Great reviews but no power for low power devices

I couldn't get this device to power anything. I bought because of the great reviews. For several weeks I have been trying to use this device to power low power products. I know for sure that the device itself is sending energy because my iPhone8plus detects it. Of course, it doesn't really power the iPhone8plus - that was honest advertising. I want to clarify that the ONLY purpose of connecting it to my iPhone8plus+ was to verify that the iPhone recognized the device and did so. My point isโ€ฆ

Pros
  • Solar and wind power
Cons
  • Useless features

Defective item or bad design?

I ordered one of these based on a review I read here on AMZ. This article promises a voltage of no more than 6V and a current of about 500+ mA. This charges most items I was hoping to use it with and to some extent meets the USB 2.0 performance specification. Unfortunately, this article did not work. When plugged directly into the sun it didn't charge my backup battery or any other product I plugged it into (Note: I haven't tried a cellphone because I think the listing says it does will notโ€ฆ

Pros
  • solar panels
Cons
  • There are other interesting options.

Charging my AA NiMH batteries

I'm putting together a small row of solar panels to charge my AA batteries. I live in Florida, where weather can cause power outages. The last time a hurricane disrupted our power, I noticed my neighbor charging his phone in his SUV. You don't want to waste gas after a hurricane. My current setup consists of three Sunnytechยฎ 3.5W 6V USB mini solar panels (connected in parallel to keep the voltage at 6V) and four rechargeable 2400mAh AA NiMH batteries. I removed the USB connector from the boardโ€ฆ

Pros
  • Generators and portable power supplies
Cons
  • Everything is fine
