The Sandberg Survivor Radio All-in-1 5000 is a compact, robust device with lots of smart features, all of which can be useful in nature or even in an emergency. You get a power bank to charge your smartphone, a Bluetooth speaker, a radio with both AM and FM reception, as well as light functions that serve as a flashlight and reading light. You can charge the device from a conventional USB power source, but in the absence of a power source, you can use the built-in solar panel and the associated crank for emergency charging.
