Lenovo 90W Slim AC/DC Combo Adapter

Slim laptops are in vogue.  Unfortunately, many are accompanied by power supplies that seemingly rival them in weight.  Some refer to them as “bricks.”  Lenovo, the maker of the ThinkPad line of laptop computers, recently introduced a combination power supply that rivals the company’s ThinkPads in design and sleekness.  The Lenovo Combo adapter weighs under a pound and is only 0.61” high by 5.65” long by 3.07” wide, making it ideal for the business traveler intent on keeping off weight.  In testing, I found it more convenient to use on an airplane than the brick I used to carry, which was almost double the size.

In addition to powering ThinkPad and IdeaPad computers, it can power most mobile phones, PDAs, and portable music players via optional connector tips.  An optional dual-charging cable allows more than one device at a time to be charged.

It’s $119 at Lenovo.com.
