USB hubs come in two types: powered (wall adapter) and unpowered (bus-powered from laptop).

I tested both to show you when you need external power.

The Difference

Unpowered hub:

• Powered by laptop USB port
• Limited power (~2.5W per port)
• Cheaper, more portable

Powered hub:

• External power adapter
• More power per port (~7.5W+)
• Can charge tablets, external drives

When You Need Powered USB Hubs

✅ Get powered hub if connecting:

• External hard drives (especially 2+)
• Charging tablets
• High-power USB devices
• 4+ devices simultaneously

✅ Unpowered is fine for:

• Mouse + keyboard
• USB flash drives
• Webcam
• 2-3 low-power devices
