Travel Plug Voltage 2026

Travel Plug Voltage Assistant is an offline power preparation tool for international travel, study abroad and business trips. Search by country or region to check plug types, voltage, frequency and common notes, then build your own device list before departure.

You can record chargers, hair dryers, cameras and other electronics, mark whether each item supports wide voltage, and create a checklist for adapters, charging cables and power accessories.

The app requires no login, no account registration and no internet connection. It does not collect user data. Your trips, device lists and checklists are stored locally on your device, making it suitable for travelers who want a simple tool they can buy once and use long term.
