The T3Hub is probably the world’s smallest USB hub. About as big as the size of a USB key, it expands a single USB port in to an additional 3 ports. Also, the T3Hub is a self-powered hub, meaning it can accept devices with a nominal power requirement of 500 mA. Amazingly enough, it can also host two normal low-power USB devices with one high-power USB device without requiring a power supply for itself. And because of its diminutive size, the T3Hub is perfect for laptops. Dr. Bott’s T3Hub retails for $19.99.
