Anker 332 A8355 USB-C Hub: 4K HDMI and 85W Pass-Through Charging

The Anker 332 A8355 USB-C Hub is for laptops that have enough performance but not enough ports. It turns one USB-C connection into five useful ports: HDMI, one USB-C data port, two USB-A data ports, and a USB-C Power Delivery input. Amazon’s exact B0BQLLB61B listing was $24.99, in stock, rated 4.4 stars from 18,869 reviews, and showed 10K+ bought in the past month at fact-check time.

The appeal is not that it replaces a full desktop dock. It is that the 332 stays small while covering the connections many thin laptops leave out. Anker lists the hub at about 4.78 by 1.59 by 0.45 inches and roughly 1.4 ounces, so it is easy to keep in the same bag as a laptop charger.

Five ports solve the common laptop shortage

The port mix is straightforward. You get two USB-A 3.2 Gen 1 data ports and one USB-C 3.2 Gen 1 data port, all rated up to 5 Gbps, plus one HDMI port and one USB-C PD input.

That layout works well for a keyboard, mouse, flash drive, external SSD, or other everyday USB accessories while still leaving HDMI available for a display. Anker specifically recommends using a USB-A port for a Samsung T7 SSD when stable data transfer is the priority.

There is an important distinction between the two USB-C ports. The 5 Gbps USB-C port is for data and does not output video. The PD input is for laptop power and does not act as another data port. Buyers who expect every USB-C socket to handle data, charging, and display should know that before ordering.

HDMI tops out at 4K at 30Hz

The HDMI 1.4 port supports up to 3840 by 2160 at 30Hz. That is useful for office apps, web work, presentations, video playback, or a secondary productivity screen, but it is not a 4K 60Hz gaming or high-refresh docking solution.

Anker’s support guidance also says the host device’s USB-C port needs DisplayPort Alt Mode for external display output through the hub. If a laptop’s USB-C port is data-only, adding this hub will not create video capability that the laptop itself lacks.

For lower resolutions, Anker documents 1080p at up to 60Hz. That makes the 332 a sensible choice for a common 1080p office monitor even if 4K@30Hz is the headline specification.

85W pass-through charging needs your own charger

The PD input accepts up to 100W. The hub uses part of that power for its own operation, so Anker rates maximum laptop pass-through at 85W. A wall charger is not included, which means the charging benefit only matters if you already have a suitable USB-C PD charger and cable.

This is a useful setup for a desk where you want one USB-C cable connected to the laptop while the hub handles power, USB accessories, and HDMI. It is less useful if you expected the hub itself to function as a charger.

Anker also notes that the hub can become warm during high-speed charging or data transfer. The company says this is within normal operating limits and advises against covering the hub while it is working.

Who should buy the Anker 332 A8355?

The 332 fits buyers who want an inexpensive, compact USB-C hub for one external display, a few 5 Gbps accessories, and pass-through laptop charging. It is especially sensible for a MacBook, Dell XPS, Lenovo ThinkPad, or similar USB-C laptop when HDMI and legacy USB-A ports are the main missing connections.

Skip it if you need Ethernet, SD or microSD card slots, multiple external displays, 10 Gbps USB, or 4K at 60Hz. Those needs call for a larger hub or docking station with more bandwidth and ports.

At roughly $25, the Anker 332 works because its limits are easy to understand. It is not trying to be a desk-sized dock. It is a light 5-in-1 adapter that gives a compatible USB-C laptop HDMI, three data ports, and up to 85W of pass-through power without adding much bulk to the bag.
