Although many newer cruise ships have more outlets and charging ports available, the ban may come as an inconvenience to travelers who bring along important travel devices, like phones, electric razors, cameras, tablets, e-readers, blow dryers and portable chargers.

When you board a cruise ship your luggage gets scanned for banned items. The list varies slightly by cruise line, but they're looking for obviously outlawed items like guns, knives, and other weapons.

A common workaround for too-few-outlets on Royal Caribbean ships is no longer permitted, as the prohibited items list is now much longer.
