It is particularly favoured by professionals, students, and frequent travellers who need to connect external displays, transfer data from flash drives, and charge their laptop – all at the same time.

Weighing only 40 grams, it is slim enough to slip into any laptop bag or even a pocket. The hub features a 100W Power Delivery (PD) input for pass‑through charging (providing about 85‑90W to your laptop while using 10‑15W for the hub itself), a 4K HDMI output at 30Hz for external monitors or TVs, and a USB‑A 3.0 port with data transfer speeds up to 5 Gbps.

The premium aluminum shell acts as a heat sink, preventing overheating during heavy use. It is compatible with a wide range of USB‑C devices, including MacBook Pro/Air, iPad Pro, Dell XPS, and Microsoft Surface Pro 7 (provided the host device supports DisplayPort Alt Mode for video output). The Anker PowerExpand 3-in-1 is the perfect solution for eliminating dongle clutter and adding essential ports to modern ultrabooks.

The Anker PowerExpand 3-in-1 is engineered for users who demand essential connectivity in a compact, travel-ready package. Whether you are a professional who needs to connect an external display for presentations, a student who needs to transfer files from a USB drive, a frequent traveller who needs a lightweight hub for on-the-go use, or someone who values premium aluminum construction and heat dissipation, this hub is built to meet your needs.

The combination of 100W PD pass-through charging, 4K HDMI output, and 5Gbps USB-A data transfer makes it one of the most practical and portable USB-C hubs available today.

For Android users, this hub works with USB‑C Android tablets and phones that support DisplayPort Alt Mode (e.g., Samsung DeX devices), integrating seamlessly with the Android ecosystem .

The pass‑through design means you do not lose a charging port when using the hub – a common frustration with some USB‑C adapters. You can connect your 100W or 65W charger to the hub, then the hub to your laptop, and still have access to HDMI and USB‑A.

Heat management:

• Aluminium heat sink: Efficient heat dissipation.

• No excessive heat: Even at high power.

• Safe operation: Protects internal components.

• Extended lifespan: Prevents thermal damage.

The hub does not generate excessive heat even at high power thanks to its aluminium heat‑sink design. The Power Delivery feature supports the USB‑C PD standard, which negotiates voltage and current based on your device’s requirements, ensuring safe and efficient charging.

For Android users, the 100W PD pass‑through ensures efficient power delivery within the Android ecosystem .
