live in u.s do i need an electric converter when traveling to london, or uk?

Answer 1

it depends what electrical appliance you want to use. Most appliances in the US use 110 V so you will need a) a current converter to convert 110V to 220V and b) a plug adapter. However, most laptops, cell phone and camera battery chargers, etc. use a power unit that uses current between 100-240 V, so you would not need a converter, but simply a plug adapter to use it in the UK. Make sure you check first...I fried my new cell phone recently, thinking its charger could handle 220V like my old phone, but it did not!

Answer 2

Yes,
The electrical standard in Europe is 220 volts, not the 110 volts in the US. This voltage is delivered at 50 cycles in Europe and at 60 cycles in the US. This means that your US clocks won't work in Europe. Anything with a timing circuit will be off by a little each hour.

In Europe the plugs that fit into the wall are different. Instead of the normal flat prongs used in the use, with a polarized plug European devices don't have polarized plugs and the plug is round.
