Global Plugs is an online travel reference that helps people check whether their electrical plugs and appliances are compatible with power systems abroad. Its country-based checker compares plug types, voltage, and frequency, then explains whether travellers may need a travel adapter, a voltage converter, or both. Results are based on official plug and power specifications.

The site also provides information for browsing countries and plug types, along with a blog and frequently asked questions. Its guidance clarifies that adapters change a plug’s physical shape to fit a socket, while converters adjust voltage for appliances that cannot handle the destination’s supply. It notes that many modern phone, tablet, and laptop chargers support a range of voltages, though a plug adapter may still be required. Older single-voltage devices, including some hair dryers and heating appliances, may need a converter.

Global Plugs also offers a free widget. Designed for straightforward trip planning, the service helps travellers understand electrical compatibility before they leave home.
