Technical documentation identifies the core of the CM219 as the Genesys Logic GL3510 hub controller, a mature USB 3.0 chipset. Performance metrics indicate sustained transfer speeds of 400-440 MB/s on single-port loads, with optimized trace lengths in the 0.5ft lead to minimize signal attenuation. Material analysis confirms the use of a reinforced PVC housing and 30 AWG data/24 AWG power internal wiring for physical durability.
Hardware features include:
- Plug-and-play stability across macOS, Linux, and Windows.
- Four-port USB-A expansion from a single Type-C host port.
- Reinforced strain relief for high flex-fatigue resistance.
Specifications indicate the hub lacks Power Delivery (PD) and relies on the host port's 5V/900mA rail. Technical audits suggest minimal 2.4GHz interference shielding, which may impact wireless peripheral performance when placed near active high-speed data cables.
The Anker 4-Port 5Gbps Hub provides an alternative with a significantly longer 2ft cable for stationary setups. This device is classified as a bus-powered expansion node within the USB-C hubs category.
