In the event of a emergency, it is very important to be able to receive information from the authorities. A power outage may result in the media you use to reach news, no longer working.
When telephone, TV and internet are no longer available due to a power failure, radio is the best way to get information. Then it may be good to have a radio powered by alternative power sources such as battery, crank or solar cells.
The built-in battery is charged by a crank dynamo. The radio fits perfectly in the rescue box, boat, summer cottage or as a complement to the mountain hike.
A battery-powered radio may be preferable for most people. The downside is that you need to have batteries at home, which is a perishable product. It is also good to have rechargeable batteries that can be charged via a solar panel
A solar radio has a built-in battery, just like on the crank radio with the difference that the sun stands for the crank. You don't have to crank but need access to sun.
A radio with built-in powerbank that has both crank dynamo and solar cells. These are usually also able to be charged through USB and provide power through USB. It is also not uncommon for a led lamp to be built-in. Clearly a radio is preferable when the possibilities of charging are great
