It is helpful to consider your likely needs in advance. If you will need to charge several items such as mobile phones, tablet computers, cameras etc., it may be worth bringing a multiple, preferably surge protected, outlet from your own country to avoid having to purchase several adapters, or to deal with a limited availability of wall sockets.

In most cases, if your equipment normally runs on a 110 volt, 60 HZ supply, you will additionally need a portable transformer.
