If your laptop charging adapter is too bulky and heavy, look at Targus’ new APM69US “Premium Laptop Charger” that is half the size and weight of typical AD/DC chargers and is about the size of a Blackberry.
The APM69US is said to be the smallest adapter on the market. It comes with nine laptop tips fitting notebooks from most brands, one mini-USB tip for devices like cellphone, camera and one iPod/iPhone tip. For added convenience the charger plugs directly into the wall and the AC prongs rotate 180 degrees, allowing the user to plug the charger into a power strip without blocking other outlets.
The Targus APM69US is now available for $137.48.
