TV Charger
One of the worst things about traveling is that power outlets vary from country to country. You’re probably used to the two-pronged outlet in the United States, but if you visit a place like Indonesia, you’ll have to pick up an adaptor since their two prongs are circular, not rectangular.
However, USB ports are universal. That’s why you should check your hotel room’s TV to see whether it has any extra USB ports. You can plug in your devices and charge them directly from the TV. This will also come in handy at airports when there aren’t enough charging ports.
