Im looking for one, do you know of some other good deals about then? Cheers

I am looking for a 'better one'! However, not sure what a 'better one' could look like. Any advice?

Better ones might be red with Honda written on them, but might be a bit more expensive than this :whistling:

Yes just what I thought would be quoted. Get a grip. This is a good deal for those of us who are not generator snobs and a bit shy of a bob or two. If this does the job at time of purchase then it is a result.

PS. I was taking the p..s. with my original reply. Seems to have been lost on you.

That's abit obvious really, you could apply the same logic to anything your prepared to pay twice the cost!!

A tank full :-D

If you want a genie to boil a normal 3KW kettle, then you need to spend at least 6 times the amount! Although this will boil smaller travel kettles.

I have seen similar spec genies for the same money, but not with 3 year warranty, voted HOT!

I'm after a car for 3k, could you recommend me one for 5k? :whistling:

Looks like a great deal for the price and the 3 year warranty will at least give some sort of peace of mind.

Hot from me.

heat from me

looks same as this one @ £78 http://www.screwfix.com/prods/89480/Power-Tools/Generators/Sumo-SML34GEN-650W-Generator

or heres a more expensive Honda http://www.screwfix.com/prods/94610/Power-Tools/Generators/SDMO-SH6000E-2-6000W-Generator of course the snobs won't like that one as despite having a Honda engine, it doesn't have 'honda' splattered on the side ;-)

wouldnt genie grant you 3 wishes ??

you could boil 3 ketles and have 1 cup of tea

or you could buy a cup of tea for 50p and keep your £100

you just spent on a honda

only joking

I beg to differ

you ; :oops:

me ; :-D

ive used it fine to power lighting in a tent and also run angle grinder and drill no problem

great tool

PS. I was taking the p..s. with my original reply. Seems to have been lost on you.

That was a good rant at someone who was also taking the ps.....the original poster hasnt yet replied!!

It will boil a travel kettle. If you have a large garden without a long extension lead, it would power a smallish power tool. I have a big garden & rely on petrol powered or rechargeable tools. Since buying this generator 3 years ago, it has been used twice for little jobs. Before you buy it, ask, 'Do I really, really need it'. It is also 2 stroke , so you have to mix the petrol & oil together.

Long running normally means 18 hours or so! So much larger tank needed for "long running"....

Although running times and petrol consumption depends on the load on the generator.... six hours may be far from "six hours" when appliances are pulling peak power :?

Also note that if you are going to use petrol from the petrol station and leave it in the tank for a while it will "go off" as petrol has a shelf life of weeks. So put some extended life petrol preservative (available at garden centres with petrol mower sales etc) to preserve the life :thumbsup:

And I agree that Honda motors (irrespective of brand of generator) are quality :)

So this is hot for value, but won't last six hours when connected to electrical appliances :?

Be really careful when refuelling a hot generator - risk of explosion :thinking:

i have found best place to look is ebay loads of 2.5 to 3kva 4 stroke ones. engines are exact copys of honda go for about £150 or less new.I got cheap 2.8 kv £118 used it loads for about 4 years been more reliable then expensive honda one at work.I also have cheap 4kva diesel for power at stables there only about £350 new is electric start as well and cheap to run uses cheap gas oil lots cheaper than petrol (no tax)

no sh*t - sherlock :roll:

One of the most pointless postings I've ever read on here. What if you don't have the extra £50? Looks like a deal to me, heat.

Why? This generator gives out 230V AC, an invertor converts DC to AC.

A kettle actually uses a shitload of electricity. Just because it is a a common household device doesn't make it trivial.

Equally I can state facts to make this sound awesome like

"This could power 77 energy saving light bulbs (11w) or 1700 0.5w LEDs."

which it could, it has 850w, its not that hard to understand. you could run 8.5 100w tvs, just read the manual for your device to find out how much electricity it uses.

The fact is this could, while say camping or in a power cut or something. Power a TV, light, laptop/phone stereo any many other things. If you want to power anything thats designed to make heat however, like a kettle, stove or even a hairdryer then don't bother.

Although it says 850w, this is peak. The constant power is 650w.

I still think it's a good deal though.

I still think it's a good deal though.

oh ye, still its not bad. However by my calcs 850w peak = 600.95w since you would take the rms value which is 0.707 of peak.

But that does make me wonder, will you really get that much output? I am more sceptical now after noticing that.

Nothing to do with RMS. Peak power on a RMS signal is the power at the positive negative peaks of the sine wave, which is less than 1mS. This is talking about peak power for seconds, or even minutes to allow for surges.

Anyway, when calculating peak power, as power=volts*amps, the figures you would use is 0.707*0.707=0.5

If someone buys a laptop or PC, or TV etc? This would do the job of them plugging them in and testing won't it?

Anyway, when calculating peak power, as power=volts*amps, the figures you would use is 0.707*0.707=0.5

What are you talking about, thats how you calculate current in an AC signal.

p=VA so since this is 230v and 850 watts peak meanint

850 watts / 230 volts = 3.69 Amps

in order to calculate the current in an AC signal we take the RMS (root mean square) of the AC signal.

so thats 230 volts / square root of 2

square root of 2 is 1.41 so:

230 / 1.41 = 163.12

So we have the amp and the RMS voltage now so just use V=IR

163.12 * 3.69 = 601.9128

or if you dont need to be so accurate you can just use the cheat of multiplying the watts by .707

ooh whats that?

850 * .707 = 600.95, close enough don't ya think?

And there's no such thing as an "RMS signal"

p=VA so since this is 230v and 850 watts peak meanint

850 watts / 230 volts = 3.69 Amps

850 * .707 = 600.95, close enough don't ya think?

And there's no such thing as an "RMS signal"

Again,

RMS voltage = 0.707*V peak

RMS current = 0.707*V peak

Power = VI

Therefore 0.707*0.707=0.5

So Power(RMS)=Power(Peak)*0.5

And as I said, the peak power they're quoting is nothing to do with RMS, if you think that, that's your loss. Glad you found a typo, but my maths & theory's correct, yours isn't. You'll find http://www.tonmeister.ca/main/textbook/node82.html backs up my theory. Also read post 6 of http://www.autopia.org/forum/car-detailing/109307-generator-enough-power.html

RMS voltage = 0.707*V peak

RMS current = 0.707*V peak

Power = VI

Therefore 0.707*0.707=0.5

gah im saying the "current output" is RMS not the peak, its too late to do more maths, maybe ill do it tomorrow.

from the link,

This number turns out to be 0.5 of the peak power, or, in the above case, 0.5*28900 Watts, or 14450 W as is shown in Figure 2.5.

The point is to calculate peak power you use peak voltage & peak current. To calculate RMS power you use RMS voltage & RMS current. You didn't follow that rule in your calculations.

Your calculation

850 watts / 230 volts = 3.69 Amps

Is this peak amps, or RMS amps? It's neither as you've used Peak power & RMS voltage in the calculation, giving an invalid result.

for another £200 you could buy an amazing one..hell while your at it spend a few grand and you'll be sorted for life. lol (btw i think your on the wrong site.. this isn't whynotspendmorengetabetterdeal.com its hotdeals.com) lol
