Small generator for diy power tools

Post by London mike 61 »

Really as per title, I need to buy a small generator to power a drill or angle grinder when I’m somewhere where there is no access to a power source. Does anyone have a recommendation for something that’s portable and can cope with a single unit at a time ( I’m very unlikely to use two units at once ) for short periods.
Thanks in advance

Mike

I bought the Parkside petrol generator from Lidl around 4 years ago. I've had the same petrol in it for 3 yrs :shock: and it still fires up first time. I used it yesterday to hoover my car at my lock up.

'Small' is subjective so I'm not sure what you're after but this one has two sockets. It's A1 for reliability.

Those little inductance ones are double the price you'd be cheaper buying a cordless angle grinder.

Someone told me modern day fuel only lasts about 3 months :roll:

Thanks for that, the park side one looks ok but the most annoying part is that they don’t have a online store and those sort of things only come up probably once a year which is a shame as they are missing a trick there to sell more tools. I’m going to keep looking and I’ll see if I can bag a bargain with a voucher code off one of the online shops.

I am no great shakes with electric stuff but as I understand it you have to be wary of all engine and no output. I see a cheap £125 at Toolstation only generates 750w, about half the power a vacuum draws I think. The Switzer Petrol Generator With Wheels 2.8KW 6.5HP on Amazon comes in at £180 and seems like a good deal. The wheels are handy with heavy bit of kit and the output would cope with most things I guess. I do not really know too much about this but that looks a good solution for you Mike.

Thanks DWD
After a lot of head scratching I’ve narrowed it down to this one https://www.google.com/url?sa=t&rct=j&q ... 5pj55OtoPy it’s German made ( I think ) with copper windings which are more reliable in producing a regular output, it’s got wheels for easier transport and has enough power for me to use a sds 1500w drill which takes a third more power for the start up and even my new chainsaw that’s 2000w will be powered enough.
The bonus is that if we have power cut at home then we can run it to power a microwave or single hob etc to get by until power is restored. Because here isn’t a burning need to buy it tomorrow, I’ll wait for a Ebay voucher code to get a bit off the price.

interesting to know what this means ??
"up to 10 hours run time "
in use or running no load ??
i suspect on a very low perhaps 300w load ??

I recently tried to run my Dewalt 743 from a 2.4kva generator , the saw tried to start , the engine stalled, waste of time as I suspected it would be. The generator was a cheap without makers markings.

Er copper windings , all generators will have copper windings, alternators or dynamos

You could use silver , more efficient tad pricey

Aluminium less efficient need more bigger machine

Any conductive material that will produce a magnetic field when a current is passed through it , with greater but in the main lesser efficiency than copper

Best of all would be a super cooled conductor.

When I start to run it I’ll let you all know!

743 is 2kw running so you would need perhaps 50-100% more for a few seconds to overcome the startup current
https://products.dewalt.co.uk/powertool ... no/DW743N/
indeed on some tools the startup current can be nearer 300%

Yes it is starting current but the fact of the matter was the generator was useless

My table saw is on a dedicated 16amp supply from a C rated MCB for the same reason

I can't help but think a generator may be more trouble than its worth, whats wrong with battery drill and an angle grinder?

Fret not, a forum is a collection of opinions. Above, are mine.


Are you going to be working on anything electrical? have you got a multi meter? why not? Would you hit a nail with a shoe because you don't have a hammer?

If gloom had a voice, it would be me. :mrgreen:

I’ve got a hedge trimmer, chainsaw and other items that the generator will run as well as a stand by for home in case of power cuts.
