| Frequency of electrical current | 60Hz | 60Hz |
In American Samoa there's more than one plug type in use.
What type of plug does your appliance have?
In Guam there's more than one socket type in use.
You will need this adaptor:
Socket Type A
(American Samoa) to Plug Type B
(Guam)

(Guam)
The voltages found in American Samoa (120V) and Guam (110V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in American Samoa and Guam is exactly the same (60Hz). Timing devices and appliances that use motors will function as expected under this frequency.
