1 don,t buy the 2 stroke cheap generator they cost twice as much to run and are much too noisy to be used on most campsites
we have the honda eu10 which says its 1 kw but really a bit less and it will keep up with the battery for the lights and stuff but if you have a 12volt tv it may not

Cheap or more precisely poorly regulated generators can very easily wreck the caravan's charger electronics so care is needed.
Two stroke engined generators are particularly difficult to speed regulate and this coupled with them likely to be budget units makes them prime candidates to do damage.
Run any generator for a few minutes to get warmed up and improve its chances of regulating its electrical output before you connect it to the caravan.
Under no circumstances let them run out of fuel whilst connected; this puts all including quality machines at high risk of causing damage.
Also avoid switching on and off big electrical loads whilst connected to a generator, the more so a poorly specified generator.
They connect via the EHU.
You don't "need" more than a quarter of a kW to satisfy the full demand of the van's battery charger.
Buy a quiet machine or you will alienate even the most forgiving neighbours.
Thanks for the prompt replies.
The one I am looking at getting is a 4 stroke 1kw and would only be used as an emergency back up to my battery with solar panel used by day.
It is rated at 58db and I would only use it where and when it is allowed.

The Honda one is rated at 52db, is the extra 6db really that noticeable ?
I definitely do not want to offend anyone.
The db scale is not linear. Adding 4db doubles the noise level
A decent quality generator will set you back close to £1000. You can get cheap ones for £150 but they will blow your charger up eventually, mine also blew my TV up. You can get solar panels for around £1 per watt, so if you were to invest £200 in solar panels rather than a generator, you can be putting that power in throughout the day, silently and for free, rather than burning petrol, annoying the neighbours and sniffing fumes for a few hours.
If you haven't already done so, change your halogen bulbs for LEDs. We have managed for a week in summer with a 50 watt panel and an 85 aH battery with the battery still showing over 13 volts on our departure.
With solar power as cheap as it now is and LED lighting, generators are old news with caravanning.
As regards the noise, doubling the decibels increases the noise 10 times.100 decibels is considered to be enough to cause permanent hearing damage.

Why not use the generator under the bonnet of your tug !
Buy a second leisure battery and charge it up when you run around in the car, works a treat unless the tug is parked up most of the day.
.... and then just pray you are never involved in an accident with that second battery in the boot. I personally would not fancy the idea of being hit on the back of my head with a lump weighing 25kg travelling at 60mph.
If you are reasonably proficient at DIY a roof mounted solar panel is easy to fit and works even when the van is not in use. You can get a panel on eBay for roof mounting on the van and a regulator for a lot less than the Maplins kits. Brackets are overpriced but can be made with some aluminium angle off cuts.
It's not worth skimping on the cheapest regulators either as they can waste a lot of the power from the panel.
The 13 watt suitcase actually has a much bigger regulator than it needs

I am looking at this

What do you think?
I will be using it for other applications as well as the caravan so I need a portable kit.
Thanks
------------- Albino, Can"t say fairer than that !
The other advantage of a portable panel is weight. With a portable panel it does not have to travel in the caravan and will therefore save you 10kg to 15kg off the payload which if you already have movers fitted can be crucial. Last summer I was talking to a guy who had 120W panel on his roof but had not even thought about how it was going to reduce his payload and he suddenly had a mad panic realising he was well over weight with everything else he was lugging about.

and what's the weight of a generator ? My leisure battery is anchored with webbing straps
