10W Portable Solar Panel Kit Dual DC 5V USB Charger Kit Solar Power Controller with Fans
A part of the review has been auto-translated.
ATTENTION: The description of this item is NOT correct, furthermore, it works perfectly in full sunlight. With some shade, or less bright sunlight, only 5-15% yield. The angle of incidence of the sunlight is also very important. This solar panel is at most 1W @ 5V and NOT 100W !!! It produce +/- 200mA - 5V = 1W !!! @595W/m2 - 71500lux (= full sunlight) Short Circuit Current = 222mA. !!! @595W/m2 - 71500lux (= full sunlight) If this assembly is used as intended, fan must run in bright sunlight, then this is a good purchase. If you want to use the solar panel to charge a Li-ION or LiPo battery, you have to be very patient.
Looks tiny :) I hope it will works as I expect.
The symbol is very small in the shadow and has no function when it is desireless. Only direct sunlight of about 90 degrees Celsius and it works excellently. For my worm box, it is sufficient for ventilation. I recommend adding a buffer capacitor in between so that the fan doesn't stop when a little cloud passes by during startup. The fan whizzes with about 6-8 volts in full sun. At 5 volts, it is very slow but powerful, and below that, it doesn't work anymore. With a 50V 1000 microfarad capacitor, the fan runs very weakly at 4.5 volts.
Received soon and all correct. I have tried it and it works very well. I bought it to avoid condensation on my little ship in my absence. Of course I doubt it's 100 w. But in daylight the fan rotates at full speed with a good draft of air. [In the picture I have placed an AA battery so that the dimensions are visible).
I made the attachment from the phone holder:) it's wiggling like crazy
Does not work
smaller than expected but works really well!
👍👍

I haven't tried it yet but it came quickly and exactly as advertised. :)
