Modern laptops have one or two USB-C ports, and that is it. A USB-C hub turns that single port into a dock for your monitor, keyboard, mouse and charger — but the specs matter.
First, video output. If you want 4K, the hub must explicitly support 4K HDMI at 60Hz. Cheaper hubs often cap out at 4K30 or 1080p, which makes text look soft on large monitors.
Second, power delivery (PD). A hub with 100W PD pass-through plugs into your charger and re-powers your laptop while the hub works. Without it, your laptop drains while connected to a monitor.
Third, data ports. USB-A 3.0 (5Gbps) is the minimum for peripherals. If you edit video from external SSDs, look for USB 3.2 Gen 2 at 10Gbps — most sub-$20 hubs do not have it.
The UGREEN 5-in-1 hub nails the essentials: 4K HDMI, 100W PD, three USB-A data ports, plug-and-play with no drivers, in a compact design that travels in a pocket. It is MacBook compatible and costs less than a lunch for two.
Avoid hubs that get hot to the touch during use — a sign of poor thermal design that can throttle your devices.
A final note on expansion: if you need an Ethernet port or SD card slot, count them before you buy. The price gap between "hub" and "dock" is real, but most people never need the extras.
