Your needs, this model
Does it fit your priorities?
Can I use one 4K30 HDMI screen and two 5 Gbps USB-A data accessories?
Yes, in the documented compatible USB-C host arrangement. The USB-A ports are advertised at 5 Gbps and share the stated accessory-power budget.
Explore this need in the finder →Does it have a separate USB-C data socket while charging the laptop?
Yes. The data USB-C socket and PD input are separate. Up 85 W laptop delivery is advertised with a suitable source; an included charging kit is not established.
Explore this need in the finder →Does it include Gigabit Ethernet and a full-size SD reader?
No. Neither function is present in the complete five-role port map. Choose another layout when those connections are essential.
Explore this need in the finder →A focused one-screen hub with three useful data connections
The Anker 332 A8355 combines one HDMI output, two USB-A data sockets, one USB-C data socket and a separate USB-C PD input. It is a reasonable port mix for a compatible laptop owner who wants one screen and a small group of peripherals while retaining the option to charge through the hub.
The omissions are straightforward: there is no Ethernet socket or card reader in the complete five-function layout. If wired networking or importing camera cards is central to your routine, account for another accessory or choose a different hub. A five-port headline is useful only when those particular five roles match what you need.
HDMI is a single 4K30 route
Anker specifies HDMI 1.4 output up to 3840 × 2160 at 30 Hz and describes mirroring or extending to an external monitor. That is a single-screen arrangement. It is not a two-monitor dock, and its 4K label should not be read as a 60 Hz refresh-rate promise.
The USB-C data socket does not provide another native video connection in the complete port map. Choose a documented multi-display arrangement if two independent external desktops are essential. Adding the visible USB-C sockets to the HDMI socket is not a valid way to count display outputs.
Check the computer's actual USB-C display capability as part of the purchase. The manufacturer's generic laptop examples are not a substitute for the exact computer port, supported software and display connection. A USB-C-shaped connector can have a different role from another socket that looks the same.
Two USB-C sockets have different jobs
The downstream USB-C data socket is advertised at up to 5 Gbps. The other USB-C socket is PD input for the charging source. Keeping those roles separate makes the layout useful: you can reserve the data socket for a compatible accessory while connecting the appropriate power source to the dedicated inlet.
Anker lists a 100 W input ceiling and up to 85 W laptop output. Those are different points in the power path, not interchangeable figures. Plan a suitable source and charging cable, and check what the computer accepts, rather than assuming the hub itself supplies power independently.
The product page is not a complete included-charger specification. Do not choose this listing as an assured all-in-one charging kit without checking the selected package. The supported charging function and an included suitable power adapter are separate requirements.
Read the data and accessory-power figures together
Both USB-A data sockets and the USB-C data socket are specified at up to 5 Gbps. The current table also gives a total of 4.5 W, or 5 V at 0.9 A, for the USB-A data-port group, while the USB-C data socket is listed at 7.5 W, or 5 V at 1.5 A. Do not turn a group total into an independent allowance for each USB-A socket.
These figures are useful when checking a device's stated demands, but they are not evidence that every drive or accessory combination works. The data sockets share the hub's upstream connection as well. Advertised line rates do not represent measured file-copy speeds or three independent full-speed paths to the computer.
A specific storage-device note is worth following
Anker advises connecting a Samsung T7 SSD to the USB-A ports for stable data transfer. That is a concrete model-specific instruction, rather than permission to assume every USB-C drive belongs in the USB-C data socket under every arrangement. Check the accessory guidance if that drive is part of the intended setup.
The manufacturer also recommends connecting a wall charger for an optimal experience with named devices including Surface Go, ASUS CM3 Tablet, Galaxy S23 Ultra, Galaxy Tab S7+ and LG V60. Such notes describe specific source requirements or workarounds; they do not establish a universal compatibility promise for all devices in those broad families.
Keep the computer scope specific
The current product page names MacBook Pro, MacBook Air, Dell XPS, Lenovo ThinkPad and HP laptops as compatibility examples, but it does not establish each individual Apple chip or every operating-system version in the material reviewed. Follow the exact computer requirements before making a generational claim from a broad family name.
Shortlist A8355 for a supported one-HDMI routine with two USB-A and one USB-C data connections and separately planned laptop power. Choose another model for 4K60, two independent external displays, Ethernet, SD or microSD. Its advantage is a focused set of separate data and power roles, provided those are the connections your actual computer needs.
