Power Outlets on Cruise Ships

Steve asks:

What type of power outlets are in a crew cabin on an international ship? Are they US, EU, UK or does it depend on where the ship is registered? I am wondering whether to get an international converter for my laptop and phone.

Both passenger and crew rooms are typically equipped with both 115V and 230V outlets. Here are 2 pictures of two of the outlets in my current passenger cabin.

Since cruise ships are often moved from one part of the world to another several times within the same year, and can even change their port registry several times over their years of use, I think this dual-outlet thing is probably normal on all ships. I’ve seen it on both ships that I’ve been on.

I would recommend bringing, or planning to buy, a power strip on the gig.  Cabins usually only have a few outlets in each cabin, and they need to be shared by all roommates.  I don’t know what ship fire code dictates, but I know if you look at the pictures of my old crew cabin, you’ll see we had a power strip under the desk.
