My wife bought one that works on several different plug styles, but not as sturdy as this one. Both worked fine for our London trip, but note these DO NOT convert the voltage to 120 VAC. The USB adapters do work fine and my other chargers work on any voltage between 110 to 240 so I was covered. This is a bit more bulky than my wife's since her pins all retract into the adapter, but as I mentioned it is much sturdier. I felt more confident using this adapter.
