Quick Answer
In docking stations, USB-C Power Delivery and USB data ports do different jobs, so neither universally wins: PD wattage matters more if you want the dock to charge your laptop, while USB ports and bandwidth matter more for connecting drives and peripherals. For a single-cable desk, prioritise 90W-plus PD and a 40Gbps Thunderbolt 4 or USB4 link (R3,500-R6,000).
What USB-C Power Delivery does
USB-C Power Delivery is how the dock charges your laptop over the same cable that carries data. The PD wattage decides whether your machine charges while docked: a thin laptop is fine on 60W, but a powerful one needs 90-100W, and an underpowered dock will trickle-charge or fail to keep up under load. If your goal is a clean single-cable setup where one connection charges and connects everything, PD wattage is the spec that matters most, so confirm it against your laptop's charger rating.
What USB ports and bandwidth do
The USB ports handle your peripherals and storage, and the underlying bandwidth decides their speed. Basic USB-C docks run ports at 5-10Gbps, fine for keyboards, mice and slower drives, while Thunderbolt 4 and USB4 docks offer 40Gbps for fast external SSDs and dual-display output. So if you connect fast storage or two 4K screens, bandwidth and port type matter more than charging. Most buyers want both: enough PD to charge and enough bandwidth for their devices, which points to a quality Thunderbolt 4 or USB4 dock.
Buying it in South Africa
Evetech ships docks nationwide, and a balanced single-cable dock with 90W-plus PD and 40Gbps sits at R3,500-R6,000, while a USB-C dock for lighter needs is R1,200-R2,500. Decide whether charging or fast data is your priority, then match the dock's PD wattage and bandwidth accordingly. Confirm both specs against your laptop and devices on the product page so the dock does exactly what you need.
FAQ
Is PD wattage or USB bandwidth more important?
It depends on your goal. PD wattage matters most if the dock should charge your laptop, while USB bandwidth matters most for fast drives and dual displays. Most buyers want enough of both.
What PD wattage does my laptop need?
Match it to the charger. A thin ultrabook charges on 60W, but a powerful laptop needs 90-100W to keep up under load, so an underpowered dock will trickle-charge it during work.
When do I need 40Gbps over a basic dock?
For fast external SSDs and dual 4K-60 displays. Basic USB-C docks run at 5-10Gbps, which suits peripherals and slow drives, but high-bandwidth storage and dual screens need Thunderbolt 4 or USB4 at 40Gbps.
charging or fast data is your priority, then match PD wattage and bandwidth. A good single-cable dock delivers both at once.
