One of the things I love about the Asus Eee PC 1000H is that I can get about 5 hours of battery life from a single charge of its 6 cell battery. But if you’re saddled with a netbook or laptop with a smaller battery, you might be lucky to get 2 or 3 hours of use. And that means you probably have to carry a power brick and cable with you when you leave the house, which can add almost a pound to the weight of some laptops.
Julie over at The Gadgeteer discovered an interesting solution with the help of the folks at the MSI Wind forums. You can pick up a small plug adapter for $3 from Stayonline.com and plug it directly into your power brick. While you still have to carry the power brick with you, you can leave the cord that runs from the power adapter to the wall socket at home and just use the plug adapter to plug the brick into a wall socket. That shaved a total of 4 ounces off of Julie’s power supply.
The plug adaptor may work with other laptop power supplies as well. Make sure to check the voltage before trying it with another device.
