The table below summarises the plug types, voltage and frequency of electrical current in both Mexico and Guatemala.
| Mexico | Guatemala | |
|---|---|---|
| Plug Types | A | A, B, G, I |
| Voltage | 127V | 120V |
| Frequency of electrical current | 60Hz | 60Hz |
Mexico uses Plug Type A.
In Guatemala there's more than one socket type in use. You may require more than one adaptor.
Socket Type A
(Mexico) to Plug Type B
(Guatemala)
Socket Type A
(Mexico) to Plug Type G
(Guatemala)
Socket Type A
(Mexico) to Plug Type I
(Guatemala)
Guatemala also uses Socket Type A, which is used in Mexico. If using an appliance that has a Type A Plug in the Type A Sockets of Guatemala, you will not need an adaptor.
The voltages found in Mexico (127V) and Guatemala (120V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Mexico and Guatemala is exactly the same (60Hz). Timing devices and appliances that use motors will function as expected under this frequency.
