[Elecraft] X-Dragon 20W Solar Panel

[Fred Townsend]

David: You mean take out the batteries and charge them one at a time? I
don't think so.

The X-Dragon ads rate high on the snake oil scale. Note all ratings are max,
not typical. They say 5v / 2.4a. Don't assume you can ever get those
parameters at the same time. My guess it is 5V open circuit or 2.4 amps
short circuit. Note also they never indicate how long it takes to charge a
cell phone. They also proclaim high efficiency. How high is high? If you are
an ant everything is high. You can bet whatever they measure is figuratively
done while running downhill with the wind at your back.

There are appropriate  chargers out there. I would suggest a ham radio
knowledgeable seller like Buddy Pole.

Maybe charge your batteries to run the KX3.
