Travel Tip: Pack a portable power strip with your computer

If you travel by air on business, you've probably spent more time than you want to think about working on your laptop in airports. But what happens when the airport is crowded, every electrical outlet is in use, and your battery runs out of juice?

A portable power strip can solve the problem by letting multiple users plug into the same outlet. The portable models are compact, easy to pack, and run about $20. They also come in handy in hotels, especially older ones with an insufficient number of power outlets.
