You know, all this modern stuff is ok but a little 1k Honda generator is still hard to beat . Very quiet , once it's been running a while you would hardly notice it . I know Jean likes to stay in Park4nite places and it would be perfectly acceptable in most of those.

Turn a diesel engine over for maybe half a minute then.

Brexiters. It's your sh1t now. Whatever happens nationally and internationally you own it. I wish you luck. I think you're going to need all you can get and then some. Friday 13th December 2019.

We can also get into the mechanics of transfer of amps here. Using a pair of jump leads will enable one to start a car with a fairly dead battery. I say usually as often getting a good solid connection from all four crock clips is more luck than judgement. Often just one lead not making a really good connection will limit the transfer of amps just when you need them. In this event one can often feel each clip to detect the offending one which will like as not be hotter than the others. Then making sure that warm one has a better connection might just be the difference between starting and just grinding over.

Also as and when all four clips are making a good contact, running the donor vehicles engine will transfer some amps into the 'dead' car battery and after 15 or 20 minutes can replenish the 'dead' battery with sufficient amps to enable starting again.

Ha ha , yes they used to be about £1000 , now around £800 but now and then they come up 2nd hand . Do not be tempted by the cheaper makes . Last time we used ours we were in Gavarnie and parked beside a French man . I went across to him and did my best to explain that we needed to run the genie for a bit and would he be ok with the little noise it made. He seemed to understand and he nodded his head in approval, however about ten minutes later he arrived at the door carrying his full toolbox to fix the gennie for me - so much for my French.

...and fairplay to a good Samaritan French neighbour.

I still have and use our 21 year old Kawasaki GA 550A, the first "Accessory" bought when we picked up our first motorhome, a Hymer 544 in February 1993. It travelled with us for 16 years before we had to call it a day and, I must add, never let us down. Although only 560W it would run everything in the vehicle including an Avtex TV with a satellite dish, when added, all evening.

Give me a small generator every time 100% better than any Solar Panel.

I don't think I'd ever consider a generator instead of a solar panel. No matter how little noise they make they're still a lot noisier than a solar panel! And some people are more aware of noise than others.

But thanks for the input.

Their owners regularly seem to be the only ones deaf to them.

Oh yes, the whoooosh doors! I'm convinced that those who own them need the toilet much more often than others and also smoke an awful lot more than others!

We have a Honda 1.0 generator, bought off the Classified section on here for around £500 about 13 years ago.

We have used it ONCE in anger, parked in total isolation beside a river with a leisure battery that was on its last legs.... two new ones fitted the following week AND two solar panels.....

It has NEVER been used since except once in the garden.......

We no longer even carry it with us so probably ought to get rid of it, but......

I doubt that we will "just in case".
