Coolgear 4 Port USB 3.2 Gen 1 Powered Hub w/ ESD Surge Protection

Our review of the Coolgear 4 Port USB 3.2 Gen 1 Powered Hub finds it aimed squarely at industrial and professional users who need a tough, reliable USB hub that protects connected equipment. The bottom line: buy this if you need a compact, DIN rail or surface mountable hub with true 5Gbps SuperSpeed throughput and per-port 15kV ESD surge protection, because it combines robust electrical protection with a metal chassis and flexible power input options that suit automation, lab, or warehouse deployments.

Key Features

• 15kV ESD protection: Each downstream port includes advanced ESD surge protection to reduce the risk of damage from static or transients to connected peripherals.
• 5Gbps SuperSpeed: USB 3.2 Gen 1 compliance delivers up to 5Gbps data transfer for fast file movement and responsive external devices.
• Backward compatibility: The hub supports USB 2.0 and 1.1 speeds so older devices continue to work without issue.
• Rugged metal chassis: Industrial-grade steel construction and mountable flanges provide secure installation in harsh environments.
• Flexible power input: Wide +7 to 48V DC range and a 2-pin terminal block accept external power adapters for self-powered operation in the field.
• Multiple mounting options: Built-in DIN rail brackets and surface-mount flanges make it adaptable for cabinets, machinery, or workbenches.

Who It's For

This hub is best for system integrators, industrial automation technicians, and IT teams who need a compact, secure USB distribution point in factories, labs, or networked equipment racks. It appeals to anyone who must protect peripherals from ESD events while preserving SuperSpeed data rates.

It is less suited for casual desktop users who only need a simple plug-and-play USB hub without industrial mounting or wide-range DC power input. Consumers who require bundled power adapters or fancy consumer features like charging profiles should look elsewhere.

Pros & Cons

Pros

• Per-port 15kV ESD surge protection offers strong protection for sensitive equipment.
• True 5Gbps USB 3.2 Gen 1 performance with backward compatibility keeps legacy devices working.
• Rugged steel chassis and DIN rail mount make it ideal for industrial installations.
• Wide +7~48V DC input provides flexible powering options in varied environments.

Cons

• Power adapter sold separately, so buyers must source compatible external power for self-powered use.
• No advanced charging features for mobile devices; the focus is data and protection rather than consumer charging.
