I think they mean plugging your Li-ion charger into the 240v outlet not charging the Li-ion battery direct - surely that should not cause problems if it is a true pure sine wave output?
That's not the way I read it, as ANY battery charger could be plugged into the 240V outlet, why single out Li-Ion? why make it a feature of the advert?

Well
Here goes

We have an onboard gas generated generator

Not used much
But it's ours

It's there for emergencies

Very hot, the aircon works

And the hound from hell needs it

Very hot, I need it I don't do hot

You decide what's important

And take it from there

I have an Aldi generator badged as Wolf usedwith my Bailey motorhome on motorsport events to run microwave,charge battery before solar and watch 5 nations in a middle of a field in Shropshire with about 30 other people.
You never know when you need a generator and they work fine with motorhomes!!

I have to admit that I never opened the link and assumed (wrongly ) that it would be a cheap noisy thing.

It must be the cheapest Inverter Generator around and hopefully prices may come down generally.

We have a small Honda bought off e-Bay but have only used it twice.

I would not run the engine as Stanner suggests for several reasons;

it is VERY fuel inefficient and the leisure batteries only get charged once the vehicle battery is fully charged on many systems, that may take an hour or so - so you will be sat on tick over for an hour or so..... with the noise and expense that entails and the wear on the engine.....

when the engine is switched on our satellite system is shut down and stowed automatically, so once some charge is back in it must be restarted - which drains the battery still further....

a generator can be put a few metres from the MH, the engine cannot, so the noise may be much more of a problem for those inside the MH,

on our MH the 12v in the back switches off when the engine is started (UK regulations for NCC registration - grrr....), so with engine on, cannot watch any TV even f could keep satellite dish up.....

if that generator does what you MIGHT need at a reasonable cost, go for it, but use it to supply 240v to the MH EHU unit - the supply is better and uses existing components, the 12v charging system may not work so efficiently and may put excess current into the battery,

sadly Screwfix will not allow me to see the item so I cannot comment on it in any detail, but if it does what you want go for it and then resell it if you no longer need it...

Remember Jo Cox and what she stood for.

Any comments above are only MY OPINION and should be read as that.

Because builders are increasingly using Li-ion powered tools.?

Maybe I heard wrong but I'm sure I heard/read somewhere that things like Li-ion chargers are the most sensitive devices when it comes to sine wave purity. I know such devices don't like cheap inverters.

PS Look at the picture.............

Yes, I can see what you're getting at, just didn't register with me

I have seen this one and would appreciate comments or horror stories alike - as stated just need to keep the lights and TV going - no need for hair dryer or microwave !

Did you buy it? Have you tried it.

Answering your question. It would work and has good reviews.

My van is fitted with a high capacity alternator so charges my 110ah battery very quickly.

We toyed with a genie for Le Mans week, but decided just to run the van for an hour.

Despite what people suggest, they are commercial engines and designed for this.

The solar issue seems a better solution for long term battery health. But most trips I do are either a few days then move, or plugged into a campsite or a house.

Not read all the way through, but we used a solar panel 80W and 2 batteries for 5 days in the winter, couldn't see the next field let alone the sun, the batteries still charged and we ran John's CPAP via inverter for 6-7 hours each night.
Just a thought hope he doesn't ant a gennie now we have a garage to carry one in.
