design. This exact match supports a tagged direct Amazon link. It is not the same verified identity as the unresolved CP-029-BK-NP row in the frozen history; compare the model code and port diagram. This review paraphrases manufacturer specifications and includes no personal testing, buyer-rating summary, current price or availability claim.
