Review on 🔌 iGreely 10AWG SAE Extension Cable - Quick Disconnect Wire Harness with SAE Connector - Solar Panel Extension Cable for Automotive, RV, Battery, Motorcycle, Cars, Tractor - 10 Gauge, 1M (3Ft) by Robert Grind

This is a thick and stiff cable which may limit some uses. Some reviewers claim that the wire is aluminum and not tinned copper. Maybe they have a different cable, but I have a copper cable. How should I know? Checking the weight per foot. The cable precisely meets US specifications for copper wire weight per foot. Aluminum is three times lighter, there is no room for error.
