Can someone check my thoughts and see if I am on the right track please.
I need to use my Ipad whilst away, so ...if I was somewhere without 240v mains supply, could I use a cigarette lighter socket, fed from the 12v battery ( with inline fuse ) to power it using an inverter ?

Something like this ?

12V Modified Sinewave 100W Inverter.

Then if I were to get a portable solar panel, what size would I need ?

From a non techy Grandad...Thanks for any replies.

Why convert to 240v? something like this has the same ends

I have that in the car and like to have a set for the caravan, so I guess that's easier. :)

Does anyone know if those cigarette lighter chargers will work alright with the 12v rectifìed supply provided by the Eriba mains unit?

You have confirmed what I tried to say ............... the poster above my post was asking if the supply ....... or some part ? of the supply was suitable for using to charge some other devices............. tablet, phone type presumably, I was reluctant to give advice on that for some of the reasons you mention ie voltage stability ac or dc hence my advice to use a mains charger where the plug has a lump on it which presumably has internal parts that provide the correct voltage and current needed.

Just to put your minds at rest the intention was to connect a double USB cigarette lighter type item directly to the leisure battery under the bench seat, with an inline fuse.
I am not sure what the electrics in my van are good enough for. it is my intention to ask somebody who knows, maybe hob or Pepe , to have a look at the Stratford meet. As a forewarning, in order to get the 12 V working in my caravan I have to reconnect the white 12 S lead, which I do not use it from the car, to its respective socket under the front of the caravan ! One does love quirkiness ...... not !

A couple of points re 12v dc
Firstly, on a normal car cigarette socket, the voltage would be around 12v with the engine stopped but more like 14v with the engine running.
Secondly, cheap inverters don't necessarily give a smooth ac current. It can be a bit spiky, more like square waves than sine waves.

I was wondering if these usb chargers would be ok on such a supply. I don't think that the Eriba rectifier for the water pumps has any fom of smoothing. It appears to come directly from the transformer via a couple of diodes.

I don't really understand why if you are on hook up you wish to tap into the mains transformed 12v supply when a mains charger will work from a 240 volt ac supply without any risk to the article being charged?

I was on a field last week without a mains supply and just thought that it would be easier to be able to charge the phone and Ipad without leaving them in the car. I intend to feed this usb socket directly from the 12v battery under the seat, not tap in anywhere else.

Just read the last post so apologies if I've missed something or it's been covered already!
I fitted one of these last year (not from 12v planet but they are readily available online) for charging phones/iPad and it has performed superbly. I wired it direct from the leisure battery with a suitable inline fuse.
