I bought this cable to link my Goal Zero Yeti 1250 to a 100Ah 12V lead acid battery, and it does exactly what it says. The bonded 4 AWG cable feels heavy and well made, and the 36 in length gives just enough slack in my setup. The SB175 high power port clicks in securely, and the battery clamps grip the terminals firmly. It's a simple accessory, not a magic upgrade, so expect longer run times only when you connect a suitable battery. Good, solid part for the Yeti 1250.
