I ordered some of these as Christmas presents this year. I tested them. They work.
"Solar Battery Charger AA AAA C and D
Our solar battery charger is a simple way to keep your Ni-MH or Ni-CAD batteries charged. Compatible with all sizes (AAA,AA,C and D). Simply insert the batteries and put the solar charger into the sunlight.
Batteries not included (but I'm adding them to the gifts).
At these (retail) prices, $5 or 6 billion buys entry level electricity for the poorest billion people in the world - solar energy for light, communications, and battery charging. This is also survival solar, what we are supposed to have on hand in case of emergency or disaster.
Combining even this miniscule amount of solar with bicycles as both small generators and batteries, from AAs on down and on up through 6 volts, 12 volts all the way to the grid, an individual could conceivably have access to bare minimum electricity almost all the time in almost any situation. Looked at from this direction, bicycles, e-bikes, and the varieties of other new personal mobility devices as well as electric vehicles could be seen as a floating network of power producers and consumers* at the same time, mobile energy storage and generation.
This is one reason why I say Solar IS Civil Defense.
We would do well to prepare for the next weather event in ways that mitigate as well as adapt to the already occurring climate changes. We may need it quicker than we think.
* This energy consumer/producer concept is also happening in our buildings as net zero energy building codes are adopted.

We remain alert so as not to get run down, but it turns out you only have to hop a few feet to one side and the whole huge machinery rolls by, not seeing you at all.
