While cell phones, smart phones, tablets, digital cameras, etc., laptops, digital cameras etc. are dual voltage (for US and Europe) you will still need an adapter to plug into French outlets. It’s a good idea to bring several of these adapter plugs with you. And, make sure that you have all the cables for your electronic devices. The reason is pretty obvious: you can find replacements at any number of stores in Paris – FNAC and Surcouf to name but two – but why waste your time shopping for such uninteresting items? The same holds true for any electrical appliance you may need to bring – make sure that you’ve got a transformer that works in France (it will work in most countries on the continent but not in the UK which, of course, requires different plugs….).
