Chapter 1: Understanding Travel Converters & Adapters
The Two-Second Summary: Adapters vs. Converters
Before any practical guidance is useful, you must be able to distinguish between the two core devices in this category. A plug adapter is a purely mechanical piece of plastic and metal. It changes the shape of your plug so it physically fits into a different socket. It does not change the electricity that flows through it. If your device is rated for the local voltage, an adapter is all you need.
A voltage converter is an active electrical device that transforms the incoming mains voltage to a different output voltage. It changes the electrical supply to match what your device expects. If your device is not rated for the local voltage, an adapter alone will destroy it. The distinction is not a formality; it is the difference between a successful power-up and a blown capacitor, a melted power supply, or a small fire.
Consider a concrete example. You are a photographer on an assignment in the United Kingdom. Your camera battery charger is rated for 100-240 volts AC, 50/60 Hz. The UK mains supply is 230 volts at 50 Hz. Because your charger is dual-voltage, it will operate perfectly with only a UK plug adapter. The charger itself converts the high mains voltage into the low DC voltage your battery needs. But if you were carrying a clothes iron rated only for 120 volts AC - a common item in US households - plugging it into
