USB-C Travel Hubs Compared: Plugable USBC-7IN1 vs USBC-7IN1E
By The Gear Audit Team · Specification research September 10, 2026; buying-advice layout update September 13, 2026.
Quick answer: a third USB-A port or Gigabit Ethernet?
Choose the Plugable USBC-7IN1 when three USB-A ports are more useful than wired networking. Choose the USBC-7IN1E when a Gigabit Ethernet port belongs in the travel kit and two USB-A ports are enough. Both are compact one-display adapters with card readers and USB-C power pass-through. Before buying either, verify that the laptop’s USB-C port supports DisplayPort Alt Mode for HDMI and USB Power Delivery for charging.
Its three USB-A ports suit a travel setup carrying an older mouse receiver, storage, or another USB-A accessory. Check whether the unit is the older 4K 30 Hz revision or revised 4K 60 Hz hardware.
It exchanges one of those USB-A ports for Gigabit Ethernet, which can be more useful in a hotel, office, or lab with a wired connection.

Plugable USBC-7IN1: the three-USB-A travel option
Best for: A laptop bag that needs one HDMI display, SD and microSD readers, power pass-through, and three USB-A connections more than wired Ethernet.
The USBC-7IN1 combines HDMI, three USB-A USB 3.0 ports, SD and microSD readers, and a charging-only USB-C PD input. Plugable documents a built-in 17 cm USB-C host cable, which avoids packing a separate cable but fixes the cable length and connector position. The USB-A ports are listed up to 5Gbps and the UHS-I card readers up to 104 MB/s.
Hardware revision is the central buying check. Plugable documents an older version limited to 4K 30 Hz and a revised version that can reach 4K 60 Hz when the host supplies DP 1.4 Alt Mode and the display and HDMI cable also support the mode. The presence of an HDMI socket by itself does not establish the resolution and refresh rate.
Pros
- Three USB-A ports preserve support for older peripherals. A mouse receiver, flash drive, or another USB-A device can stay connected without immediately adding a second hub.
- Separate SD and microSD readers reduce adapter packing. Camera and mobile storage cards can connect without occupying a USB-A port.
- USB-C PD pass-through can keep a compatible laptop powered. Plugable lists up to 100 W input and up to 92 W to the host, allowing one host cable to carry the hub connection and charging when all devices support it.
Cons and trade-offs
- It has no Ethernet port. A traveler who needs a wired network connection must pack a separate adapter or choose the USBC-7IN1E.
- Two hardware revisions have different display limits. A buyer can receive the wrong capability if the exact revision is not identified before purchase.
- The captive 17 cm cable cannot be swapped for a longer one. Laptop port placement and desk geometry determine whether the hub can rest securely instead of hanging from the connector.
Choose something else if: Wired Ethernet is a routine requirement, the laptop needs more than one external display, or a replaceable host cable is important. The USBC-7IN1E adds Ethernet; a full desktop dock better fits larger display and peripheral setups.
Our recommendation
We recommend USBC-7IN1 when a third USB-A port will be used and wired networking will not. Verify the hardware revision and the laptop’s DisplayPort Alt Mode and Power Delivery support before relying on 4K 60 Hz or pass-through charging.

