Guamanian power outlet

Varying different combinations of voltages and standards can often be confusing when planning to travel to a different country if you've never visited before. This guide was specifically written to stop you needing to worry if you'll be able to charge your mobile phone when you are staying abroad.This page has useful instructions showing exactly how to power the mobile phone when travelling to Guam by using the standard types B or A Guamanian 110 volt 60Hz wall outlets. If the mobile phone slowly recharges or doesn't turn on when you are visiting Guam from a different country check that it is compatible with a 110 volt power supply. Devices which come from another country which use a higher voltage (for example 220 volts) can take longer to charge or won't power up, so check that the mobile phone is a dual voltage device (normally marked with a 100-240 volt notation) otherwise you may need to use an additional voltage converter to ensure proper use.

These instructions are for a generic mobile phone and assume the phone has a standard micro USB port, Bluetooth connectivity and a headphone socket. For a specific mobile phone visit the Mobile phones page for a full list of makes and models.
