Paul, I am not sure what you are asking. The charger says that it will take 100-240v.input at 50/60Hz 150mA 9W
The output is 15V - 5.4Watts The range appears to be 1.5V/5.4W
I assume you are asking if you plan to travel overseas. I would imagine that a standard 240V adaptor would work fine.
If this doesn't answer your questions, please be more specific in what you ask and the reason for your question. That would help get your question answered more appropriately.