Plugable USBC-7IN1E: Ethernet in the travel port mix
Best for: Hotel, office, classroom, or lab setups where a wired Gigabit Ethernet connection matters more than carrying a third USB-A peripheral.
The USBC-7IN1E keeps the same broad travel-hub purpose while changing the port mix: HDMI, Gigabit Ethernet, two USB-A ports, SD and microSD readers, and USB-C PD pass-through. It also uses a built-in 17 cm USB-C 5Gbps host cable. The Ethernet port is the deciding addition for a location with a wired network jack or a workflow that should not depend entirely on Wi-Fi.
Plugable lists one HDMI display up to 4K 60 Hz with a compatible DP 1.4 Alt Mode host, while noting that many DP 1.2 hosts are limited to 4K 30 Hz. Its charging path also depends on host USB Power Delivery support, and the host can accept less than the hub’s published maximum.
Pros
- Gigabit Ethernet places wired networking in one adapter. That can replace a separate network dongle in locations where Wi-Fi is unavailable, congested, or simply not the intended connection.
- Two USB-A ports and two card readers cover a practical travel set. The hub can connect common peripherals and removable media while leaving the laptop on one USB-C host connection.
- Power pass-through supports a one-cable laptop arrangement. With a compatible charger and host, the same USB-C connection can serve the hub and deliver manufacturer-listed power to the computer.
Cons and trade-offs
- Ethernet replaces one USB-A port relative to USBC-7IN1. A setup with three simultaneous USB-A peripherals will need another connection plan.
- 4K 60 Hz depends on the complete display chain. A DP 1.2 host, incompatible cable, or display limitation can reduce the documented result to 4K 30 Hz.
- It remains a one-display compact hub. A permanent multi-monitor desk or high-demand storage setup calls for a dock chosen around the host’s display routing and bandwidth.
Choose something else if: You never use wired Ethernet and a third USB-A connection is more valuable, or you need a larger dock with multiple display routes and a replaceable host cable.
Our recommendation
We recommend USBC-7IN1E when Ethernet is a known part of the travel or temporary-desk workflow. Choose it for that port, then confirm that two USB-A connections are enough and that the laptop exposes the required Alt Mode and Power Delivery capabilities.

Check the laptop before choosing the hub
- Verify DisplayPort Alt Mode on the exact USB-C port. A USB-C-shaped connector does not automatically carry HDMI video.
- Identify the host’s DisplayPort version. The documented 4K 60 Hz paths depend on DP 1.4 Alt Mode; many DP 1.2 hosts are limited to 4K 30 Hz.
- Check USB Power Delivery support and accepted wattage. A 100 W charger label does not guarantee the laptop receives 100 W; Plugable lists up to 92 W to a compatible host and the computer may accept less.
- Count USB-A devices and decide whether Ethernet is real or hypothetical. That simple inventory separates the two models more reliably than their shared port count.
- Measure the 17 cm captive cable route. Make sure the hub can rest on the desk and will not hang from the laptop port.

USB-C travel hub FAQ
Does every USB-C laptop support HDMI through these hubs?
No. The host port must support DisplayPort Alt Mode. USB-C describes the connector shape and does not by itself promise video output.
Will either hub deliver 100 W to the laptop?
Plugable lists up to 100 W input and up to 92 W to a compatible host. The charger, cable, hub, and laptop’s own accepted wattage all affect the actual power path.
Why does the USBC-7IN1 revision matter?
Plugable documents an older revision limited to 4K 30 Hz and revised hardware capable of 4K 60 Hz under stated DP 1.4 host, display, and cable conditions. Confirm the received unit.
Can these replace a full desktop dock?
They are one-display travel adapters with a captive short cable and a compact port set. A permanent desk with multiple displays, more peripherals, or heavier storage traffic should be planned around a full dock and the computer’s supported display routes.
How should I check the buying links?
Read the button or card label: a search can mix revisions and configurations, while an exact-offer card applies only to its named variant and current availability. Confirm the exact SKU, USBC-7IN1 hardware revision, condition, seller, included parts, support, and final checkout price.
Amazon price check: Cards use the named US variant and show a qualifying current USD offer with its check time. Prices expire within one hour; unavailable offers fall back to a labelled Amazon search. Confirm the exact variant, condition, accessories and final checkout price. No numerical Amazon rating is shown because the API did not return usable review data. Price checks do not change the specification-research date.
Research method, primary sources and limitations
We compared Plugable’s US documentation for the exact USBC-7IN1 and USBC-7IN1E models, focusing on port roles, captive cable, display conditions, data connections, power pass-through, and the USBC-7IN1 hardware revision. The advice is editorial interpretation of those published specifications.
We did not test display output, power delivery, Ethernet throughput, USB speed, card performance, heat, cable strain, or compatibility with a particular laptop. Shared USB-C bandwidth and host implementation can affect a real setup.
Correction: The previous article grouped larger docks, compact hubs, and DisplayLink products and presented unsupported test, rank, price, and rating claims. Those claims have been removed. These Plugable models were selected because their documentation establishes exact port roles and host conditions, not because a controlled test proved them superior to every legacy model.
