Test solar charger
I'am not a worker who is in workshop. What I should do--answer questions(to customers), deal with orders, place MO. Moreover, testing samples and recording data.
Yesterdays, I test a small solar panel what is customized for charging cellphone. First characteristic is USB outlet, and second is 5V(10 cells in series).

It can provide small power, only 3W. Perhaps it is suited to non-smartphone, in other words, a cellphone with small battery, such as classic Nokia, who's battery is only hundreds mAh.
