AI Verdict
This 4.8-ounce travel dock offers 7 ports, including dual 4K display support and 100W PD (with optional adapter), for USB-C laptop users on the go.
This dock is a compact, 4.8-ounce option with 7 ports and dual 4K display capability, making it suitable for travel. However, the inconsistent 4K/60Hz output and the requirement for an optional adapter for full 100W PD make it less universally ideal, especially with its fixed 47 cm cable.
If consistent 4K/60Hz dual display and higher power delivery are critical, look for docks with Thunderbolt 3/4 certification or explicitly verified 4K/60Hz dual display performance and higher native PD.

Pros
- Supports dual 4K displays via DP 1.4 and HDMI 2.0 for extended workspaces.
- Features 7 ports, including one USB-A 3.2 10 Gbps and two USB-C 10 Gbps ports.
- Capable of 100W Power Delivery pass-through to a laptop when connected to an optional 135W USB-C adapter.
- Weighs only 4.8 ounces, making it highly portable for travel.
- Constructed with a chassis containing 66% Post-Consumer Recycled Content.
- Includes an RJ45 port for 10/100/1000M wired Gigabit Ethernet connectivity.
Cons
- 4K display output is often stuck at 30Hz for some users, despite advertised 60Hz capability.
- Achieving 100W Power Delivery requires purchasing a separate 135W USB-C adapter; otherwise, it provides 65W with the included 100W charger (if applicable).
- The integrated USB-C host cable is fixed at 47 cm (18.5 inches), limiting placement flexibility.
- DisplayPort output may not support DP++ (dual-mode), causing issues with passive DP to HDMI cables.
- Some users reported needing to install specific LAN drivers for the RJ45 Ethernet port to function at Gigabit speeds.
Dimension Scores
The plug-and-play setup is convenient, but the fixed cable length and potential driver issues for Ethernet can complicate initial setup for some users.
The integrated 47 cm (18.5 inches) USB-C cable offers no flexibility in length or orientation, and the dock itself has no physical adjustments.
The chassis is made with 66% Post-Consumer Recycled Content, indicating a focus on sustainable and durable materials.
Its 'Eclipse Black' design and minimalist statement with recycled content contribute to a modern and understated look.
Best For
- Remote professionals needing to connect dual external displays to their USB-C laptop.
- Travelers who require a lightweight (4.8 ounces) and compact dock for multiple peripherals.
- Users with USB-C laptops who prioritize products made with 66% post-consumer recycled materials.
- Individuals needing a stable 10/100/1000M wired Ethernet connection on the go.
Not Recommended For
- Users who absolutely require consistent dual 4K/60Hz display output without potential troubleshooting.
- Users needing more than 65W power delivery to their laptop without buying an additional 135W power adapter.
- Users who need a longer or detachable host cable for more flexible desk setups.
Watch Out For
- 4K display output frequently defaults to 30Hz instead of the advertised 60Hz, even with compatible monitors and laptops.
- Achieving 100W Power Delivery requires purchasing a separate 135W USB-C power adapter, as the included 100W charger (if applicable) only provides 65W to the laptop.
- The integrated USB-C host cable is fixed at 47 cm (18.5 inches), which can be too short for some desk configurations.
- The DisplayPort output might not support passive DP to HDMI cables, necessitating active adapters or DP to DP connections.
- Some users experienced issues with the RJ45 Ethernet port not reaching Gigabit speeds until a specific LAN driver was installed.

What Buyers Say
Many users appreciate the dock's compact size and the convenience of having multiple ports for travel, especially the dual 4K display capability. However, a recurring frustration is the inconsistent 4K/60Hz output, with several users reporting being stuck at 30Hz despite the advertised specifications. The power delivery situation also causes confusion, as 100W PD requires an additional purchase, and the integrated cable's length is a common point of contention. Some users also noted needing to install specific LAN drivers for optimal Ethernet performance.
“Man, I bought this thing thinking I'd get dual 4K at 60Hz, but my monitor is stuck at 30Hz, and I had to buy another power brick just to get 100W to my laptop, which is annoying.”
Common Praise
- Compact and lightweight (4.8 ounces) for easy portability.
- Offers 7 ports, including 10 Gbps USB-A and USB-C, for connecting various peripherals.
- Dual display support via DP 1.4 and HDMI 2.0 is useful for expanding screen real estate.
- The 'Always-On' USB port provides continuous power for charging mobile devices.
- Generally plug-and-play for basic functions without requiring driver installation.
Common Complaints
- 4K display output frequently defaults to 30Hz instead of the expected 60Hz.
- 100W Power Delivery requires a separate 135W power adapter, which is not included.
- The integrated USB-C cable is too short (47 cm / 18.5 inches) for many desk setups.
- DisplayPort output has compatibility issues with passive DP to HDMI cables.
- Some users needed to manually install LAN drivers for the Ethernet port to achieve Gigabit speeds.
Ownership Tips
- The actual power delivered to the laptop is often 65W unless a separate 135W adapter is used.
- The integrated cable's length becomes a significant limitation for anything other than placing the dock right next to the laptop.
- You might need to hunt for specific drivers for the Ethernet port to get reliable Gigabit speeds.
- Verify your monitor's refresh rate carefully, as 4K/60Hz isn't always guaranteed.
Frequently Asked Questions
Can this dock power my laptop?
Yes, it supports up to 100W Power Delivery to your laptop, but only with an optional 135W USB-C power adapter. If your model includes a 100W charger, it provides 65W to the laptop.
Does it support dual 4K monitors at 60Hz?
While advertised to support dual 4K@60Hz, some users report it often gets stuck at 4K@30Hz, even with compatible equipment.
What kind of USB ports does it have?
It has one USB-A 3.2 10 Gbps port and two USB-C 10 Gbps ports, one of which is 'Always-On' for charging mobile devices.
Is the host cable detachable?
No, it features an integrated USB-C cable that is 47 cm (18.5 inches) long.
Does it have an Ethernet port?
Yes, it includes an RJ45 port that supports 10/100/1000M network transmission, though some users needed to install a specific LAN driver for optimal performance.
Buying Guide
When looking at a USB-C dock like this, you need to understand what 'Power Delivery' means for your laptop's battery life, how many external screens you can actually run and at what quality, and if the ports match your gear. Don't just assume it'll do everything your laptop's original charger does or that '4K support' means 4K at the smoothest 60Hz. The cable length also matters more than you think for how you'll use it.
USB-C Power Delivery (PD)
This tells you how much power the dock can send to your laptop. If the dock's PD is lower than your laptop's charger, your laptop might charge slowly or even drain battery while connected, like trying to fill a bucket with a slow drip. For this dock, 100W PD is only with an optional, more powerful adapter.
Display Output (DP/HDMI, 4K@60Hz)
This determines how many external monitors you can connect and at what resolution and refresh rate. 4K@60Hz means a sharper, smoother image than 4K@30Hz, which can look choppy, especially when moving windows around. Many users report this dock often defaults to 4K@30Hz.
Port Selection (USB-A, USB-C, Ethernet)
The variety and speed of ports dictate what peripherals you can connect. 10 Gbps USB ports are faster for data transfer (like moving large files) than older 5 Gbps ports, and an Ethernet port gives you a more stable internet connection than Wi-Fi.
Alternatives
If this dock doesn't fit your needs, search for docks with Thunderbolt 3 or 4 for guaranteed 4K/60Hz dual display and higher native power delivery, or look for models with detachable, longer host cables for better desk management.
