Description
A Budget Hub That Won’t Drop Your Hard Drive
The most common complaint about cheap USB hubs? External hard drives disconnecting, failing to spin up, or randomly dropping out. That happens because most budget hubs are bus-powered only — they can’t deliver enough current when you plug in demanding devices.
The H34-J solves this with a DC 5V power input port. Plug in 5V power supply, and the hub gets the extra power it needs to keep all four ports running smoothly. For lightweight peripherals like mice and keyboards, bus power alone works perfectly — the DC input is there when you need it.
What You Get
- 4× USB 3.0 Type-A ports — each capable of 5 Gbps (10× faster than USB 2.0)
- DC 5V external power input — for running power-hungry devices like external HDDs
- Backward compatible with USB 2.0 (480 Mbps) and USB 1.1 (12 Mbps) devices
- Built-in surge protector and LED power indicator
- Ultra compact — 72 × 41 × 11 mm body, smaller than a credit card
- 15cm built-in cable — sits right next to your laptop, minimal desk clutter
