I saw in your video that supercapacitors can be better than batteries to store energy and thus power electronic devices. Can I use one to power my radio?
The biggest problem is with the charge circuit, which must be assembled. A voltage regulating circuit must also be provided, since the discharge curve of a supercapacitor is different from that of a regular battery. In addition, supercapacitors are currently expensive. Once these problems are solved, replacement is possible.
