Description

Ugreen UG- 20841 USB-C to 4*USB 3.0 Hub

The UGREEN UG-20841 functions as a USB Type-C expansion hub that transforms a single USB-C port into four USB 3.0 Type-A ports. This hub addresses port scarcity on modern ultrabooks, tablets, and laptops that feature limited USB connectivity.

USB 3.0 Data Transfer Performance

The UG-20841 implements USB 3.0 (also designated as USB 3.1 Gen 1) technology across all four downstream ports. Consequently, each port delivers theoretical bandwidth up to 5 Gbps, which translates to practical transfer speeds approaching 500 MB/s under optimal conditions. This represents a 10x improvement over USB 2.0’s 480 Mbps maximum throughput.

Furthermore, the hub supports simultaneous data transfers across multiple ports. The 5 Gbps bandwidth is shared among active devices, meaning total throughput divides according to current usage patterns. For example, transferring data on two ports simultaneously allocates approximately 2.5 Gbps to each active connection.

Individual Port Power Switching

Each of the four USB 3.0 ports on the UGREEN UG-20841 provides up to 900mA of power per port, adhering to USB 3.0 power delivery specifications. This capacity accommodates most bus-powered peripherals including external hard drives, flash drives, keyboards, mice, and webcams without requiring external power sources.

The hub incorporates intelligent power management that distributes available current efficiently across connected devices. However, power-hungry peripherals such as external DVD drives or portable monitors may require supplemental power through dedicated adapters.

Backward Compatibility Architecture

The UG-20841 maintains full backward compatibility with USB 2.0 and USB 1.1 devices. Older peripherals function normally when connected to the hub’s USB 3.0 ports, though they operate at their native speeds rather than USB 3.0 rates. This compatibility ensures legacy devices remain functional without requiring separate USB 2.0 hubs.

Additionally, the hub negotiates connection speeds automatically. When USB 2.0 devices connect, the specific port adjusts to USB 2.0 signaling while other ports maintain USB 3.0 capability for SuperSpeed devices.

Plug-and-Play Operation

The UGREEN UG-20841 operates without driver installation on major operating systems. Upon connection, the host device recognizes the hub immediately and activates all four ports. This driver-free functionality simplifies deployment and eliminates software compatibility concerns.

The hub draws power exclusively from the USB-C host port, eliminating external power adapter requirements for the hub itself. This bus-powered design enhances portability and reduces cable management complexity in mobile work environments.

Physical Construction and Design

The UG-20841 features a compact aluminum alloy chassis measuring approximately 98mm × 34mm × 16mm. This slim profile makes the hub suitable for travel alongside laptops and tablets. The aluminum construction provides several functional advantages:

  • Superior heat dissipation during sustained high-bandwidth transfers
  • Structural rigidity protecting internal circuitry from physical impact
  • EMI (Electromagnetic Interference) shielding that prevents signal degradation
  • Premium aesthetic matching modern laptop designs

Moreover, the hub includes a braided USB-C cable approximately 15cm in length. The integrated cable design prevents separation from the hub body, while the braided exterior provides abrasion resistance and tangle prevention.

LED Activity Indicators

An integrated blue LED indicator illuminates when the hub receives power from the host device. This visual feedback confirms proper connection and active status. The LED remains continuously lit during operation, providing immediate verification of hub functionality.

USB-C Host Connection

The UG-20841 connects to host devices via USB Type-C connector. The USB-C interface provides reversible plug orientation, eliminating insertion direction concerns. The hub supports both standard USB-C ports and Thunderbolt 3/4 ports, though it operates at USB 3.0 speeds regardless of host capabilities.

It’s important to note that the hub requires USB-C ports with data transfer capability. Some USB-C ports on devices serve exclusively for charging and lack data functionality. Therefore, users should verify their USB-C port supports data before expecting hub operation.

Multi-Device Connectivity Scenarios

The four-port configuration accommodates various peripheral combinations simultaneously:

  • External mouse and keyboard plus two storage devices
  • Wired network adapter, flash drive, smartphone charging cable, and printer
  • Multiple flash drives for data transfers between storage media
  • Card readers, security keys, and other authentication devices

Each connected device operates independently without requiring users to disconnect and reconnect peripherals when switching tasks.

Chipset Technology

The UGREEN UG-20841 utilizes a VL812 chipset from VIA Labs. This proven controller IC manages USB traffic distribution across the four downstream ports while maintaining USB 3.0 specification compliance. The VL812 chipset provides:
