lost my two post on mastodon, so... blackout experience - 1 everything should be charging, because never know when will be possible to do this next time. turned out, that antique VEF-202 wich is after rework powered by 2x18650 batteries very convenient to use. battery charge lasts for a long time, and radio allows you to receive distant stations - AM/SW your friend when mobile networks partially out of order, partially overwhelmed from too much connections and even FM-radios out of electricity.
