UGREEN CM481 (90307) 7-Port USB 3.0Hub

UGREEN CM481 (90307) 7-Port USB 3.0 Hub

If your laptop or desktop keeps running out of USB ports, the UGREEN CM481 (90307) 7-Port USB 3.0Hub solves it cleanly. This 7-port, externally powered USB 3.0 hub maintains high transfer speeds while powering multiple peripherals at once. Unlike basic splitters, it features per-port switches to quickly isolate a device (e.g., an external drive) and BC 1.2 smart charging on four ports to top up phones, earbuds, or accessories when you need it. The DC 12V input ensures consistent voltage to every port—important for bus-hungry devices like mechanical keyboards, USB microphones, capture sticks, and portable HDD

Who It’s For

Creators & streamers: Run webcams, mics, lights, capture cards, and storage without random drop-outs.

Office & remote work: Keep dongles, receivers, printers, and smart card readers always connected.

Students & power users: One cable to your laptop; flip port switches instead of plugging/unplugging.

IT & labs: Stable, powered expansion for testing multiple USB devices simultaneousl

Real-World Performance Tips

For external drives/SSD enclosures: Use a short, quality cable and a USB 3.0 port on the hub for best speeds.

For bus-power devices: Keep the DC adapter plugged in so all ports receive stable current.

Charging + Data: Use the charging-capable ports (#4–#7) when you want to top up a phone while still mounting storage on the other ports.

Hot-swap safely: Power a port off first, then disconnect sensitive devices like storage.

Compatibility & Setup

1. Plug the 12V adapter into the hub.

2. Connect the USB-C host cable to your laptop/PC.

3. Add your devices. If a device isn’t recognized, toggle its port switch or move it to a different port.

4. No drivers required for standard devices on Windows/macOS/Linux.

Compared to Cheaper Unpowered Hubs

Voltage stability: Unpowered hubs share limited bus power; CM481’s 12V/2A input keeps devices happy.

Port control: Most basic hubs lack individual switches and charging support.

Longevity: Better for permanent desktop setups with multiple always-on peripherals.
