Are the front and trunk 12v socket the same power? 

I would imagine so since they both say 12v on.....

You have either answered yourself with your own question or your question could be better phrased.

The other day I tried plugging my mobile car vacuum cleaner in the 12v socket in the boot and it seem to me like it was not running as powerful as when I was plugging it in the front socket.

12v <-- in fact this doesn't measure power. The two sockets could give different Amperes, which would give different Watts (power, W = V · A). 

 

Think of the charger of an iPhone and an iPad. The iPad's charger is more than twice the power of the iPhone's, but since they're USB they have the same voltage (5V). If you hook the iPhone to the iPad's charger, it charges faster.

 

With that said, I'm also curious to know if some has checked for any difference between the two sockets.
