I'm sorry, but I am sort of confused right now. I am looking for a way to power my Samsung notebook in UA business class.

Do I understand it correctly that the Kensington Inverter will provide me with a standard wall outlet? I could then just plug in my regular charger and would be ready to go?
If so, then why are you talking about device specific tips - wouldn't it be much easier to carry one universal inverter and be able to plug in the same chargers one uses at home than buying a special tip for every piece of hardware?
I am not criticizing, I just want to understand.
