On the recommendation of my colleague Gary Leff, I now carry a Monster MP OTG400 BK Outlets To Go Power Strip. Why? Hotels, airports and especially cruises often only have one or two outlets, and that’s just not enough to charge all of my devices. And if my wife is with me, “Fuhgeddaboudit,” since she always has three devices (iPhone, iPad and computer) going at once. This travel power strip only costs $11 on Amazon, has 4 AC outlets and is ultra-compact so it can fit into luggage and briefcases (dimensions: 6.25″ x 2.25″ x 1.8″).
