Technically Brilliant

The advanced overload detection system will automatically shut down the power output whilst keeping the engine running in the event of a power overload. The low oil protection system will automatically protect your engine by cutting out the engine if your oil level is too low. This intelligent generator allows you to run multiple appliances simultaneously, with confidence. Also, the high quality copper wound motor is designed to last unlike the cheap aluminium wound motors that most generators rely on.

Rapid Power

It’s so easy to get started with your Böhmer-AG generator. Just add oil and fuel, turn the switch on and then pull the Gen-III quick start recoil mechanism. These are designed to be easy to start with minimal fuss.

  1. David Rothwell Hughws

    What can I say….what a machine was super quick only 32 hours from ordering,been using it to run a sds drill and grinder at the same time the generator didn’t miss a beat.

  2. P Young

    Excellent service, very impressed with speed of delivery during these times.
    Easy to set up and started first time have not used it to any extent as yet but feels very robust and I’m sure will be up to what I intend to use it for.

  3. Carl

    Bought this generator, it was delivered 2 days later (which is superfast for the Scottish islands)
    Took about 1/2 hour to put together, added oil and petrol and it virtually started on the first turn of the key.
    Great value for money definitely worth 5 stars.

  4. Charles Christian

    I needed a small generator for domestic use – this model has 2 x standard 13amp plug sockets AND wheels – it is very heavy – as I needed to be able to move it myself rather than find some additional muscle to help carry it. Assembly is straight forward (tho you will need a set of spanners) but the beauty of it is the electric key start. One turn and it starts running – none of that pulling the manual chord start aggro – and let’s face it if you are wheeling it out in an emergency in a power cut (which is why we bought to keep our deep freezers going) you want a hassle-free experience.

  5. David beavis

    Generator arrived next day easy to put together
    Just add fuel and oil turn the key away it went
    Good piece of equipment..

  6. jason

    I had taken the time to read all comments on this and the only ones repeated was the bad user manual but with little or no knowledge of DIY you should with ease be able to assemble this with no problems and to be honest you wouldn’t be buying this with out some knowledge of DIY in the first place. The manual has very useful information in it and the machine is packed well and after filling fuel and oil started first time. runs like a dream. My only issue I had and was a very small issue was that the two nut and bolt supplied to fit the wires on the battery terminals was to large. I just used some I already had slightly slimmer to fit and bolt. All in all a fantastic generator and would fully recomend.

    Union Mart have been excellent in helping with a couple of minor teething problems. Now all sorted. The WX3800E is running OK, even though the user instructions were a bit ambiguous.
    It did state to use the brackets for the rubber feet only on the 5000e and 7000e models, but have found them beneficial on the 3800e as well.
    Packing and delivery times were excellent. Date and timed to the exact minute.
    Love the Bohmer electric starter, saves all that tugging.
    The choke lever is a bit fiddly to access, needing a bit longer lever for not so nimble fingers.

  8. Alan shemmings

    Excellent product. Very quiet

  9. Alan shemmings

    Excellent product.

  10. Scott Rogers

    Arrived exactly as promised, well packaged and easy to assemble. Have yet to start it up but not expecting any problems after reading previous reviews.

  11. Haydn Allen

    All delivered on time as scheduled and once the wheels, Handles,Battery, oil and fuel were filled up the generator started first time.

  12. Andy

    This is the first generator I’ve bought so when it arrived I wasn’t sure what to expect

    It was very easy to assemble I put oil and fuel in as per instructions turned the key and it started just like that it’s quitter than I expected and powers my equipment it’s light and manoeuvrable

    Overall I am very pleased with this product and recommend it



    A really great generator. Amazing electric start.Runs all my power tools with ease.

  14. Michael lees

    Arrived fast easy assembly and started first turn of the key! Happy days

  15. admumrob

    Generator arrived 4 days before estimated delivery date. Very happy with it, already used it to do a few jobs on the allotment. Reciprocating saw and drill ran off it no problem.

  16. Callum

    Real Happy thanks

  17. Coralyn S.

    Really impressed with this generator and my husband loves it! It arrived ahead of schedule very well packaged. He filled it with oil and petrol, connected the battery, applied a little choke, turned the key and it started first time. He has already run a powerful load from the generator and except for a change in engine noise it coped without problem. Just the job he says!

  18. rec68

    Product arrived quickly, exactly as described and works a treat.

  19. T. Knight

    Our old generator recently gave up on us and as we live remotely on Scotland’s west coast, we decided we could not be without this essential piece of equipment.

    The new generator arrived very quickly (within 2-3 days), well protected. We love the electric start, which our old one did not have. The generator has been tested, run in and is now ready for action when required. Very happy with the quality and ease of operation.

    We liked the thought behind including a plug for a two-way lead between generator and the equipment it will provide power for. It has not been used in anger yet but is ready for action. Very happy with the quality of the equipment

  20. Peter P

    Easy start with the electronic ignition. (Key start)
    Excellent generator for a very good price.

  21. Steve500

    ordered this for my garage and was expecting it to be delivered in 5 days,

    it arrived the even before the due date, very easy to put together and a nice quality build,
    turned the key and it started first time, very pleased with it and would use this company again

  22. Fabio

    The product works as expected, I have used it in my allotment in order to supply 1.4kW tiller and it did the job with no problems. Very happy so far!

  23. Delroy Arnett

    fter looking at various petrol generators this one tick all the boxes. Easy to put together no problem, topped up oil and had fuel, follow instruction how to start then turn the start key and it started first first time. It also comes with all the tools you need to assembly the generator and maintain the generator.
    This generator is a great piece of equipment a real bargain and super fast delivery

  25. M. Thorpe

    Wonderful unit, easy assembly ,delivery was very quick, I put in fuel and oil and To my great delight it started at first pull, I wish I had such a generator like this years ago, when electric failure left us using candles,

  26. Ryan

    Fantastic Generator

  27. I Colyer

    As an 84 year old disabled person I needed an easily moveable easy to start generator. The electric start Bohmer exceeds all my expectations. I prepared it for use on my own. The hardest job was filling it with oil!

    The 13amp sockets are great. I was not able to remove the 30amp round socket on my previous generator, it was too hard. Thank you Bohmer-AG for making something with the user in mind.

  28. Larry Thompson

    Really good piece of equipment used it a lot the past 2 weeks. Used it to power my Skyvac with no problems. Started first time after putting oil and fuel in. Key start excellent.
