USB-C Hub Adapter QOLTEC 5-in-1 with USB-C PD 100W, 2x USB-A, HDMI 4K, RJ45

The QOLTEC USB-C Hub Adapter 5-in-1 is a compact connectivity accessory that expands a single USB-C port into multiple useful interfaces: a USB-C PD 100W pass-through charging port, two USB-A ports, an HDMI output capable of up to 4K resolution, and an RJ45 Ethernet port. Designed for laptops, tablets and smartphones with USB-C, this hub supports charging while connected to peripherals, wired network access for stable internet, and an external display for presentations or extended desktop use.

Advantages

This 5-in-1 hub offers simultaneous power delivery and data connections in a small form factor that is easy to carry. The USB-C PD 100W port enables pass-through charging without occupying the main device port, while two USB-A ports accommodate legacy peripherals such as mice, flash drives or external hard drives. HDMI 4K output provides support for high-resolution monitors or projectors, and the RJ45 Ethernet port delivers reliable wired network connectivity for file transfers, streaming and low-latency tasks.

Suitable for

• Extending laptop or tablet connectivity for remote work and office productivity
• Connecting external displays for presentations, meetings or multitasking
• Wired internet access in locations with unstable or restricted Wi-Fi
• Using legacy USB-A peripherals with modern USB-C devices

When it may not be suitable

This hub depends on the host device’s USB-C capabilities; devices that do not support USB-C video output (DisplayPort Alt Mode) will not be able to use the HDMI display function. Similarly, the maximum power delivery is subject to the host and power adapter compatibility, so older or proprietary chargers may not achieve the full 100W pass-through. The compact design prioritizes portability over industrial-grade durability, so heavy mechanical stress or rough handling could reduce its lifespan.

Key specifications

• Ports: USB-C PD (pass-through charging), 2× USB-A, HDMI (up to 4K), RJ45 Ethernet
• Power delivery: up to 100W pass-through (depends on host and power adapter)
• Video output: HDMI supporting up to 4K resolution (host must support DisplayPort Alt Mode)
• Network: Gigabit-capable RJ45 Ethernet (wired connection for stable internet)
• Form factor: compact, portable hub designed for travel and desk use

How to use

Connect the hub to a USB-C port on your laptop, tablet or phone. If you need to charge the host device while using peripherals, connect a compatible USB-C power adapter to the hub’s PD port; charging and peripheral connectivity will operate simultaneously if the host supports pass-through power delivery. Plug an HDMI cable from the hub to an external monitor or projector to extend or mirror the display (ensure the host supports video output over USB-C). Use the USB-A ports for mice, keyboards, flash drives or external storage, and connect an Ethernet cable to the RJ45 port for a wired network connection.

What to consider before purchase

• Confirm your device’s USB-C supports DisplayPort Alt Mode for HDMI output
• Check that your power adapter and host support the desired power delivery level to reach up to 100W
• Verify required network speed and compatibility if you need Gigabit Ethernet performance
• Consider cable lengths and placement on your desk to avoid strain on the host port

Usage recommendations

For reliable video output and charging, use a high-quality USB-C power adapter rated for the required wattage and an HDMI cable certified for 4K. Avoid placing heavy strain on the hub connector and disconnect gently when moving the host device to prolong the adapter’s life.
