The Kensington Notebook Universal DC Power Adapter comes in different flavors (120 Watt, 70 Watt, 30 Watt) and packs a lot of power:
It it a lot slimmer than the standard power supply that comes with most laptops as it is just slightly larger than my external 3 1/2 external HD. But the really cool features are all the things that you do not get with a standard power supply:
- it can charge a wide range of devices (including laptops, phones, PDAs, iPods, …) using SmartTips
- it charges several devices at the same time
- it lets you charge from a wall outlet as well as power outlets in cars and air plane
