Our take
Choose the Knox Gear KN-USB7P20 if you want seven basic USB 2.0 connections with an individual switch and status LED for each port. Its main compromise is that the inspected records do not show the exact host plug, a current power budget, or charging support. Treat it as a peripheral hub, not a high-speed storage or laptop-charging solution, and verify the cable and offer before ordering.
A buyer who needs several modest-bandwidth USB peripherals and wants individual port controls, provided the current offer's host cable suits the computer..
It is not a good fit for frequent large-file transfers, USB-C docking, video or Ethernet output, or charging devices where a specific current rating matters.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Focus Pro Audio and Walmart Business independently identify model KN-USB7P20.
- The product descriptions name seven USB 2.0 ports, each with an individual switch and LED.
- The controls can make it easier to manage connected peripherals at a fixed desk without reaching behind the computer.
What to weigh up
- USB 2.0 is slower than the USB 3.x connections suited to frequent large-file transfers.
- The inspected records do not establish an external adapter, total power budget, per-port current, or charging support.
- The exact host plug and the relationship to historical Amazon ASIN B07NPDP9RW remain unconfirmed.
The key details
| Model covered | KN-USB7P20 |
|---|---|
| Host connector | The upstream plug shape and included computer cable are not specified |
| USB 3.x data ports | Seven downstream USB 2.0 data ports; no USB 3.x ports are documented |
| Installation | Universal cabled hub; confirm the exact host connection in the current offer |
| Hub power | Included-items list names the hub and warranty, not an external power adapter |
| Host charging | Charging support, port current, and power delivered to the computer are unspecified |

What the features mean for you
Seven clearly specified USB 2.0 connections
The verified model is a straightforward Knox Gear USB 2.0 hub that expands a compatible host connection into seven downstream ports. Its role is basic peripheral connectivity: a keyboard, mouse, printer or other modest-bandwidth device can remain connected without repeatedly changing cables. USB 2.0 is an older, slower interface than USB 3.0, so this is not the profile to select for frequent large-file transfers or high-speed external storage. The name and model code are corroborated by retail records, but those sources do not provide a detailed mechanical drawing or the exact upstream cable connector. Check the offer and included cable before ordering.
Individual switches and LEDs aid desk control
The product descriptions identify a separate power switch and status LED for each port. These controls can help a user disconnect a peripheral's hub connection without reaching behind a computer, and an LED can make it easier to see which ports are enabled. The sources do not explain whether a switch fully isolates data, cuts power in every operating state, or changes the total current available to the other ports. Treat the switches as a convenience feature rather than proof of per-port power regulation. They may be useful in a workspace with stationary peripherals, but a buyer who needs synchronized charging or a managed power budget should seek explicit specifications.
USB 2.0 speed is the central trade-off
All seven downstream ports are identified as USB 2.0, placing this hub behind products that offer USB 3.0 or faster links for storage. That can still be a sensible fit for peripherals whose demands are modest, such as input devices and some printers. It is less suitable for moving large files or attaching several high-bandwidth devices. The product title does not claim video output, Ethernet, card readers or USB-C docking. A buyer should match the hub to data needs instead of choosing it by port count alone: seven slow ports do not substitute for a smaller number of faster ports when throughput matters.
Power support is not documented well enough for charging decisions
The Focus listing's included-items section names the hub and a one-year warranty, but no external supply, input rating or per-port current table. It also does not state that the hub is designed to charge phones or tablets. The individual switches do not establish that ports can deliver a particular charging current. Buyers should use this profile for peripheral expansion only unless the exact current offer supplies a compatible, documented power adapter and charge rating. If the host port alone powers the hub, a connected device's demand can affect stability; the inspected sources do not give a supported total-load threshold. Do not infer charging performance from “USB 2.0” or the seven-port count.
Compatibility claims come from an older specification page
Focus Pro Audio lists support for older Windows, Mac OS X and Linux versions. That is evidence of broad historical compatibility but not a promise for every current computer, console or operating-system release. USB host standards and driver behavior can vary, and the product page does not identify a special driver requirement or a current compatibility matrix. A buyer should verify the computer's USB connection, operating-system support and cable fit with the current seller. The hub is most straightforward where a standard USB peripheral path is sufficient and no display, network or charging function is expected. The page does not document those additional dock roles.
The exact model is verified, while the frozen ASIN remains separate
Focus Pro Audio uses the Knox Gear product name and a merchant SKU built around KN-USB7P20, while Walmart Business independently lists MPN KN-USB7P20. That combination verifies a real seven-port USB 2.0 model, but neither inspected record links it to historical Amazon ASIN B07NPDP9RW. The tagged search uses the model code so shoppers can compare a current Amazon result against the verified name, port generation, switches and LEDs. This review relies on product records, not personal testing, review aggregates, present-day inventory, current pricing or sales claims. Choose it when seven basic USB connections and local on/off controls matter more than speed or a documented charging budget.
What else to compare
Before you buy
How many USB 3.0 ports does it have?
None are documented; the inspected records identify seven ports as USB 2.0 and do not specify any USB 3.x ports.
Does it include an external power supply?
The Focus listing's included-items section names the hub and a one-year warranty but does not list an external supply.
Is B07NPDP9RW confirmed as KN-USB7P20?
No. The inspected Focus and Walmart records corroborate the model but do not map the frozen ASIN to it; use the tagged exact-model search.
Where can I check the current price?
Use the Amazon link for current offers. Check the exact model, seller, product condition, delivery, and return terms. This page does not display a live price or confirm stock.

The decision
Choose the Knox Gear KN-USB7P20 if you want seven basic USB 2.0 connections with an individual switch and status LED for each port. Its main compromise is that the inspected records do not show the exact host plug, a current power budget, or charging support. Treat it as a peripheral hub, not a high-speed storage or laptop-charging solution, and verify the cable and offer before ordering.
