One of the most important things we have learned over the years is you really need to protect items connected to the electrical system on a cruise ship. Items such as camera chargers, laptops, tablets, readers, ipads/ipods, MP3 players, portable hard drives etc., need to be protected from high voltage power surges. We lost a laptop on our first World Cruise because of this and we were on another cruise when the Internet Cafe lost all of their PCs because of a massive power surge. An easy and inexpensive way to protect your sensitive high tech items is by using a state-of-the-art surge protector. When traveling, we always have our Belkin Mini Surge Protector with us.

There are two models of this surge protector. One rated at 5 watts and one at 10 watts. Each unit has two USB charging outlets and three 120V outlets for charging. Both are rated at 918 joules to help handle voltage fluctuations, energy spikes, and surges. Its prong power rotates 360 degrees so it can fit into almost any location. The best part is that one model is $10 and the other is $19. Each are available locally or through companies like Amazon.
