If you need more than 12v go with the inverter, below that there will almost always be an in car converter/reducer.

No I'm not confused ,I merely left out the rectifier for the sake of simplicity ,I assumed that everyone would realise that vehicle systems run on DC .It is the inverter that produces the 240volt AC from the 12volt [rectified] DC.
Zenslo has hit the nail on the head and expressed the fundamentals far better than I ,
WAVE FORM IS IMPORTANT ,I once wrecked my camera batteries because I charged them using a modified wave form inverter ,rather than a pure sine wave inverter .
So my advice is charge from your vehicle's 12 volt supply if you can but if you can't find a 12volt charger for your appliance then use a sine wave inverter supplying 240v [or 110v if you are in N America ].
I live off the electricity power grid and use inverters and batteries everyday and believe it or not have learned a thing or two by experience.
And yes I know that you don't really need serious or silly electronic gizmos to travel ,but then you don't really need a vehicle either do you ?
