Electrical systems vary worldwide; many countries use unique plug shapes and operate on 110 to 240 volts. Check your destination's specifications and your devices’ voltage compatibility. Using devices with incompatible voltage without converters can damage them. Universal plug adapters let you connect to various outlet types. Carry spare adapters as a backup. Proper electrical preparation enables safe charging of phones, cameras, laptops, and other essentials, preventing inconvenient outages or damage.
