The Kensington Wall Laptop Power Adapter ($69.99) provides 90 watts of power, but is still rather small, measuring 5.18-inches long, 2.04-inches wide, and just 1.12-inches tall. Weighing in at 11.3-ounces, this adapter is also energy efficient, with an Energy Star rating that lets you know it uses 30 percent less energy than traditional laptop power adapters. It's compatible with laptops from all of major manufacturers, including Acer, Asus, Dell, HP, IBM, Lenovo, Sony, and Toshiba.
If you use multiple mobile devices on the go, or can't spare one of the USB ports on your laptop to charge your mobile phone or iPod, you can choose the second model, which also includes a USB power port. It comes with a $10 premium on the price for the base model, but you never know when you're going to need an extra USB charging port.
Both of the new power adapters are now available for pre-order from Kensington and from Amazon.com. Each one carries a two year limited warranty, and will start shipping out during the first week of September.
