I'm in the UK and have been using a converter for my laptop. But I was talking to another student who is studying abroad with me and they said that the cord on my HP says it works for a wide range (100v-240v) and that I should be able to just get an adapter and plug it into the wall.

I'd like to do this as it'd make my charging situation much simpler, but I can't seem to find any documentation other than what it says on my (apparently converter) box part of the cord. Does anyone know if this is safe?
