MacBook Pro power cord

Hi,
I hope someone with experience can help me.
I bought a MacBook Pro an year ago in USA and I am now working in France.
I bought a plug adaptor for my power cord so it can plug into french sockets.

As you know in france the voltage is usually 250 volts, much higner than in USA which has 120 volts. my voltage adaptor works between 120-240 volts.
I am just wondering that 10 volts difference between the limit of my adaptor and the french voltage does put my Mac in danger?
thanks for your response

Doesn't France use the same 220-240V system used everywhere in Europe?
I've used a lot of devices in France, don't worry about it.
Where have you gotten this 250V idea, I've never heard of it?

Thanks Krisis1,
I guess I was mistaken. I got this idea from looking at the power control box at my appartment where there was indicated the max voltage 250 V.

I was worried about this because when i recharged the Mac, I could feel the tiny vibration on my Mac, I thought the Mac was telling me she was suffering from too high voltage
