The phrase refers to a charging device compatible with both a mobile telephone and the electrical standards of Switzerland. This typically involves a power adapter that can convert the voltage and frequency of Switzerland’s electrical grid (230V, 50Hz) to the voltage required by the phone, along with a plug configured for Swiss electrical outlets (Type C or Type J).
Having the appropriate charging equipment is crucial for uninterrupted communication and access to digital resources while traveling in Switzerland. Utilizing an incorrect adapter can result in damage to the phone or the electrical system, or simply prevent charging. The historical context involves the evolution of international travel and the need for standardized or adaptable charging solutions to accommodate diverse electrical systems worldwide.
