Mains chargers are universal charging sources that can have any type of connector on the output, for example USB-A, USB-C, micro USB, but also Lightning or MagSafe connectors suitable for Apple. However, they always have a mains plug on the input.
You can use mains chargers to charge a wide range of devices, especially at home, on your desk in the office and anywhere within the reach of electricity.
When choosing a mains adapter, look primarily at its output power or current and also at the type of output plug and its shape. In fact, some Swissten AC adapters can also serve as a handy phone stand when charging.
