Laptops may be convenient, but the heat they produce often makes them uncomfortable to use where their name suggests you should. Enter the cooling tray, which usually comes equipped with a USB-powered fan to keep your legs from getting scorched. Katherine Boehret runs down a few choices in the Wall Street Journal.
- Logitech Cooling Pad N100: the least noisy of the powered pads, "so quiet that it was hard to tell if it was on"—and, at $30, one of the cheapest.
- Microsoft Notebook Cooling Base: also $30, smaller than the Logitech but with a louder fan and more of a drain on the battery.
- Belkin Notebook Cooling Pad: similar to Microsoft's in size, price, and battery drain, but louder still.
- Belkin Laptop Cooling Lounge: at $50, the priciest model, and the loudest, but "I ignored the noise because it was so comfortable." Highly adjustable.
- Kensington LiftOff: at $20, the cheapest model—it has no fan. Very portable, but not as effective at cooling as the others.
