How do I use a clothes iron in Guam?

Guamanian power outlet

Summary

First check that your clothes iron can work in Guam:

If not then you can either:

  • Use a dual voltage travel iron [2] - you may still need an appropriate power adapter for Guam but these cheap lightweight accessories are designed specifically for travel.
  • Use a power converter (or voltage transformer) - you can then use your existing clothes iron and other applicances with a 110 volt Guamanian power outlet, however this is considerably heavier and more expensive than a dedicated travel clothes iron. A power converter changes the voltage but won't change the actual physical shape of the plug on your clothes iron to fit in the power outlet used in Guam, so please check that the voltage transformer comes with a suitable power adapter for Guam otherwise you will still need to bring a seperate power adapter. Note - your own domestic clothes iron might not be suited for travel and you could risk potential damage in your luggage. [7] [AD]
Warning: If your clothes iron won't handle the 110 volts used in Guam you run the risk of a blown fuse, damage to your clothes iron or even an electrical fire hazard. Prior to using your clothes iron in Guam please check the instruction manual to ensure safe operation.

Dual voltage travel irons

How can I tell if my clothes iron is dual voltage?

An easy way how to tell if your clothes iron supports a dual voltage power outlet is to look for either a sticker or numbers printed on the handle, base or the plug. This location might vary depending on the make or model of your clothes iron, it should also be written on the box. Some dual voltage clothes irons might change automatically, however other irons will feature a switch which allows you to change between different regions depending on which country you are in.

  • Single voltage might say a specific number - such as 110V. If this number matches the 110 volts used in Guam then you should be able to use your clothes iron with a Guamanian power outlet.
  • Single voltage might also have a small voltage range with a dash to accomodate small voltage fluctuations - such as 100-120V. If the 110 volts used in a Guamanian power outlet falls within the range shown on your clothes iron then you should be able to use it in Guam.
  • Dual voltage will typically say a large voltage range separated with a slash - such as 100/240V. Your clothes iron will be capable of being used in Guam or any other country if these numbers are shown.

Travelling to Guam with a clothes iron

Can a clothes iron go in my carry on luggage?

According to the TSA guidelines for clothes irons there are no restrictions when bringing a mains powered clothes iron in your hand luggage through airport security in the United States. The TSA also recommends that you should check that your airline who is flying you to Guam will allow clothes irons onboard and that it will fit in the overhead bin or underneath the seat of the airplane. The TSA also recommends wrapping wires tightly around electric items such as clothes irons. If you do intend to bring a fragile or expensive clothes iron in your hand held luggage then it is recommended to bring hard carry on luggage as this provides the greatest protection against bumps and knocks during transit.   [10] [11] [AD]
