COMPATIBLE COUNTRIES: Package of 4 Travel Adapter plugs (Type B, C, I, L) for use in MOST countries in SOUTH AMERICA and NORTH AMERICA; Antigua, Argentina, Aruba, Bahamas, Barbados, Belize, Bermuda, Bolivia, Canada, Chile, Colombia, Costa Rica, Cuba, Dominican Republic, Ecuador, El Salvador, Guatemala, Haiti, Honduras, Jamaica, Mexico, Nicaragua, Panama, Paraguay, Peru, Puerto Rico, Suriname, Trinidad and Tobago, United States, Uruguay, Venezuela, Virgin Islands. DESIGN/FEATURES: The adapter has a built-in surge protector to safeguard electronics. The adapter has TWO electrical receptacle ports (outlets), allowing you to connect two electrical devices at the same time. The main outlet at the front is a universal receptacle that accepts all types of connectors (including: 2-Prong US "polarized", 3-Prong US grounded, European, UK, AUS and India plug standards, but does not fit the large South African plug). The second outlet at the top of the adapter accepts 2-Prong US plugs (polarized too) and European 2-Prong plugs. USE THE ADAPTER: Please Note! The adapter does not change the Voltage. Please check the voltage standard for the travel destination and use a Voltage converter with the adapter if needed. (Example, Europe uses mainly 230 Volts). Many electrical devices, such as AC/DC chargers for Laptops, cameras, etc., allow a multi range Voltage (110–240 Volts) and do not need a Voltage converter. Some electrical devices have a switch for either 120 or 230 Volts (remember to set it back!). Please check the specifications on your equipment. Powering a 120 Volts device with 230 Volts can destroy the equipment and cause fire.
