Anker PowerExpand+ USB-C to HDMI Adapter: Compact 4K Video Adapter
The Anker PowerExpand+ USB-C to HDMI Adapter (model A8312, also known as the Anker 310 USB-C Adapter) is a slim, portable dongle from Anker’s PowerExpand+ series, launched in 2019 and still a bestseller in 2025 for turning USB-C ports into HDMI outputs. Ideal for professionals, gamers, and travelers needing quick screen mirroring or extension without bulky hubs, it’s praised for its reliability and build quality. Weighing under 10g and just 0.5 inches thick, it’s smaller than an AA battery and slips easily into a pocket or laptop bag.
Key Features
- Vivid Video Output: Supports resolutions up to 4K@60Hz for smooth streaming, presentations, or gaming on external monitors, TVs, or projectors. Mirror or extend your display seamlessly.
- Plug-and-Play Simplicity: No drivers or software needed—just connect your USB-C device to the adapter and HDMI cable to start.
- Premium Build: Aluminum alloy casing for heat dissipation and durability; braided-nylon cord withstands 10,000+ bends and tugs. Rustproof connectors ensure long-term reliability.

- Average Rating: 4.6/5 stars across 50,000+ Amazon reviews; 4.7/5 on Target and Newegg.
- Pros: Users love the sharp 4K video, zero-lag performance, and sturdy construction—perfect for MacBook users extending to external monitors or travelers hooking up to hotel TVs. “Plug in and forget—flawless for presentations,” says one reviewer.
- Cons: Occasional handshake delays with older TVs (under 1 second); doesn’t support audio over USB-C on non-Thunderbolt devices (HDMI handles it); not ideal for dual monitors (see Anker’s dual HDMI adapter for that). Some note it’s picky with non-Alt Mode ports, so check compatibility first.
