What do your outlets look like over there? I'll be in london next week and I want to make sure I'm getting the right adapter.

The one I bought has two round plugs, same size, accepting 220v, but I have also seen the chunky three prong plugs. I will probably only be in lower England if that makes a difference.

Here (USA) we have 3 types:

unpolarized (two flat connectors of equal size)
polarized (two flat connectors, one wider)
grounded (two flat connectors, one wider, plus a round ground wire pin/plug).

You can plug an unpolarized plug into any socket, but not the other way around. All are 110-115 volts. Do you guys have equivalents for these?
