Hey Guys

I'm new to all this I know that there have been heaps of Posts on GMC generators but I'm not to technical with em.
I was looking at getting one from bunning just for camping to run 2 lights cdplayer and maybe a fan. Also maybe capeable running a small portable fridge. I know there are 2 models theres the 850 watt Peak for $168 or the 750 watt peak for $98.
Would the $98 be perfect for that?
Would the 750watt be capable running a small tv with nothin else connected?

Thanks

hi rodO
I bought one of the 750 w $ 99 ones a cpl of weeks ago
I was @ the MS gathering on the weekend
i ran a waeco 80 car fridge
charged up
2 laptops & a battery charger without a problem
works great fairly quiet & small enough not to have to worry about if it's going to fit in the car or campertrailer
I'm more than happy with mine in fuell useage,noise & load capasity
But again depends what you end up using it for warren

Cool thanks so you reckon there is no need to spend the extra money for what I wanna use it for. I dont go campin all that often anyway. So it would have no problems running couple of lights n a cdplayer and a fan all at once. Proply use to to also charge my mobile witch I dont see any problems doing.
Also it would be interesting to hear what you guys have had running off it. To give me a idea on what sorta things its capable of powering.

Thanks For any advice

Oh yeah I forgot to say I think that the 750watt is discountinued cause it isnt on the website. So must be some old stock bunnings have so should I have any reason not to get one if its discontinued for warranty reasons? And just pay the extra n get the 850watt so if it did die they would more likely beable to replace it.

Rob0,

With what you have to run why not try a 900 battery pack from Supercheap. I run two fluro lights each night which when camping lasts at least a week before the need to re-charge the battery. It comes with 12 volt cigerette charger as well as the 240 voly which allows me to boost it while doing day trips around the camping area.

The real turn-off for me with generators is the noise which really intrudes on the real enjoyment of nature and the sound of silence that can be enjoyed. It would be like putting a thin blanket over the stars at night that still lets some light in but not the true display on offer.

IMO generators have there place, but give me a battery pack anyday for $59, no fuel no noise and total silence.

Cheers,

Patrick

Patrick , a$59 battery pack is like t-ts on a bull if you ever want to run a compressor type fridge, you say no fuel no noise and total silence , ,funny that when camped two dunes back from the beach with the gennie running can still only hear the surf., even the park rangers have commented that the new generation of "cheap" generators are so quiet and inobtrusive that that their use is preferable to an idleing vehicle trying to recharge batterys....Noisy B-lls-it

The 750 is still available as we put 2 pallet loads on display today Bunnings Geraldton wa, we also have 850 950 and 2300. Best way to tell if you can run all u want is to check how many watts each piece of equipment is (usually printed on equip or in book) if they add to less than 750 then thats for u.
I have 750, and a mate has one. They are 2 year guarantee so keep receipt

what moss is saying is correct except things like your fan or fridge require up to 3 or more times the draw to startup. Anything with an electric motor or coil will be similar but once running will be ok.

Hi,

750 is plenty for what you have in mind. If it has a 12V charging output as well, beware that is meant for CHARGING only. Don't even think of connecting any 12V gadget to that output without having a battery connected at the same time. Without a battery as a buffer, the voltage at that outlet can get as high as 18V.

Cheers

750watts is heaps!!! Your flouros are lucky if they are over 20watts MAX!! I have a Honda (old) 500 watt EM500 and it will happily chug away running 58cm TV, VCR and fan (load shedding summer Brissy 98).

While camping I have run 4 tents lighting and charged plenty of batteries etc with it, so I dont see where 750 watts would ever give you trouble. In Karbarri the Raid X challenge up there was using a 750w GMC to run their stats board constantly for three days and nights. Computer, 240 volt spotlights and a large 1m LCD monitor!!

Just remember to keep a reasonable load on it if it is running. The glazing up that can occur if not loaded sufficiently shortens the engine life sugnificantly. ie dont just have one 14w flouro on it for hours.

Enjoy

Matt.

To calculate watts - requirments see http://www.poweriseverything.com/impt-info/load-form.html

if your total requirements exceed the capacity of your gennie then buy another!!

The 750 w should be heaps, I've got one and it will run a 750watt drill with no probs just get it up to speed before attempting to make the drill work. I've run two 100mm angle grinders off it at the same time too.
They do get a bit quieter after a few tankfuls of fuel as the muffler gunks up a bit.
Second the comments about the 12v output too, 18.5v without much of a load.
If it dies just take it back and they will probably replace it with a 850 as the 750w are not around sometimes. full 2 years replacement wty too.

Those GMC generators are a clone of a Yamaha. I have had a yamaha genie for a number of years (650watt) and run two fluros 13watt, an Engle fridge an Elextrolux fridge and a 35cm colour TV off it although it does groan a bit on starting up the TV but doesn't come out on overload.
If you buy a genie that is bigger than your requirement you will glaze up the bore in short time. So don't buy a genie larger than your needs. I would suggest that the 750 watt would be adequate for most needs.
I also connect mine to a 150' extention lead so that I can put it well away from our caravan and reduce the noise level and I have not notice too much voltage drop.
You will have to adapt a cable that has a 10amp plug on one end and a 15amp socket for yor caravan. These things work better when they are worked hard
