<\/span>What Does Dual Voltage Mean?<\/span><\/h2>\n <\/p>\n
Some electronics are designed so they can be used in different countries. This means they\u2019ll be labeled as \u201cdual voltage.\u201d Dual voltage electronics have two options: 110-120V and 220-240V. They are ideal for travel because they are safe to use at home and abroad, too.<\/span><\/p>\nSome electronics, such as newer Macbooks and iPhones have dual voltage that automatically adjust in their destination. <\/span>However, you may need to adjust the voltage manually by moving an external switch in certain items such as hair tools.<\/b><\/p>\nIf your device isn\u2019t dual voltage, you\u2019re better off leaving it at home. However, most modern devices such as phones and laptops already have a dual voltage capability built in.<\/span><\/p>\n
