The Only Travel Adapter You’ll Need in Interlaken

Already traveling or just arrived and forgot your power adapter? It happens, and you’ll likely find one locally. But when you bring a trusted one from home, you know it’s the right fit, safe to use, and won’t let you down.
Interlaken travelers often explore neighboring countries like Italy, Germany, or France. Plug types may vary, so double-check before packing.
Do You Need a Voltage Converter?
Since Interlaken has a different voltage than the U.S. (120V), you’ll probably need a voltage converter to keep your devices running smoothly.
Always verify the power rating label on your device before plugging it in overseas. If it lists “100-240V, 50/60 Hz”, it’s built for global use and works on both 120V and 220-240V without needing a converter. Most modern electronics, like laptops, tablets, and cameras, support this.
