Rated 5 out of 5 by from Handy little generator I bought this after reading some of the reviews on here. It's initial purpose was for our caravan so we can be 'off grid' when needed. It is simple to operate, has concise and easy to understand instructions. And it's biggest selling point I'd say is just how quietly it runs even when under load.

Rated 5 out of 5 by from Great little generator I bought this off the back of a guy using a 1200w circular saw to build his own motorhome last year. 1200w saw with long extension cable. I bought one off his recommendation of best for the money out there. Set mine up for my caravan and after run in. I ran it straight for 8 hours straight on a full tank of fuel, albeit to keep my battery topped up as I watched a normal TV as opposed to 12v

Rated 3 out of 5 by from generator brought to run caravan electrics .not really up to the task

Rated 4 out of 5 by from Good lightweight generator Bought this for powering my amateur radio equipment, excellent performance with a variable load except that the inverter does produce a high level of electrical noise below 5MHz. Nothing detected above that frequency into the UHF spectrum. However a good in-line filter at the generator output should reduce this to acceptable levels. Would be 5 stars throughout if the manufacturer had added a bit more internal filtering.

Rated 2 out of 5 by from Impax IM800 Thank goodness for fantastic screwfix customer service. This little genny is great whilst working , however my first one was faulty almost immediately from the box. This one started first time but after about 1 hour of faultless running it refused to idle at a steady rpm. Instead it sounded like someone was revving the engine up and down constantly, even with no load! Screwfix were brilliant with the exchange and the second one ran perfectly for 7 months. (about an hour a week charging a leisure battery). This one then decided to keep cutting out, with the overload light coming on. This would happen even with no load attached. Interestingly it would run fine in Eco mode but if this switch was turned to normal mode it would sometimes run for 5 minutes then cut out (no load) and sometimes run for only a few seconds. Screw fix have been brilliant and offered an exchange to a different model. Shame really because when this little, lightweight genny is running it is reasonably quiet and very economical. PS I was meticulous about the routine oil changes.

Rated 5 out of 5 by from Awesome generator Bought this for my caravan and it was perfect for the job using way less fuel than I anticipated. It is lightweight even when full of fuel. It is quiet when running and easy to start.

Rated 5 out of 5 by from Great generator Brillant powerful unit only would recommend. Runs all day on one tank full with low usage.
