Review on Solar 5 5Mmx2 1Mm 3 5X1 35Mm Rechargeable Generators by Robert Aan

The product came in the worst reverse polarity, be careful. Didn't bother sending it back, I'm only using it for testing as that was the main purpose. Switching the MC4 connectors from +- to -+ still didn't work with the connector you plug into the solar generator, two of which had to swap black to red and red to black for it to work properly. strange. Next time you just have to look at the right + - it's not correct. The solar panel I use is Lensun, they have MC4 connectors, both are black but they have labels that say +-. Also, the only copper in this 18 AWG is in DC mm and not MC4 - it's tin/aluminum (silver). Should really use 10 AWG if you're using MC4.
