I have a dual voltage laptop, which I am about to bring to Russia. The thing is, I'm not quite sure which adapter to use. I went to the travel store today & I saw two adapters that were almost identical. The employees didn't know the difference between the two, so I bought both. The first is a "grounded adapter plug" & the second is an "adapter plug":
They're both for a three pronged plug, which I need for my three-pronged laptop plug. Besides that, I can only find four differences between the two:


They're both for a three pronged plug, which I need for my three-pronged laptop plug. Besides that, I can only find four differences between the two:
- The first pic has the word "grounded" in the title. What does that mean, lol?
- The first pic has metallic sections to the top and bottom of the part that plugs into the wall.
- The section of the adapter in the first pic that plugs into the wall is rounded. This can be important as I know from past experience that Russian outlets are sometimes in an indented hole.
- You can't tell from the pic, but it appears that the two prongs on the adapter in the first pic are slightly bigger than the one on the right.
