According to the third point, this flashlight should be with rechargeable battery and a real solar panel! The typical name of such flashlight is: Mini Solar Power 3 LED Lamp Flashlight Torch with Key Chain Free shipping ZH291. Typical cost about 1$-2$. I bought it only for 0.96$!
This is the device photo from Ali:
That is how it actually looks like.
Flashlight has light weight and very bright light. Ok. Let’s disassembling it! Ooh what a surprise!
Three white LEDs, button, Lithium battery CR2016 and something looks like a solar panel connected with …nothing. But when I separated the solar panel from the board, I defined that this solar panel was real, and it’s name: 3722-9L. (QF-3722-9L, output 4.5V and 10.0uA at 200 lux).
So, what we have in conclusion: plastic enclosure, three bright leds, lithium battery CR2016 and solar panel QF-3722-9L and all it for 1$! I think it is very good!
