If you’ve lost your netbook charger or you just want a second one for traveling, Kensington is taking preorders on a $50 universal adapter that’s compatible with most major brands. The adapter appears to be about the same size as ordinary netbook power bricks, although it adds a nice USB charging slot for your cell phone and any other USB-powered devices.

Kensington also announced a few more netbook accessories: wired ($15) and wireless ($25) mice, a security lock ($25), and a reversible neoprene sleeve ($15). They’re all available for preorder on Amazon.com and should ship and hit other retailers by the end of the month.
