Yes, it must be one of the best batteries.

Next week, I will test the powerfilm + battery system.  So, the next
month, I can report the outcomes.

I measured the weights. The weight of powerfilm with batteries was 169
grams, without battereis was 117 grams. It was reported that the  iPod
 was successfully recharged.

So maybe I can discharge it, charge it with the solar charger for a few hours, and then stick it into the fancy countertop charger to see how successful the solar charger was.
