Innovation isn’t dead among laptops. Check out the Lenovo Power Hub Transformer. It’s a 65-watt transformer for most current ThinkPad laptops. But’s also a 4+1 port USB hub. Four of the USB jacks work like any other USB expansion hub, providing signal and power to devices. The fifth, with white markings on the jack, is always on when the transformer is plugged in, letting you recharge a cellphone or iPod when the laptop itself isn’t on. Brilliant! It’s $75 direct and marginally bulkier and heavier than the standard ThinkPad transformer.
To provide the USB signal, the transformer/hub also plugs into an open USB slot on your notebook, so the net gain is plus-three USB jacks, plus that charging jack.
