On just buying a 800 watt 'two' stroke petrol generator from Aldi, we have
heard from someone who says that he has got one; and that his is running very roughly, and is really noisy. Also it says in the instructions that it is *not* suitable for connecting to televisions or other sensitive electronic equipment. Has anybody any experience with one of these very cheap generators ? (Only £59 ). Also saying they are not suitable for sensitive electronic equipment; would that just be the manufacturers covering themselves? Would buying something like a *surge- protector* make it possible to use the generator with a portable television? |

Equipment that's senstitive to those may indeed break. Sylvia. |

No way I'd connect one to anything of mine. Gareth. |

Likely it is not just acoustically noisy but electronically noisy too and the ignition system radio emissions will cause snow on a portable TV. It might be so rough and ready electrically either voltage or frequency wise that it could fail or wreck some old sets completely. I'd expect most modern switched mode PSUs to cope with almost anything but then you are taking a risk since the maker says it is unsuitable.

Charging up a battery to use with your TV would get around this and be quieter. -- Regards, Martin Brown |

Agreed, but the waveform has got to be very odd before nasties like core saturation start taking place. OTOH, transient crap tends to just be slugged by the considerable L of the primary winding. The fundamental waveform of this generator is still likely to be a pretty fair sine wave, irrespective of its voltage and frequency stability, and how much spiky garbage is floating on the top. Of far greater concern with iron cored trannies, is their response to being hung on the end of a non sinusoidal inverter Having said that, ive used a genny to power a laptop for watching TV on in a camper.

But it may well be fine if the device has a switch mode power supply that's happy with an input voltage of 80-26V and couldn't care less about the frequency because it rectifys the mains. |

If I was using one I'd wire in permanently a baseload 100W mains bulb (assuming you are allowed to start up with a pre-existing load) . If the lamp flickers /wavers then no use with a TV but if a constant light output I'd try only a sacrificial old TV with an old set-top box , if the picture rolls from lack of frequency control then at least I tried. |

If the device can't handle a little frequency and voltage variation with a little noise on it, then the device was designed as a cheap, get it out the door garbage money maker. P.S. I have the 2000 Watt Peak generator that Aldi's has or did have. Yes , it is a little noisy however, frequency only varies +/- 3 Hz from what I could see and voltage was with in reason under load changes.. The wave form on it looked almost as good as my 5000 watt Honda generator.. So putting that into prospective, I guess if you think the Aldi generate is crap, maybe I shouldn't use my Honda either! jamie |

No, you need a bigger one to electrocute yourself, Maynard. Those small generators put out a crap waveform, and are intended for resistive loads. That Honda has a cleaner output but nothing like the AC mains used to, before SMPS became common. |

I have a similar generator, and I think there is labeling caution in using electronics. The little generator is very quiet with no load. With load it's a lot louder. I do have a big Aldi generator of 5kw continuous. It's pretty quiet, but does not get much louder with load. I understand there about 4 companies in china making generators, for Honda, yamaha, etc. The bigger generators all have the same look, but the smaller ones are different. My $350 dollar generator looks like a $2000 yamaha. After I paid $350 , they went to $300, which is at least $200 cheaper than anything of comparable type, including harbor freight. Greg |

All 2 stroke engines are noisy. 4 stroke engines are much quieter. Running "rough" could mean no regulation. This generator is a piece of junk. Also it says in the instructions that it is *not* suitable for connecting to televisions or other sensitive electronic equipment. That's because the voltage and frequency output is probably not regulated. Light bulbs, heaters, and resistive loads might survive. Anything electronic or that uses a motor, probably won't. Has anybody any experience with one of these very cheap generators ? (Only £59 ). No experience. I don't need to stick my hand in the fire to know that it's hot. Also saying they are not suitable for sensitive electronic equipment; would that just be the manufacturers covering themselves? Yep. Unsuitable for any purpose other than making lots of noise. Would buying something like a *surge- protector* make it possible to use the generator with a portable television? No. If the generator goes into over voltage, even for a few fractions of second, the MOV (metal oxide varistors) in the "surge protector" will explode, catch fire, and eventually blow a fuse. Surge protectors also don't do anything for changes in frequency. Look into various "inverter generator" offerings. They're quiet, efficient, low RFI, and have a fairly clean and regulated output. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

Green wrote On just buying a 800 watt 'two' stroke petrol generator from Aldi, we have heard from someone who says that he has got one; and that his is running very roughly, and is really noisy. All 2 stroke engines are noisy. 4 stroke engines are much quieter. Running "rough" could mean no regulation. This generator is a piece of junk. Not necessarily, it may be quite adequate. Also it says in the instructions that it is *not* suitable for connecting to televisions or other sensitive electronic equipment. That's because the voltage and frequency output is probably not regulated. Yes. Light bulbs, heaters, and resistive loads might survive. The last two certainly will. Anything electronic or that uses a motor, probably won't. That's just plain wrong if it has modern switch mode power supply. Plenty of those are very happy to operate over a range of 80-260V and couldn't care less about the frequency because they rectify the mains. Has anybody any experience with one of these very cheap generators ? (Only £59 ). No experience. That's obvious. I don't need to stick my hand in the fire to know that it's hot. But you don't understand about modern switch mode power supplys. Also saying they are not suitable for sensitive electronic equipment; would that just be the manufacturers covering themselves? Yep. Unsuitable for any purpose other than making lots of noise. Wrong. Would buying something like a *surge- protector* make it possible to use the generator with a portable television? No. If the generator goes into over voltage, even for a few fractions of second, the MOV (metal oxide varistors) in the "surge protector" will explode, catch fire, and eventually blow a fuse. Surge protectors also don't do anything for changes in frequency. If the TV has a switch mode power supply, it wont care about the frequency. Look into various "inverter generator" offerings. They're quiet, efficient, low RFI, and have a fairly clean and regulated output. |

Maybe. A power line surge proved to be too much for the surge protector my old Toshiba CRT TV was plugged into. Could it be a private labelling of this Einhell generator? I found a polyglot owners manual for it. http://www.produktinfo.conrad.com/da...n_fr_cs_sk.pdf |
