iGreely SAE Plug to DC 5.5mm x 2.1mm Male Cables with SAE Polarity Reverse and DC 8mm Adapter for Automotive RV Solar Panel 14AWG 2ft/60cm

Heavy duty. Works with the BougeRV coolers.

Worked great

Good and sturdy--and I like having the polarity inverter if ever necessary.

Works well with yeti 400 5 mm to 8 mm adapter you can use harbor freight solar panels to charge. Also charged from 3/4 to full charge in less than 4 hrs

Male Pin wouldnt fit into female socket, too large a diameter!
