Perfect for emergency use, and great value
This is a small, compact, 2-stroke generator which works very nicely. Its also about the cheapest generator available. I bought it for emergency use in power cuts - my only water supply is from an electric borehole pump which consumes about 630W. It only takes a few minutes to fill my water tanks, so I would never need to have a generator running for hours. This generator idles nicely when the power draw is low, and switches to full power when the load increases.I would not recommend it for daily use, or any kind of "off-grid living" application. Like all single-cylinder 2-stroke engines, it has a lumpy, rattley idle and is shrill on full power. It makes a similar noise to a vespa scooter. But they are generally reliable, simple and easy to repair. Because the oil is mixed with the petrol, the exhaust is smelly.Finally, the AC it produces is probably not perfect - the voltage is about 225V and the frequency varies between 50 and 60 Hz depending how fast its running. So the electronics is probably not the most refined. But all the devices I've plugged into it have worked fine, so it seems to be good enough.

Great generator
It’s an amazing little machine. I have it running my caravan. It charges everything I need, quiet and runs on virtually no fuel. I have had it running for 4 half hours and it still had fuel left. I would definitely recommend this generator to anyone who wants a small portable power supply that is very cheap to run

Under powered and two stroke....
Only 650w which is pretty well useless for anything other than charging basic non digital stuff.Top tip, you can buy a four stroke 230v that has 2800w output for only £35 more than this thing direct from manufacturer.....
