USB 3.0 Hub — 4 Ports — 5 Gbps

Compact • Bus Powered or DC 5V • Plug & Play • Surge Protection

🔌 Optional External Power — No More Disconnecting Drives

Most cheap USB hubs are bus-powered only — fine for a mouse and keyboard, but external hard drives often disconnect or fail to spin up. This hub has an optional DC 5V power input, so you can connect a power supply for extra power when running demanding devices. Bus powered works perfectly for low-power peripherals.

✅ Key Features

⚡ USB 3.0 — 5 Gbps
10× faster than USB 2.0. Transfer a 1GB file in seconds.

🔌 4 USB-A 3.0 Ports
Mouse, keyboard, flash drive, external HDD — all at once.

🔋 Bus + DC 5V Power
Works from USB power alone, or add a 5V adapter for demanding devices.

📐 Ultra Compact
Just 72 × 41 × 11 mm — smaller than a credit card. Weighs ~76g.
