Our take
ACH124US is a compact, clearly documented four-port USB-A hub for routine peripherals. Its narrow data-expansion role is more certain than its charging capability, which Targus does not quantify.
A laptop user who needs four USB-A data ports from a documented USB-A host and has no need for video, Ethernet, or card access..
Skip it when the host is USB-C only, when video or Ethernet is needed, or when a specific charging current is a requirement.

Full review: how the features affect your choice
What the features mean for you
Four USB-A ports from one tethered connection
Targus names ACH124US as a four-port USB 3.0 hub and specifies a tethered USB-A host connection. Its product table lists four Type-A ports, so the basic compatibility question is relatively clear for a computer with a free USB-A data port. This is useful for a mouse, keyboard, flash drive, or similar accessories when the laptop lacks enough sockets. It is not a multiport dock: the maker's table lists no HDMI, VGA, DVI, or audio output.
The host port determines which USB rate is available
Targus says the hub defaults to USB 2.0 data transmission rates when attached to a USB 2.0 host. To use the listed USB 3.0 generation, the computer connection, hub, cable, and peripheral all need compatible support. That does not guarantee a particular measured file-copy result; it tells the buyer which interface generation the product documents. If the laptop has only USB 2.0, the extra sockets can still help with basic devices, but the newer interface's ceiling will not be available.
A charging mention is not a charging specification
The product page says a smartphone may be connected to charge and lists overcurrent protection. It does not give a port-current value, fast-charging standard, or total power budget. Buyers should not treat that sentence as a guaranteed phone charge rate or as laptop USB-C PD. A keyboard or mouse has different demands from an external drive, and a hub's four-port count does not tell you how much current each socket can supply. Check the connected device requirements before relying on it for power.
Small dimensions make it easy to place, but not a full dock
The body measures 3.43 by 1.54 by 0.51 inches, which gives it a compact footprint for a work bag or desktop. Targus lists Windows, Mac, and Chrome compatibility. The official specification table records no HDMI, VGA, DVI, or audio ports, and does not list Ethernet or card readers. A buyer who needs a monitor, wired network, or memory-card workflow should select a different model with those functions expressly documented.
Search by ACH124US and compare the current item
The Targus page documents ACH124US, but no source connects it to historical Amazon ASIN B00P937GQ4, whose detail page could not be inspected. Search by the exact model and compare the tethered USB-A cable and four-port layout. This profile does not claim that the old ASIN is a current offer. The assessment uses Targus's own specifications rather than a personal test or summary of customer reviews.
Use it for simple USB expansion rather than charging or display
ACH124US is best suited to a buyer who needs four USB-A connections and can use the computer's USB-A host port. It is not the right choice for someone who wants a monitor output, Ethernet, card reading, or measured charging capacity. The useful trade-off is a small, direct port expander with a clear port count against a lack of dock functions. Confirm that the exact model is offered and that USB 3.0 host support is available if data transfers matter.
