This topic comes up every once in a while in other threads but not discussed on its own.
A number of people got GMRS, and or Ham, radios for use during an emergency but haven't given much thought to how the radio(s) will be powered once the battery pack is dead, for portables, and how to recharge them.
For an extended power outage, over a large area, gas powered generators likely won't work for long due to the fact the gas pumps likely won't have power either to refill the gas cans. One case in point was the great northeast power blackout in 2003.
I'm in the Detroit area and the gas stations had no power except for a few. Those were only pumping gas for police, fire etc. nothing for anybody else.
One solution is using a small solar power system to keep a battery charged up. There are plans all over the Internet for building "solar power generators" with one example below.
Some of the info above is out of date, but the general idea of how to build one isn't.
So what plans have people made to power their radio equipment when the grid goes down?
