Frequently Asked Questions

Do I need a voltage converter or just a plug adapter?
Check the label on your device or charger. If it says 'Input: 100-240V,' you only need a plug adapter. If it says '120V' only and you're going to a 220-240V country, you need a voltage converter. Most modern electronics (laptops, phones, cameras) are dual-voltage.
What devices need a voltage converter?
Hair dryers, curling irons, flat irons, electric razors (older models), and some older electronics often need converters. These heat-producing devices are usually NOT dual-voltage. It's often cheaper and easier to buy a local version at your destination.
What is the best universal travel adapter?
Look for a universal adapter that covers Types A, B, C, G, and I (covers 95% of countries). Good options include built-in USB ports for charging phones/tablets without a separate charger. Avoid cheap adapters; invest in one with surge protection.
