Impax IM800I 700W Inverter Generator 230V is rated 3.9 out of 5 by 7.
Rated 1 out of 5 by from Reliability I have had this generator for a couple of years. It has run for less than fifty hours, but has developed a fault. It runs for twenty minutes then dies. It will restart immediately, then run for five minutes then cut out. I would love and advice on how to cure the problem, because it is of little use to me as it is.

Rated 4 out of 5 by from Nice design, good quality product, some quirks I now own two of these excellent and good-looking generators. They're very easy to transport by car and to carry about by hand. The output from them is so steady that an attached lightbulb hardly flickers. They are easy to start and, on low loads, run for several hours on a tank. Would have rated them 5 stars but for two things - 1) they are quite noisy, especially on high loads, and 2) to check the oil you need to remove one of the covers, held on by 4 screws. The noise is likely a trade-off in producing something so compact, but the oil filler seems to be a design flaw - in any case I've never come across such a system before. At the very least they could have used butterfly nuts instead of screws. Overall, however, very pleased with them and would recommend.

Rated 4 out of 5 by from Good value Decent output for use on our allotment with all tools bar the lawn mower. Also use it with our motorhome, charges the habitation battery and powers small mains devices when there's no hook up. Great value.

Rated 4 out of 5 by from Gene for caravanning I bought this gene to charge my caravan battery on a seasonal pitch, which it does well. It is slightly noisier than its Honda equivalent but at half the price who cares. The only disappointment was that it cannot connect via the caravan's power input socket as this requires a higher amperage and when connected the gene 'cuts out' as it is not capable of supplying the required power. To overcome this I simply connect directly to the battery but clearly none of the internal 3 pin sockets become live. It is also light and small enough to put in the doorway of the caravan for security without blocking access. A great buy but if you want to run your caravan like it was on mains power you will need to buy at least a 2,000 watt gene!

Rated 5 out of 5 by from Superb My generator broke down so I was desperate for another for use with my caravan. This Impax 700 is perfect for my needs and does what it says on the box! It is light and efficient. Started first time and is quiet and economical compared to others I have experienced. NO flickering lights unlike none inverter generators I have tried and perfectly safe for my laptop and digital TV. Thanks also for the excellent sales staff at the Wrexham branch. They couldn't have been more helpful. Well done Screwfix!

Rated 4 out of 5 by from powered up a compact efficient generator, not a huge power output but more than sufficient for most everyday needs such as battery charging or running small pumps etc.

Rated 5 out of 5 by from Many hands make light work. Bought to power gas boiler & pump when ye winter wynds do blow. Generator is a four stroke inverter type with 'pure sine wave output' so will power Wifi routers, computers and boilers ok. I tested it on my central heating, all good. This machine produces enough juice to easily power a 550 watt hedge trimmer,(tested) and that is enough for lights and the boiler. Requires 10w40 oil - not supplied) and then fires up on the fourth pull. The Eco setting reduces the throttle on low demand, and seemed to work well. Genny seems nicely made, UK 3 pin socket on the front and a set of 12VDC charger leads for batteries. Even the supplied screwdriver is nice. About three hours running on a fill, I'm told so it could be anything. Light enough to be lugged around, a perfect backup for the coming winter. Quiet, but not that quiet. Love your neighbour.
