    This the first time I have bought a generator, so having read all the reviews , I decided to go with this one , I am solely using it for camping and fishing , so it needed to be quiet , I can tell you that it is , also it’s very light , it works perfectly in charging up my bait boat , iPad pro , and also I have breathing machine to aid my sleep , and of course phone, so in all I would recommend it , plus it arrived at lot quicker then the advert said , I’m a very happy fisherman

  8. Maureen

    Machine looks practical, have filled and started it up – unfortunately a bit louder than I was expecting but until we have tried out with our caravans will not know how loud it actually sounds outside in a field!

  9. Callum

    This item was delivered within 2 days and after a quick read of the instructions I was able to start using my Generator, It runs perfectly and hardly makes a sound.

    Overall I’m very impressed with this product and find that it does the job I bought it for very well, a very happy customer who would not hesitate to use this company again.

  10. D Stinton

    A delayed review as I purchased and did not use for a month and half. Prompt delivery turned up well within delivery window. Packaging in mint condition. Add oil and fuel and it’s ready to go. Started on the first pull to my surprise. Under load load it was quieter than I expected. Infact you don’t notice it after a few minutes. Also light and easy to move around. I have used this for a set motorcycle tyre warmers which proved no problem. Great bit of kit

  11. Gash Bhullar

    Never used a generator before so wanted to get something that looked reliable. Brought it on Amazon and received quite quick. Followed instructions. On eco-mode it does seem reasonably quiet but of course i have nothing to compare with. I put the oil in (used Mobil Super 1000 15W-40) following instructions and added the unleaded petrol.
    When putting the generator on load it responded well (I attached a James Martin Table Top Grill with Flat Plate) which was at the limit of its load capacity and it responded well, obviously a lot louder as it worked but that’s expected.
    Overall the Generator looks great and will be testing in earnest soon!

  12. Kevin

    I have a narrowboat and great little generator it is actually quieter running than my Honda suitcase which was stolen , it starts first time and it is quiet clear from the build that some German Enginering was involved. Recommend.

  13. P Chapman

    OK it is a lot quieter than other generators. However on a camp site with children asleep you will still annoy the next tent. So charge in the day a leisure battery.

    Then run silent battery at night. This generator is great when the sun is obscured and the solar panel has little output to refill the discharged battery. I am talking about a crowded camp site where tents are on top of one another like sardines in a tin.

  14. Faisal

    Very Quiet and easy to start.

    I waited weeks for this model to come back into stock. It’s specifications and value for money beat the other brands in the market. As with other reviews, I simply added the oil and fuel and it started first pull ! I intend to use it with our motor home for the times hook ups are not available. I’ve also used it around our farm to power saws and tools where running mains extensions were not possible.

  15. Pete B

    This arrived 2 days earlier than expected. The parcel was clean and totally undamaged (unusual for heavy equipment) and the generator was well packed. Instruction manual was clear and concise. Just needed filling with oil and fuelling and it fired up first time.

    Given it 3 more restarts since with no problem prior to getting ready to take camping. The build quality is very good and it runs quietly for a generator. It can be picked up with one hand but remember, it is an engine so I’d recommend a small trolley if carrying it any distance. Look after it and it will look after you.

  16. Richard

    Great generator. Runs for just over six hours on a very full tank.

    Had a little trouble initially as it would start but not rev up to clear the overload light. Tried turning it of several times to no avail. Switched off the fuel and let it stall and that cleared the problem.

    No problems since the initial glitch.

    Looks great too.

  17. Maggie Truran

    Excellent customer service. Bought this generator for motorhome so we could go anywhere off grid in this country and abroad. Tried and tested. Looking forward to long holidays away.

  18. Maggie Truran

    Bought this to go off in our motor-home in this country and abroad, off grid. Sent to us really quickly and well packaged. Tried and tested at the weekend. Good piece of kit.

  19. Peter Wheatley

    A very good product. It operates quietly, which is important. It didn’t use much petrol when running for over 8 hours to run a stall at a summer fete. I can’t yet comment on reliability as I have only run it for about 20 hours so far – a long term review of such products would surely be useful for potential purchasers.

  20. Terry Williams

    Excellent generator set up was easy, starts and run very well. Runs a variety of and tools and house hold goods. could not be happier.


    Excellent service. No problem in it starting

  22. William Brook

    This generator was delivered very quickly and looks a nice little unit. I filled it with oil and fuel and it started and ran perfectly. I tested it with the wife 2000 watt hairdryer and it ran as normal. It even looks well in the camp effect.

  23. john ellis

    Bought this product after a lot of generator research over many weeks for my motorhome. Don’t regret my choice at all. Generator is very quiet and powerful, runs my microwave, kettle and all my other equipment, but not at the same time. Very easy to start. I thoroughly recommend this product and Union Mart.

  24. Cloud R

    Looks good, well made and does what it claims for a keen price.

  25. Chris S

    Great generator and feels very robust. Even has a fuel gauge which I have never seen on previous generators

  26. Jamie Jones

    Bought this product with very limited knowledge on how to operate but it turned up on my doorstep very quickly after purchasing and the instructions were very clear and detailed.

    Easy to operate, lightweight and does a good job without too much noise.

  27. Alina

    Great seller and excellent product. Generator very similar to honda ones but much cheaper and value for money. Definitely recommend. Very fast delivery

  28. Stoogie

    Like that it’s not too loud and though not exactly light it is portable and powerful enough to power my motorhome.

  29. Steve Gill

    I bought this generator as a back up for when caravanning off grid. For it’s size it packs a punch and is convenient in terms of size and weight. After filling with oil and fuel it started first time and does what it claims. It is quiet enough not to be annoying and powered a 2Kw fan heater as a load test with no issues. As a back up for our small caravan and also to keep the batteries charged it is just what i was looking for. It also looks the part with it’s snazzy camo acoustic covers. I could have bought a cheaper open framed machine but they tend to be noisier, heavier, and larger and it’s easy to come into contact with hot parts. Ultra quick hassle free delivery was also included in the purchase price.
