USB C Splitter with 4K@60Hz Video Output - 5-in-1 USB C Hub

In this review the ACASIS USB C Splitter is presented as a compact way to turn a single Thunderbolt 3/4 or USB C port into a small mobile workstation. The bottom line: it is best for users who need a single high-resolution display output plus fast data lanes and pass-through power without carrying a larger dock. The review focuses on real-world use with portable monitors, NVMe enclosures and laptop charging, and highlights that the adapter requires a host port supporting Power Delivery, DisplayPort alt mode and data transfer to realize its full feature set.

Key Features

• 5-in-1 expansion: Converts one USB C or Thunderbolt port into a 4K@60Hz video output, three 10Gbps USB C ports, one 10Gbps USB A port and a PD charging input to simplify a mobile setup.
• 4K@60Hz video output: The dedicated USB C video port supports DisplayPort alt mode for sharp output to portable USB-C monitors and displays at up to 4K@60Hz.
• High-speed data lanes: Three USB C 3.1 ports and one USB A 3.1 port deliver up to 10Gbps bandwidth for fast transfers with SSDs, phones and tablets.
• Pass-through charging: The PD input supports up to 100W on the hub and up to 85W pass-through to power most laptops while peripherals are connected.
• Portable workflow: Small form factor makes it easy to add a monitor, external drives and power when working from a hotel, office or home desk.

Who It's For

The ACASIS hub is aimed at professionals who carry a single USB C or Thunderbolt port laptop and need one reliable video output plus multiple high-speed ports for storage and accessories. It is a good fit for presenters using portable monitors, content creators who move large files to external SSDs, and anyone wanting to charge their laptop while using peripherals.

It is not ideal for users who need multiple independent external displays, legacy VGA or Ethernet ports built in, or those with laptops that lack DisplayPort alt mode or Power Delivery on the USB C port; those users should look at a larger docking station with more varied I O.

Pros & Cons

Pros

• Combines a single 4K@60Hz video output with several 10Gbps data ports in a compact dongle.
• Three USB C 3.1 ports and one USB A 3.1 port provide versatile, high-speed connections for drives and devices.
• PD pass-through up to 85W lets users power a laptop while maintaining stable data transfers and display output.

Cons

• Requires a laptop USB C or Thunderbolt port that supports Power Delivery and DisplayPort alt mode, so compatibility must be confirmed before purchase.
• No built-in Ethernet or multiple independent monitor outputs, limiting use for complex multi-display or wired-network setups.
