| Dominican Republic | El Salvador | |
|---|---|---|
| Plug Types | A | A, G, I, J, L |
| Voltage | 110V | 115V |
| Frequency of electrical current | 60Hz | 60Hz |
Dominican Republic uses Plug Type A.
In El Salvador there's more than one socket type in use. You may require more than one adaptor.
Socket Type A
(Dominican Republic) to Plug Type G
(El Salvador)
Socket Type A
(Dominican Republic) to Plug Type I

(El Salvador)
El Salvador also uses Socket Type A, which is used in Dominican Republic. If using an appliance that has a Type A Plug in the Type A Sockets of El Salvador, you will not need an adaptor.
The voltages found in Dominican Republic (110V) and El Salvador (115V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Dominican Republic and El Salvador is exactly the same (60Hz). Timing devices and appliances that use motors will function as expected under this frequency.
