Are "power strips" allowed??
My wife has a CPAP machine and we borrowed and extension cord from Guest Services on our last card. You need to make sure you turn it in before disembarking or be charged a $50 fee. Last cruise was actually a B2B, so I needed to do this twice, since they close out there books after each cruise.I think that you can request an extension cord on the cruise ship and they let you use one for your cruise. My Mom has a CPAP machine and I am pretty sure that is what she used. Anyone know?
They are approvedDo you remember if there was anything special about their approved extension cord?
I know that extension cords are prohibited. But is this not an extension cord (technically)?

OK, it doesn't have a "cord", like this

But why isn't it the same?

Most of what I generally need to charge are things that have a USB port on one end. So I use a multicharger like the one below. It plugs directly into the wall so it's not an extension cord in anyway so if you have a lot of products that require charging it may be a good compromise. If the taps aren't allowed.

I researched this product for a Carnival forum thread, and found that it is in fact surge protected. There are very few USB ports that are not surge protected, and it takes some research to the manufacturer's website, or even contacting them to be sure. The only one I have found that is guaranteed not to have a surge protector is the Zilu 4 port hub. This information was received directly from Zilu, and was informed that all of their other products weresurge protected. Unfortunately, buying online does not allow checking the packaging or the fine print on the device, so the buyer should be wary.
http://boards.cruisecritic.com/showpost.php?p=49476307&postcount=65Well, there is the USCG Safety Notice, and the NFPA UL 1449. The USCG Safety Notice is written about two fires on cargo ships, but you'll just have to take my word for it that there is no difference between the wiring of a cruise ship or a cargo ship. The grounding systems are the same, because they both face the same problem when you introduce stray electrical current into the steel hull in sea water: electrolysis. NFPA UL 1449, if you buy a copy of it, lists the additional protective devices required in a surge protector when used in impedence grounded systems, which while not called out specifically as marine, that is what they are. The post by cavediving that is referenced in post #7 has descriptions of the problems caused when using surge protectors onboard ships by a professor of marine engineering at Texas A&M. Not sure what more I can give, and I don't know that there has been a documented case of this kind of fire on a cruise ship, but the lines' insurance companies are interested enough to require the recent changes in policy.
I feel strongly enough about this, that I have researched a lot of products, not only on consumer websites, but the manufacturer's websites, and have even gone to e-mailing the manufacturer if I cannot get definitive answers. Two products I have found that are not surge protected are:
The above referenced uber product, I am not sure of any other uber product, but this specific one is fine.
Zilu 5 USB port hub. This, and this one only, from Zilu is not surge protected. http://www.amazon.com/dp/B00V33RCTU
Just about any power strip (outlets only) from Home Depot, Walmart, etc., in the $3-5 range (including one from Belkin) are fine.
This Monster brand power strip is okay: http://www.amazon.com/Monster-MP-OTG...ds=power+strip
Powercube-usa has a product that is multi-outlet and multi-USB, without a surge protector, but it doesn't get very good ratings for sturdiness.
I checked the manufacturer's site on this: http://amzn.com/B003TXRTNG, it is okay.
I make no recommendation as to any of the above products performance (sturdiness, usability, convenience, etc.), as I have never actually used any of them (except the Home Depot $3 power strip).
I've answered on several threads over the last couple months about this, and if you search those threads (via my posts), you'll see many products that I've researched that are in fact surge protected when not obviously advertised as such.

Well, thank you. But the reason I have answers is because I ask questions. I try to learn something new every day.The world is real & round after all. After having so many questions answered by PrincessShmoo, I am at a loss that she had a question. She has had an answer for so many of us. It is hard to believe the all-knowing and all-wonderful PrincessShmoo is human after all...
Thank you Shmoo for all your advise, keep it up.

Technically powerstrips are allowed, it's surge suppressers that are not allowed, so a powerstrip without surge suppression is not a problem.
But as in my reply to PS above, without inspecting everyones powerstrip, the dcl cannot tell.
- Extension cords or surge protectors
FigmentSpark is correct in their interpretation of what the chief engineer was saying.
And the loaner extension cords are inspected and made of heavy duty, high quality cable and are suited to being put under maximum load without burning up
Yes, technically and taken in the literal sense, it could be defined as an extension cord. However if you read the chiefs posts, it isn't so much about cord on the power strip, but ones that have surge protectors that cause a problem on ships specifically.Technically, a power strip *is* an extension cord. It just has several plugs at the end of the extension cord.
