Do I have have to have a voltage adapter as well as a plug adapter to use my laptop in the USA?
I purchased the computer while on vacation in the UK and will be bringing it home to the US. I have a plug adapter, but it does not convert voltage. Do I need to buy the expensive world adapters that also convert voltage, or will just a plug adapter work fine?

Answer 1 :
most consumer electronics in this day and age already come with an adapter that works with both 120V and 220V. To make sure, you should just read the adapter and it will say something like "Input: 110-220V"
Answer 2 :
Look closely at the fine print on your laptop's power brick. It will almost certainly say something like "Input: 100-240V, 50-60 Hz" This means anything from 100 to 240 volts, and anything from 50 to 60 Hertz AC. Which means that yes, you can power it directly from North American wall sockets without a voltage adapter (i.e. a transformer). All you need is the plug adapter. It's a lot easier for laptop makers to build these universal power supplies than it is to build and stock different supplies for different countries. This way the only thing they have to change is the cordset. I and many other travelers do it the other way all the time. My US-bought laptop works fine with just plug adapters all over the world. btw, in case you were wondering, the "100 volts" as a possible input voltage is for Japan - normal wall socket current in Japan is just 100V.
Answer 3 :
Chances are you won't even need an adapter. The power adapter for the computer likely uses a standard IEC type power cable, which you can get in the USA when you get there, or if you are like me, have a box of them.
