Most countries use a 220- to 240-volt current for electrical outlets (the U.S. has 110-volt outlets). First, we recommend that you examine your appliances to determine if they can be used with 220-240 volts. If the appliance can safely tolerate the higher voltage, you will require a plug adapter that will allow you to plug into a wall socket. If your appliance cannot handle the alternative power source, you can try a power converter. North America and Central American countries typically have 110-volt, type A prong outlets that do not need an adapter. However, they rarely have three pronged outlets, so if your appliance has three prongs, you will need an adapter. To be safe, you can purchase one adapter that can be used in multiple countries with multiple configurations.
