Yes they do. I'm thinking of getting one of these.

Those 2 listed above will draw 3.3A and 5A respectivley, that isnt going to run to long before taking a good chunk of charge out of the average boaters batteries unless your on shore power or have a good collection of solar / wind charging.

how many hours were you planning on running them for, and can your batteries keep up?

I bought a similar one last year and wonder why I bothered. The maximum extraction is no where near the quoted - about a quarter of that rate. The trouble is when the air is cold the peltier unit struggles to get anything out, so you spend a fortune in leccy warming the air so the unit can work, but that warm moist air then finds nice cold bits of the boat to condense in and cause damp /forums/images/graemlins/frown.gif and on 12volts they use shed loads of battery power for very little effect.

Much better is a desciator (?) unit as even our old compressor unit is constantly switching to defrost when it gets really cold. They use 500W but only need to come on very infrequently as they are very efficient. Next yaers budget for me though.

Thats a lot of power to remove such a small amount of water.

I needed a full size dehumidifier a few weeks ago and ended up buying from Focus DIY store. They also had the little 12v version in Cliff's link above. Bought one on impulse for £19.99 and it's been very good in my 24ft boat. I wouldn't try to run from the battery as drain would be too much. The main attraction to me was its size.
At the boat show last weekend I saw Nauticalia selling the same model for £49.99!!
