Targus DOCK402 combines a mobile dock with a built-in GaN charger. Its useful buying checks are host power negotiation, USB-C video support and the single-display limit, rather than assuming every USB-C laptop gets the maximum charging and resolution.
One travel device can be easier to pack than a charger and a separate hub, provided it supports the laptop you actually own. Targus DOCK402 combines those roles, but the maximum power figure and the maximum display mode each have their own compatibility conditions.
Check USB-C video support, negotiated charging and the single HDMI output before buying.140 W needs compatible PD3.1 EPR equipment, and bus-powered mode does not charge the host. A separate ASUS Vivobook Go 15 Corei 3 laptop was R8,499 on 28 October; that is local laptop context, not a dock price or a compatibility endorsement.
The built-in GaN charger can replace a separate power brick in a suitable setup. It still needs wall power to provide its own charging output. The application note distinguishes AC-powered operation from bus-powered operation, where the host instead supplies the dock. Those modes solve different problems, so confirm the selected mode when charging is unexpectedly absent.
The 140 W headline depends on USB PD3.1 Extended Power Range support and the appropriate cable. A PD3.0 host has a different negotiated ceiling. Connected peripherals also draw from the available budget, so do not assume the largest advertised laptop figure remains available with every downstream port loaded. Compare your existing laptop's requirements before deciding to leave its original charger at home.
DOCK402 is a single-display design with an HDMI output advertised up to 8K at 30Hz. That is not a promise that every connected computer will expose that mode. The host's video capability, cable and monitor must all support the requested connection. A USB-C socket's shape alone does not establish DisplayPort Alternate Mode support.
Start with the resolution and refresh rate of the screen you use now. If you need two external monitors, do not mistake a product family's broader docking range for this model's own port list. Browse monitors on special around a known working output plan. A high-resolution label is little help if the desk requires a second independent connection that the dock does not provide.
The announcement lists three 10Gbps USB ports and 1Gbps Ethernet. Treat those as connection capabilities rather than guaranteed transfer speed for every peripheral or network. A storage device, cable or network link can impose a lower practical limit. List the devices you connect together and consider which ones need power as well as data.
The application note advises an uncovered, stable placement because the dock includes a power stage. Do not plan to leave it enclosed in a bag while using it. A tidy desk connection should still allow airflow and access to the cables. Test the full setup before relying on it away from home, including reconnecting after you change operating modes.
Targus's 27 October launch announcement follows a September application note and earlier range previews. This is the current release milestone, not a claim that the model was previously unknown. Neither that announcement nor an overseas listing establishes the final South African package, price or supplied mains lead.
For laptop shopping, use all laptops on special to compare the exact host model's ports and charging requirements. TheR8,499 Vivobook example is a different product from the dock and is not proof that its USB-C connection supports the needed functions. Keep laptop capability, dock capability and monitor capability as three separate checks before spending money on a combined travel solution.
No. The application note requires a host with DisplayPort Alternate Mode for the dock video connection.
No.140 W requires compatible USB PD3.1 EPR hardware and cabling. PD3.0 hosts negotiate up to 100 W.
The specified design has one HDMI display output. Do not buy it as a dual-HDMI dock.
No. The host supplies the dock in that mode, so the dock is not charging the host.
Yes. The manufacturer describes dynamic allocation of the available power budget as downstream devices connect.
No. It is a dated ASUS Vivobook Go 15 laptop reference, included only as local buying context.

A 2700RPM pump spins its impeller 2700 times a minute to push coolant round the loop. Faster flow moves heat from the CPU block to the radiator, though a quicker pump can be a little louder. The Antec Omni Matrix 360 at R999 pairs it with an ARGB head.
Plug the three pre-connected 120mm fans into one PWM fan header, since they run from a single cable. If the lighting has its own lead, send it to the addressable header, usually labelled ARGB. Evetech's Omni Matrix 360 at R999 follows that same plan.
Compatibility starts with your motherboard socket. The Antec Omni Matrix 360 covers LGA 1851 and LGA 1700 sockets, as well as AM5 and AM4. Confirm the socket name before you open the box, since the mounting hardware differs between platforms.
A PWM fan changes speed on a board signal, while a fixed-speed fan runs at one rate. PWM lets a curve ramp up under load and stay quiet at idle. In a small flat in Durban with a shared lounge, quiet idle curves matter, and the Omni Matrix 360 uses PWM fans.
Edge sleeping tabs reduce the resources used by inactive pages. Review the setting and important-site exceptions before disabling it, and test live work separately from pages you only keep for later.
Open Google Earth Pro on a Windows PC and press Ctrl+Alt+A to fly an F-16 or SR22 over real terrain. Keyboard flying over Table Mountain is a fun taster, and a USB stick like the R3,999 Turtle Beach VelocityOne Flightstick is where proper sims begin.
Yes for clips, trim, mounts and brackets, but never for brakes, steering or seatbelts. A parked car in a South African summer gets hot enough to soften PLA, so PETG from R219 a spool or ABS at R299 is the safer choice for anything that lives inside the cabin.
An extender fixes weak WiFi on a Vuma line only when a room or two sits just past the router's reach. Vuma runs the fibre but your ISP supplies the router, and a R919 TP-Link RE450 suits a small gap, while brick double-storeys need mesh or a cabled access point.

Why DDR5 cheaper than DDR4 in SA for gamers should be shortlisted around the job it must do. South African buyers should compare fit, performance, compatibility, and upgrade room, warranty path, and upgrade room before treating any pick as best.
