The Lenovo Power Brick may be one of the most useful USB hubs ever conceived. This device combines a laptop's power brick with a USB hub to create a charger that is doubled in usefulness.
Imagine being able to plug in multiple gadgets simply by powering up your computer. The Lenovo Power Brick would make that dream a reality, although it would only be compatible with Lenovo laptops. Hopefully more manufacturers see this idea and make it standard on all laptop chargers someday soon.
