I am currently in Japan and will be receiving a new laptop from America within a few weeks. I currently have a surge protector from America and a Japanese to America voltage converter. Due to the shape of the plugs, I must plug the voltage converter into the wall first, and then attach the surge protector to it. Is this setup safe for my computer, or should I go buy a Japanese surge protector? This would allow me to plug the surge protector into the wall and then attach the voltage converter to it.
In case anyone is wondering, the voltage converter really isn't much more than an American 2 prong to 2 prong + ground rod converter (I am sorry for this description; I do not know the real names for these types of plugs/outlets). The wall outlets here are the same as American outlets, but they do not have a third hole for a grounding prong. Also, the voltage in Japan seems to only differ from American voltage by 10v or so.
