Dual lightning & 30pin USB cable

My wife has a 4 and me a 5. At the moment we charge both overnight and where we do its got one plug so is awkward.

I've had a look about and seen a USB cable with 1 USB plug and 2 cables coming out, one for lightning and 1 for 30pin.

Has anyone used one? Can recommend one? Can you charge both iPhones at same time from the standard charger that comes in iPhone 5 box? (Thinks its 1W?)

I'm in UK for reference for buying.
Cheers

Hm... why not buy a new charger?
Also, cant you use your own charger and your love use another one?
ITS SAFER!

Have loads of chargers now to be honest as also have iPad minis in house. The point is rather than having a big plug extension with 2 chargers in, was thinking of one of these dual cables just for neatness really.
