Portable Power Bank
As a sign of the times, none of the gadgets featured thus far require archaic disposable batteries.
But they do all depend on an electric outlet now and then.
To reduce the number of outlets and cords required (not to mention how often you’ll need to pull over to recharge), a portable power bank could come in handy. You shouldn’t have to spend much on one of these, and most options aren’t much larger than a Swiss Army knife. Try to find one sporting a 3-in-1 adapter cable so that you can charge standard USB-equipped devices alongside old and new iOS products.
Plug and Play
When traveling far from home, there are a few techie odds and ends you should just always have stashed in your bag and ready to go so you don’t have to think twice about them later.
I’d start with a standard USB charger — if you didn’t consider the slide before this. (If you have a lot of gadgets, you’re bound to have an extra one of these floating around.)
Depending on how long of a trip you're about to embark on, a single universal plug adapter for international travel along with a two-prong headphone adapter are easy to toss in a bag and can be lifesavers later. Many airplanes are still outfitted with two-prong headphone jacks for some reason, and usually the only headphones that work with these are the ones the airlines will supply you with — sometimes for free and sometimes for a fee. To take advantage of the higher quality headset you already packed, have this tiny plug in your bag just in case.
It wasn’t until I was traveling abroad with friends from around the world toting a multitude of different smartphones that I truly grasped the value of Whatsapp. OK, so maybe the soon-to-be-Facebook-owned isn’t worth $16-19 billion, but the value proposition is undeniable.
Never before has an app felt so intuitive and just MADE SENSE until put into practice. You can communicate with basically anyone else who has a smartphone and this app so long as you have a wifi connection — incredibly helpful when you’re on a wifi network at 30,000 feet or in another country and you don’t want to pay for international service.
This app also solves the age-old problem of group photos when everyone wants the helpless photographer to take the same snapshot with each and every person’s camera. Just use Whatsapp and you can send the photo (scratch that, as many photos as you want) to everyone in the group in a second.
WhatsApp Messenger: Free for messaging over wifi; standard data rates apply otherwise. Available for iPhone, BlackBerry, Android, Windows Phone and Nokia.
