Say you want to keep a beverage hot while you work, but you don’t have access to a microwave because you’re on the road. ThinkGeek’s USB Cup Warmer plugs into a Mac’s USB port and warms your mug for 30 minutes, providing heat directly from your computer. This gadget is also great for lazy office workers.—CYRUS FARIVAR

USB Juicer

Do you know Mac users whose cell phones always run out of juice? The Zip-Linq Wireless Phone Charger can restore their gift of gab. It plugs into a Mac’s USB port and includes a 6-volt booster. There are two versions (I and II), so check the lists of compatible phones on the company’s Web site before you buy. For more powering options, you can pair the charger cable with the company’s wall-outlet and car adapters.—TERRI STONE

Keep Cool

While your PowerBook might make you look cool, the Kensington FlyFan actually makes you feel cool. This portable, lightweight fan draws power directly from your laptop’s USB port. The cord is flexible and durable; you can bend it in nearly any direction and it will hold that position. The blades are made of soft nylon, so if you accidentally get caught in them, you won’t get hurt. Now it’ll never be too hot to work outside.—CYRUS FARIVAR
