• This section applies to you if you've ever packed items such as nightlights, shoe horns, portable DVD players, book lights, coffee makers, fire-safety smoke hoods, hotel-door alarm systems, toothbrush sanitizers or electronic language translators, never to actually use them on your trip. The definition of "necessary" varies from one traveler to the next, so it's important to ask yourself if you will reallyneed your ocean-sound machine to get to sleep each night before you stuff it in your bursting suitcase.
  
  Top Tips:
• If you are a travel gadget addict, rotate your collection. Pick one or two that you just have to have and save the others for a future trip.
   
• Keep in mind that some gadgets may call for more room in your luggage than you'd expect; to keep them running, you may need to pack things like spare batteries, chargers or electrical adapters and converters (for overseas travel).
