Looking for a way to run a real hair dryer on the boat.  If we hooked an inverter up to the battery would that work?  Thanks!

Welcome Freedom,

Yes, it will work just fine. Get an inverter larger than the load. Although the load is for the most part resistive, there is the motor to consider.

Don't place the inverter in the engine compartment, use adequate wire size to run it, and protect it with a circuit breaker or fuse, marine type, of course. Google Blue Sea for appropriate equipment.

Ask more questions.

And keep in mind that a typical hair dryer will suck 180 amps from the
battery on high heat. Yes, 180, which is a HUGE HUGE load! To do this
properly you need a bank of at least four standard 110ah deep cycle
batteries.

So the answer is you can do it, but you will need huge expensive wires, a big
inverter, and huge batteries.

Swamp brings up a good point, it is power hungry!

I've successfully used a dryer when camping. My 2000 watt inverter came with heavy clip leads that I attached to our pickup battery. The whole family used a 1200 watt travel dryer without a problem.

The truck was running. The truck has a 120 amp alternator.

It is doable without a large battery bank provided you're no trying to run an 1875 watt dryer with no other source on the line. Keep in mind that even though my truck has a high capacity alternator, it was a loosing battle at idle. However, I wasn't too concerned as just left the truck running while we picked up and left.

In general, things that create heat are going to draw hard on your batteries.

When I'm on the hook I tend to use batteries and inverters for things that don't.  TV's, computers, refrigerators etc.

For things that generate heat (water heaters, hot plates, coffee makers etc.) I tend to rely on my little red thingy.

 As mentioned, a hair dryer will draw a high amount of current. About the only good thing in trying to do that is that the hair dryer will only need to be run a few minutes.

 I have a 2500 watt inverter and four group 29 batteries attached to it. Running a 1500 watt hair dryer for five minutes will draw about 12-15 amp hours from the battery bank. That's not a big deal considering my bank is 420 amp hours (210 amp hours at 50% drain).

 Trying to run such a large load on one or even two small batteries is going to be tough, if not impossible. Drawing that much current (140-160 amps @ 12v) will drop the voltage of the batteries and will cause the inverter to shut down assuming your inverter has low voltage protection.

Thanks so much for ALL the responses! :)  Looks like the hair dryer won't really work out with our current set up however my hubby DOES have the EU 2000 and I totally forgot about that (Ibought it for him 2 christmases ago!).  I don't know if he'll want to lug it around on the boat but at least it's an option.  Thanks!

I'm not sure how to phrase this so you don't think I'm just being an ass,
but...why would you use a hair dryer on the boat? This isn't a formal event.
There's no need for makeup and made-up hair. Enjoy the casual time.

Its not possible to attain Brigitte Bardot's St. Tropez look without a decent blowdryer and 110v.

Don't know if any of you saw the Friends episode when Monica's hair frizzed out but that's what my hair looks like if I don't blow dry it.  As long as it doesn't get too wet, it's ok and I can deal and just go. but if it gets completely wet combined with the wind from the boat, there may not be room for guests along with my hair.  It's not all one length so not even a pony tail will contain it! :(  I was also interested in this for days when we stay out overnight or 2 or if we have guests with us who stay and may want to blow dry. I can go a day without washing my hair but after that, it's not pretty.

12v heating devices simply do not work. WATTS is what you need to
generate heat, and I don't care how you get there, the formula for volts and
amps to watts is a constant. Energy is watts. Heat is energy. You need 'x'
amount of energy to achieve a certain job, simple as that.

The "wiffy"?

I'd think generally the generator is the way to go. If you don't have one on board, convince your hubby to take the Honda  onboard.  Either convince him that the coffee will be better or that you can do Frozen Margaritas better if you have a 110v blender!

Inverters.

We have a 600W inveter with surge to 1000. Our travel hair dryer has 2 heat levels: 1200 and 600. The admiral uses the 600W setting with the inverter, and it works fine.\

We also bought a 600W 5 cup coffee pot for when we are in the no-wake zones and its cool/cold out (Thats under 65*)

However, inverters are not as simple to install and use as it would seem.

 

Lets use a 2000W, inverter as an example, for maybe a microwave and/or a hair dryer.

The current drawn from the batteries with a 1200W load is roughly 120 amps. If the inverter is 4' or > from the battery, I would use 2/0 or 3/0 wiring at about $3/foot.

Then, to safely put out 120 amps, even for 10 minutes, you would need a couple of 220 AH golf cart batteries (minimum). Bigger is better. BTW, my Sams GC batteries weigh about 72# each.

Now, you got to recharge the batteries. You will beed a minimum of a 20 amp smart or 3 stage charger.

So, with all that is done, you have about 200# of hardware aboard.

Cost?

Inverter (marine) 2 KW, 2-300$

Batteries @ 70 each         &n bsp; 150

Charger          ;           ;           ; 300

Misc (wire, trminals, mounting stuff

                                              100

               est total                $850   and  thats only  if you do the work yourself (and only do so if qualified)

 

Now for about the same money, get a Honda 2000. Weight 50# (you save 150#)

And it will run your stove, air conditioner, heater, battery charger, TV, etc , etc., but  not at the same time.

Having a generator PLUS an inverter is the ultimate way to go. Our boat
had a built-in generator and I added a 2k inverter. In the evenings we'll
often fire up the TV in the cockpit and stream videos from the iPads or
laptops, all run from the inverter. I monitor the battery bank with a
Xantrex Link Pro; if we looking a little low I give the bank a 20-30 minute
recharge with the generator. We've got a 60a charger, so 30 minutes puts
30 amp-hours back into the bank.

