Seen this and bought one instore (B&Q craigavon) as I thought it was a bargain.

2500w nominal output, 2800w peak. ie would run most essentials in your house at the same time, eg fridge, freezer, oil heating, lights, computer etc (obviously not your cooker and possibly not your kettle)
110 & 230v @ 50Hz output
4 stroke petrol engine (runs on unleaded- no fuel mixing required)
15l tank, with up to 8 hours cont. runtime
3600 rpm (noisy no doubt)
2 year warranty

The 'rockworth' gen - ie the usual branded one they sell is £259 for the same wattage

I remember they has one similar to this last year for around £69 and people cooled the deal right down, saying that it wasn't going to reliable etc. without any evidence whatsoever. This looks like a great camping accessory for not alot of cash. Even if you only get one season out of it then it'll still be a good deal.

Voted hot!

will easily power a low wattage kettle :) might take a pop down after find out exactly all this can do. voted hot from me..
#4
wow! this is super hot. The £69 one was 650w. This is a proper generator capable or running a kettle or heater or microwave.

Can't see these lasting long. Anyone else actually found one?
#5
So, you can run lights et-al off this, and yes, 2800W is pretty good, but how do you wire it into your mains? A quick read suggests that you need to install a transfer switch which is going to be far more expensive than this unit!

I'd expect this unit to be used to run a few items that plug directly into it via an extension cord, still candle and flashlight time!

If you intend to use a generator for long periods of time for whatever reason then you are best off getting a natural gas one.

Natural gas will cost you about 3p per kWh whereas petrol will cost you about 10p per kWh. Once you take efficiency into account the petrol one will cost some 40pence per kWh and the gas one some 10p per kWh. So if you use it for 1000 hours @2.5kw then the petrol one will cost you £750 more in fuel.

In comparison electricity from the grid costs about 12p per kWh

Mind you, for the worst-case-scenario people out there, you might want a diesel generator. You can't guarantee supplies of any particular fuel so the ability to go and make bio-diesel from cooking oil could make it possible to run in more circumstances :)

well if you can buy a unit with no manufactures name for the price of a gasket set for a named product I would suggest taking out an extended warranty if it is available, as I believe there are no parts available. If you have a problem with the unit and phone the helpline they will tell you to take it back into store for replacement or refund, after the 1st year your only option is to throw it away if it breaks down.

Odd to take for a kettle - why not use a fire?

Anyway, the efficiency seems to be terrible. The 15l tank contains 145 kilowatt hours of energy. But this generator empties it in "up to 8 hours", producing "up to" 20 kilowatt hours of electricity. My guess is that under full load, it only lasts 6 hours, leaving you with 15 kilowatt hours (at a cost of ca 15 GBP!) and a pathetic efficiency of only 10% even under optimal conditions.

That may be fine for very occasional and emergency use, but otherwise do your wallet and the environment a favor and get a proper one. Or, as cells says, one running on natural gas.

Camping accessory? Who in there right mind would want to lug one of these on a camping trip......in any case a camping holiday is meant to be an escape from noise and bustle etc. so these ought to be banned from campsites due to the noise they make.

Fires are not really accptable in the places i want to use it!! 15L in 8 hours is good enough for me i would only be using it at night anyway and its a 4 stroke too so the environment would not take too much of a hit :thumbsup: cannot use natural gas as that is for cooking!!!

Good point, although many of these cheaper units copy Honda generators and most parts are interchangeable. But your point is valid and worth consideration. I think it's one of those things where if you're serious and use it professionally then a more expensive one is in order, but if you just want a cheap high-output unit for light use then this should be generally okay.

If you want peace and quiet then you definitely don't want to go camping on a campsite! Some camp sites I know are the noisiest places you can get! And camping isn't just about tents - it's about caravans/trailer tents etc. You wouldn't be actually carrying it! It'd be kept in the back of the van!

I have a friend who takes one of these + a beer fridge + tv. Home from home!
#14
few of these would power a decent sound system
#15
I'm not dissing this deal, sounds a good price, but what would you use it for? Any examples?(besides after a nuclear holocaust) :thinking:
#16
why not by one of those converter things that plug into your car lighter ideal if you you only want to power your kettle or electric pump or phone charger etc. Just a thought

Because they are 3x the price ... at least the ones big enough to power a kettle. ;-)

There can and have been brown outs killing grid supplies for days (eg new york a few years ago) and severe weather in this country can take down power lines leaving you with no mains for a day or two (happened round here about 3 years ago over xmas!)

Most oil heated (possibly gas ones too - do they need electric to start?) homes with no mains will have no heating, the contents of your freezer will be lost, and you may have no means of cooking/heating food unless you have gas.

So its a £100 hedge against being cold and hungay and living in the dark for a few days.

NOT THAT ANYONE SHOULD EVER DO THIS - but people have been known to turn OFF the mains supply in the event of a failure and just a wire a plug to the end of an extension lead and plug it in to a house socket and then into the generator, thus supplying power to all parts of the house without a costly transfer switch. Do it wrong and your house may burn down, dont turn off the mains and you may kill some poor dude at the top of a pole some miles down the road!!

Oh yeah, maybe you could make money with this. Fill with Lidl veg oil and sell electricity to the grid? :-D

never new the cost so much got mine for free from work

instead of using a kettle
use your microwave to boil the water.
maybe we should all be doing this in any case
to save the environment ( time to import a
container of microwave kettles)

Big stack of them at Loughborough at the weekend when my DH bought one.
Loud but no worse than these things usually are. Great piece of kit, and a very reasonable price, especially if you have the 10% off card they gave out at the weekend.

Maybe I'm being thick here but won't a microwave oven use the same amount of electricity as a kettle to boil the same volume of water..? Are electric kettles much less efficient in comparison? (Ignoring the 'human' factor i.e. boiling more than you need.)

this was also communicated to me when i worked in scotland when a lad from BP grangemouth boiled his water in a micro./...//....

a microwave will take longer to boil the water, but will not draw the same amount
of power as a kettle.
try both ways watching your electric meter during both processes,
you will see significant differences
(ps make sure your water container for the microwave is scratched internally!!)

not hot 2 much but i ordered one 2day

I have to admit I was intrigued by this so did a little experiment just now. Note: This is by no means under laboratory conditions, just kitchen conditions :)

My kettle is 1850-2200 watts so I assumed 2200 watts for worst case scenario. My microwave is 800 watts. A full cup of water (300ml) took 1 min 13 in the kettle and approx 3 min 45 in the microwave. I say approx because it was hot but not boiling after 3.5 mins so I put it back for another 30 seconds and it was boiling when the timer stopped. Both appliances were cold before the test as was the water. A bit of simple maths suggets there's not much difference in energy used between my appliances but maybe lab tests prove different, I don't know. What I do know is the kettle is much more convenient so I'll stick with that, thanks all the same :)

P.S. My water container for the microwave was a cup and was not scratched inside or out... why would I scratch my cup..?

Microwaves can superheat water if the water is in a container that is smooth on the inside, basically the liquid exceeds its boiling point temperature without actually boiling until you move the container or put something into it. You don't want to be holding the container when it suddenly boils as boiling water and steam could go over your hand or face.

See http://en.wikipedia.org/wiki/Superheating for more info.

You could try, but as it runs on unleaded the result will be a destroyed generator engine.

It's not called a suicide plug for no reason you know (Male to Male plug connecting your generator to the mains via a regular socket). You'll also likely blow your 13amp (or lower) fuse unless you go around and turn everything off, switching them on experimentally and slowly.
Oh, and yes, it's illegal.

Any good for camp sites?
