With a travel adapter, you can charge your devices in over 150 countries without having to take a separate travel adapter with you for every destination. You can adjust these universal travel adapters with sliders, so it fits all sockets that you can run into during your vacation or business trip. When choosing a travel adapter, pay attention to the power. If you only want to charge your phone, a 20W travel adapter is enough. If you're also charging a small laptop, choose 45W. For a larger laptop, get a travel adapter of 65W or more.
