Have you ever gone out of town with your cell phone and forgotten your charger? Brought your camera but missing the battery - or left the card in your home computer? Missing the cable to connect to high speed and have to buy one because the hotel doesn't supply it? Brought along accessories that you don't use that took up space and added weight?
The answer is to make a checklist and to USE it.
List all the things you MIGHT want to take: for me that includes
- Laptop
- Air card
- Internet connection cable
- Charger
- Electric plug-in
- Squid (to expand the number of outlets)
- Bose earphones for the plane
- iPhone
- iPhone charger
- Konika pocket digital camera
- Konika battery charger
- Canon digital camera
- Canon battery charger
- Extra media card
- Media card reader
Save the basic template, then print out a few before every trip. Check off everything when you're packing to go (put a N/A if you've decided not to take something). Use the blank ones for when you're packing for the next leg or returning home.
Make separate checklists or a longer checklist for things like business cards, itinerary, tickets or boarding pass, drink tickets, passport, reservation confirmations, presentation materials, handouts, etc.
One for clothes and accessories.
What items to you have on your Tech Travel Checklist that I haven't mentioned above?

I have a special travel bag that contains the things I need. Any cords, chargers, adapters, etc. are always in there.
I certainly need to do a better job of this. I am fine with the clothes, but on the tech end I always forget something. Thanks for the list, Sharon.

A checklist makes perfect sense, it is not pleasant arriving at your destination only to discover you left an important tool.
Sounds like a good plan to me. I try to keep extra batteries and etc. in my computer case. A list there makes sense. Thanks.
Leon - that makes things very easy. No need to pack - or unpack.
Jeff - me, too. I need to not just have them, but consistently use them.
Maria - that does present a problem.
Linda - old dogs can learn new tricks
Barbara Jo - you're ahead of the game
William - that IS a great place to keep the checklist. I've taken photos of the luggage itself, but haven't been organized enough to photograph the contents. Good idea.
Dale - great advice. Most of us wouldn't think about that.
Joe - I doubt that you'd forget your golf clubs, checklist or not.
Jennifer - Right.
Cynthia - it might also be good to write down the various types of batteries needed.
