How can you communicate when there is no electricity?

In order to communicate on amateur radio even when there is no power available from the network, you can use battery-operated radios. Solar panels or hand-cranked generators can also be used to generate the energy needed. Furthermore, in the area of ​​amateur radio, mobile transceivers are available that can be connected to the cigarette lighter in the car to enable operation via the vehicle battery. Building a self-sufficient system with a combination of battery bank, solar cells and wind power is also an option for long-term independence from the power supply.
