Traveling to other
countries will make you personally aware that the planet operates on
basically two different electrical systems. All electrical devices are
usually designed to operate on one or the other system. Besides
the world having two different electrical systems, there are multiple
plug types that have been devised to go with each system. The human
mind is never idle!
States and a few other countries operate on the 110V system. The
rest of the world uses the 220V system.
The resources below will take you directly to
worldwide electricity guides that will tell you the system and plug
types for each country of the world.

the voltage, hertz and amps of your electrical
devices. Many electrical devices, and most
electronic devices, such as tablets, laptops, and camera
and recorder chargers, electric shavers, etc., are
dual-voltage. This means they will operate on either
110V or 220V systems, the two voltage systems in common
use worldwide. Most electronic devices are
auto-dual-voltage and automatically change to the
correct voltage when you plug the device into a wall
Check to confirm whether your device has a dual-voltage
capability and, if so, is it automatic or does it
has a manual switch to set the voltage. Many
hairdryers still have a manual switch to switch between
110V and 220V. Make
sure you have switched it to the proper voltage before
you plug it in.
Take Along a Set of Adapter Plugs.

to both voltage systems (110V or 220V), you will likely
need a different adapter plug to be able to plug your
power cord into a wall outlet in a given country or

Remember you are on the Planet Earth and not on some
advanced planet with universal electricity.
Make sure your

always try out your
electrical cord plugs with any adapters or extension cords to
make sure everything is compatible. For example, not all

handy. See below.
It is better to use a
dual voltage appliance than to carry along an electrical converter.
Especially if it is just a hair dryer or travel iron.
Even with a
dual-voltage appliance, you will probably still need an adapter
plug. Buy a universal set of them to take along and not just ones
for specific countries. Or at least buy a set for a region (e.g.,

You will eventually encounter one of the
following conditions: The bathroom does not have an electrical outlet
at all. The bathroom has an electrical outlet but it is only for
electric shavers. If you plug your hair dryer in a bathroom outlet (on
high) you may overload the system and then lights out! The only mirror is not
in the bathroom but in another part of your hotel room (O.K., a 1%
possibility but it does happen.) Maybe the electrical
outlet you want to use isn't working.
