Which Inverter/Generator ?

I'd agree with Pete C, even a low power caravan kettle is going to be 1kw.
If you can use gas for a kettle, everything else should be fine on 12v.
As for coolers, 12v is possiblebbut they are reportedly quite power hungry. Have a look here :

Wanting an inverter for a kettle and phone charging is like walking into a tool-shop and asking
for a hammer. "Whats it for?" "oh just demolition and panel pins"...

In calculating the loads for my new van install, I am a bit perplexed by how inverters are rated. I think I know the correct answer but would appreciate some validation from some more experienced minds.
The inverter I am considering the Victron Phoenix 12/375, a 300W inverter. It is my understanding that a 4mm2 cable with a 30A fuse should be sufficient, however, the peak power of the inverter is 700W...
I am assuming however that a 70A fuse (& cable) is not required, as the internal (non-replaceable) fuse in this inverter is only rated to 40A. I expect this is due to using 'slow' fuses which can handle a brief surge to a higher current.
As you can see, I am making a number of assumptions here. I have scoured the Victron wiring documentation, but the only diagram I found with the 12/375 inverter does not list the rating of the fuse or cable.

You are correct in your first assumption. Also the length of the cable has a bearing on its current carrying capacity. You can also use a 30A resettable fuse and this allows you have a safer lower rating.
Circuit breakers are often better than fuses in these circumstances as the “slowness” can be chosen.

Dont know if you may be able to help please @Dellmassive or @Deaky with this scenario....I know its probably in the wrong forum thread soz, Cheers.
You absolutely can’t run it from the cig lighter. A very rough calculation 1200w is 100 amps 12v. Add in the inefficiency of the inverter and its probably more.

Thanks @Deaky ,ill have a read. Probably a bit of an optimistic/stupid question in hindsight, so I think it would be sensible to just run it when hooked up to 240.
Definitely.
I run a 1200W Tassimo from a 3000W inverter connected to my leisure battery and it works fine. The only issue is if used with an AGM (as I was) it really thumps the battery and you won't get more than 2 cups without giving it a good charge. You also need meaty cables, I used 25mm2, and plugging into the cig lighter, or using it from your starter battery is a no-no. I've got lithium now so expect to get coffee at will
Apologies for appearing 'Dim' on this.
What make of inverter did you use and what other bits would I need please...soz but a bit dim on this subject matter. Thank you....all in the name of decent coffee though!
Hi @andys.....so been thinking.....what kind of job would it be to connect a 3000w inverter to my lithium leisure battery in order to get 'coffee at will'?I run a 1200W Tassimo from a 3000W inverter connected to my leisure battery and it works fine.

Bestek do some nice cheaper ones. 100-300w
500w up mark you have some nice pro options.
Victron

Hi
Riese & Muller Tinker Vario Bosch motor/500w battery
I had the Victron 350w installed, works fine. Takes very little out of my Li-ion Leisure batteries , charges as fast as it does at home, with very little draw on the batteries.
