Impax IM800I 700W Inverter Generator 230V is rated 4.3 out of 5 by 42.
Rated 5 out of 5 by from Quite. Cheep to run. 10/10 Brought for our caravan as we often have non elc pitches. Batt charger works well on 110a batt from flat. Also powering batt charger from 240 socket in van with 2 x 110 amp batt. After putting £2.50 worth of unleaded at £1.19 she ran for 11 hours. Very quite and starts very easy. 10/10 Only wish she had a higher amp charger but then she would drink more fuel. Don't forget your oil as she has none when brought. You can get the oil from screwfix at the same time. Rating on reliability as 5 stars as I have not had problems yet. Also I have had a kopor gen and this was very loud for a silent gen so much that I sold.

Rated 1 out of 5 by from Absolutely no supression I bought this generator for use in my Amateur Radio hobby. Last night was the first time I tried it. It is absolutely unusable for the reason I bought it, there is absolutely no RFI suppression built in. Should someone complain to OFCOM if you use this generator in their locality you could be ordered to cease its use under current law.

Rated 5 out of 5 by from Fantastic value For the money, this small, lightweight generator is amazing. Used it yesterday for the first time (after setting up) for 2.5 hours charging my lithium batteries. Started first time and ran faultlessly. Quiet, small and efficient. Shame the oil isn't included as not everywhere sells 10w30. Would also have liked a USB charging point, but for the money this generator can't be beaten!

Rated 2 out of 5 by from Noisy and unreliable I bought this generator just over 12 months ago and have used it a handful of times. First things first, it's not quiet by any means! 93db! Secondly a week after the 12month warranty expired it kept cutting out while connected to our caravan. No offer of an exchange or refund. Next time I'll invest in a Honda generator!

Rated 5 out of 5 by from Great Value Generator I bought this generator at short notice for a trip where I would need off-grid power. This 4 stroke generator proved ideal with first pull starting, quiet running and good runtime between refuelling. A great value, compact and easy to use generator.

Rated 5 out of 5 by from Great for Farmers Markets I've used this generator for three months and it's been wonderful. It powers my Potters wheel which I take to Farmers markets. The new one is an exchange as the last one developed a fault. The new one runs a lot better from the box. Screwfix were wonderful with the situation and changed the item without delay. Customer services were good and helped by sending a copy receipt by email to facilitate the exchange and advising which local branch had the item available. At the Taunton (Crown) Branch the exchange was made in minutes without fuss. The only questions were "What went wrong?" and had the oil and fuel been drained prior to return?. In and out in about 5 minutes and highly delighted. Screwfix customer services highly recomended!

Rated 2 out of 5 by from LOUD!! I am an electrician but purchased this for a caravan holiday. The main reason for choosing this product was that it is advertised as quiet. It charges and runs fine. The fiddly bit of finding and filling the oil a bit frustration having to unscrew the orange side panel. It chugged quite happily charging a caravan. I tried it at a little less than 700w with a power tool and quickly shut it off as it didn't particularly like it. Revving hard to keep up the power. My main issue with the unit, and my reason for returning it to store, was the noise. It was advertised as quiet. The packaging says 56db. Once you run it it is very obviously not quiet. In fact labels on the machine and instructions give the sound as over 90db. When I started this on a camp site it caused people 100m or so away to turn and look. OK for a site but definitely not a quiet suitcase genny, Very disappointed. Looks the part but fails to achieve what it is advertised as.
