A:AnswerYes, this will work for a laptop. i also used it for my curling irons and the heat was equivalent to me plugging it in directly to an electrical outlet in the US.
A:AnswerYou can charge multiple devices via a power strip, but this item is just an adapter which converts an outlet. The adapter itself does not support multiple devices.

A:AnswerThe only converter that I am aware of that will work is the DX-TADPCON. The only downside is that it can only be plugged in for 10 minutes at a time. I am not aware of a converter that does not have this restriction.
