Review on Electop 15ft SAE Extension Cable with Quick Connect Disconnect, 14AWG Wire Harness for Automotive RV, Motorcycle, Solar Panel Battery Charging - SAE to SAE Cable with Dust Cap by Marc Cahoon

This is a simple SAE extension from China. I bought the cable based on the description stating the copper wire was tinned like ship wire. Tinned wire is more resistant to moisture and corrosion than untinned wire. I cut off the connector on one end as I didn't need it for my application and was surprised it wasn't actually tin wire. Other than that, it is what it is. I will look for another reputable seller that has the correct description.
