If you are planning on traveling abroad, and you want to bring electronics such as your laptop, battery charger, cell phone, etc, remember to buy some adapter plugs because they have differently-shaped outlets overseas.
Sometimes you will also need a converter as well, if the voltage is different - but most often you can get by with just an adapter.
If you're going to the UK or Europe, adapter plugs are almost always cheaper in the US than they are over there, so you'll save a few bucks by buying them beforehand!
