HI Doppy!

Thank you for your post. I checked the adapter that came with my HP, and the plug from the wall fits into a large adapter, which then plugs into my computer to charge it. The only thing I can read on the adapter is it is made in China, but the plug from the wall says "125V". So, I'm assuming it's a step-down adapter (to 120V), but maybe I could use this with a foriegn plug adapter for a 240V step-up at the wall? Thanks for your help.
