Here are some items you may not have thought to pack on a business trip:

1. Back Up Charger(s)

Carry both a plug-in charger and one that operates solely on batteries (like the iGo).

2. Wrinkle-Release Spray

Spray your clothes and let them hang the night before you need them for best results, and be sure to check the care instructions on your garments before use. These sprays work best for casual clothes–if you have a big meeting or need a crisp suit, you’ll still need a steamer or hang them in the shower.

3. Back-Up Travel Documents

Make copies of all of your important travel documents once (license, passport, green card, etc.) and store a set permanently in a pocket of your carry-on. Having copies will save you a lot of time if you lose your identification, particularly when overseas. Leave a set at home, as well.

4. Customer Service Numbers

Keep a set of customer service (airlines, car rental agencies, major hotel chains, etc.) and emergency contact numbers in your wallet (print them on a business card for easiest storage) or in your phone.

5. USB Memory Stick

You can store back-up copies of an important presentation, or you can use it to get copies made easily at your hotel’s business center or at a FedEx Office.