In the morning I fire up the generator to make coffee and put a bit of
power back into the bank. Same thing, about 30 minutes. If I feel like
making an extra shot of coffee later in the morning I typically just run that
off the inverter, even though it's a high load, it is only for a very short
time.

I have a gen and a large inverter as well the truth is I have never used the inverter although the ice maker may pull from it if I don't have the gen on but this is rare.  I like having A/C the extra gallon an hour is not a big deal in the overall scope of things.

Power on a boat a float. Time honored problem, until now.

I use several Honda products. For my 27.5’ Bayliner Ceirra Sunbridge, the EU2000i does the job day or night. Just pay mind that whatever generator you use, make sure you have CO2 detectors installed everywhere you have enclosesd areas. Always place the generator so that it is downwind from your vessel. Pay mind that boats will swing in the wind and with changing tide and water currents. With that change comes the potential for blow-back of exhaust into your vessel. Perhaps through open windows and doors –even such with bad seals. I keep a EU2000i as a back up on all 4 of my vessels. They came in handy once or twice given the battery boost output available on Honda generators. I can’t tolerate the diesel exhaust that spews from the big gens on my 72’. The fact that these gens are gas appeals to me. The power adjust idles make for very efficient running costs. Even with little draw on the diesel twins, they consume a minimum amount of fuel that really adds up fast.

Honda EU2000i
•     2000 watts, 120V
•     Ideal for TV/DVD, satellite, fridge, coffee pot, and more
•     Super quiet
•     Easy to carry - less than 47 lbs!!
•     Fuel efficient - up to 9.6 hrs on 1 gal of gas
•     Inverter - stable power for computers and more
Honda EU2000i Companion –for a few extra bucks you get more just in case of those unknowns
•     2000 watts, 120V
•     Built in 30A outlet for easy parallel capability with another EU2000i
•     Ideal for TV/DVD, satellite, fridge, coffee pot, and more

•     Great for RV applications
•     Super quiet
•     Inverter - stable power for computers and more

Honda EU3000i Handi
•     3000 watts, 120V
•     The lightest 3000-watt inverter generator we’ve ever made

•     Wheels and folding handle for true portability
•     Compact design
•     Offset handles for easier lifting
•     Super quiet

I use the EU3000i to power all my 27 company 48 foot featherlite mobile marketing trailers (includes RV top AC/heater units). Never had an issue –got to love the two year anywhere in the USA warranty.
Just look at the gas consumption - up to 9.6 hrs on 1 gal of gas – up to 14 hours on minimal draw.
You can also haul these light-weight units ashore for camping, beach picnics, and whatever! No, just in case you are wondering, I’m not affiliated with the sale of any Honda product. I use them. They work for me without fault. Thought I’d chime in.

Good luck.

Of course not. It's the noise and CO that most object to, and the reason we
don't run ours a lot.

Hard to believe anything that heats would only draw that amount, but if the case then you should be fine.  Just watch, because something hot like that lying around on a boat that rocks isn't a good thing.

did you see review of 12-volt hair dryer?  don't get me wrong, i appreciate you adding it to the discussion, but product doesn't look encouraging...  i think i keep trying to get her to embrace the lifestyle and in the meantime i'll let her try her iron for a few minutes...

The downside to 12v items that need to producea lot of heat such as a hair dryer or coffee maker is the current they need to draw to make them 'useful'.

I did like this part of the person who gave a review "I'm bald but wouldn't dry my hair in 15 minutes". Sure hope he didn't get the 12v pizza oven.

I hate to throw cold water (forgive the pun) on your plan
but using a portable generator on a boat is a bad idea.
Those were never designed to be used on boats and are not
"marine" generators. They can result (as was mentioned)
in carbon Monoxide, and can present a shock hazard. I
sympathize with your hair problem but really, would you
rather be poisoned or electrocuted? I know this will
start a large argument, but I have cautioned against
portable Gensets on boats for many years.

Proper use of a portable generator is very safe. In some ways even safer than a permently mounted marine generator. Prior to starting a portable generator a visual inspection is easily done prior to each start versus turning a switch in the cabin for the generator mounted in the engine room. The portable generator does not need to be ignition protected. A marine generator (gas) needs to be ignition protected and a boat owner may have no idea when that safety feature fails. A portable generator can be moved to orientate the exhaust fumes away from the boat vs the fixed location of a marine generator. A portable generator is typically started by pulling a rope and no need for a seperate battery and DC circuit which could possibly cause a fire. Maintainance of a portable generator is much easier and less expensive; no need to put it off till the end of the season.

Although I have not read many stories about people dying form CO from generators, the ones who did die had a marine generator. Using a marine generator with all it's special regulations leads to a false sense of security.

All the same things that happen with built-in generators. And happen more
often with built-ins. There is simply ZERO evidence that portables present
any greater danger to boaters. Zero. You'd think it would be easy to find
USCG reports of the deaths if they were happening, no? It's easy to find lots
of death reports dealing with built-ins.

Winter has just started!

When I think of using a portable generator, it's something that is used occasionally and does not justify the cost of a marine generator. Someone who needs electrical power many/most day/night they use the boat should consider a marine generator. In my case, I doubt I run the portable more than 20 hours a season. Usally a hour in the morning to make coffee, battery charger, and hot water. I never carry additional gas for it. The biggest downside is having it take up space in the cockpit.
