Review on πŸ”Œ WOLFWILL Solar Panel DC 5.5mm x 2.1mm Adapter Cable - Universal Charge Connector for Power Solar Panels and Portable Solar Generator Inverters by Dan Reggae

Revainrating 1 out of 5

Reverse polarity! Best in Generators and Portable Power Supplies

As previously mentioned the polarity of this cable is REVERSE. The red wire (positive) connects to the outside of the chassis connector and the black wire (negative) connects to the center of the chassis connector, which in most cases is the reverse of how it should be connected. I'm not aware of any application of this reverse polarity design, so to my knowledge it's a defective cable! Rather than going back I decided to cut and beef up the wires while maintaining correct polarity.

Pros
  • GOLS Certified
Cons
  • Not Reliable
