A travel adapter is a device that allows you to connect your electronic devices to different types of electrical outlets found in various countries. Since plug shapes and socket designs vary worldwide, a travel adapter ensures that you can charge your devices, such as smartphones and laptops, while traveling. Most travel adapters do not convert voltage, so it's important to check if your device is compatible with the local voltage. Some adapters come with built-in USB ports, making it easier to charge multiple devices at once. Always choose a reliable adapter to ensure safety and efficiency during your travels.
