I’m just curious what the rationale is behind carrying an electric cook top rather than a small gas camping stove. You can get as big/beafy of one as you like and it still won’t come in at 14lbs even with fuel. There’s a Coleman burner that goes on a cheap $4 propane tank that should easily get you through a week(I’d think), cost much less, weigh less, and not rely on you having an outlet within four feet. It’s practically a burner off of a gas stove, so I bet you could cook most anything on it.

Unfortunately I kinda doubt they have coleman tanks in Europe, but maybe? In any case, this is merely an example. Something like that will be cheaper, weigh less, be more flexible in use, and still allow you to cook with a fairly large pot.
