Next to my always-packed ready-to-toss-into-a-suitcase toiletry bag is another, more essential, sack 'o goodies – a pre-packed ready-to-toss-into-a-suitcase gadget travel case. Shampoo and razors can easily be replaced upon arrival, but these are the top gadgets you shouldn't be on the road without.
You might want to charge your gadgets during long drives, which makes this compact, multi-USB jack charger really handy. You plug the full-sized USB jack into one of the two USB jacks on the cigarette lighter plug, and either or both the micro and mini USB jacks into almost any portable gadget extant other Apple gear for charging. The jacks can be extended thanks to a pull-out spring-loaded extension cable. I picked this up in Europe a few months ago, and it's due in the U.S. sometime next month at a price-to-be-determined.
