Review on 🔌 Optimized Lithium Yeti Car Charger by Goal Zero: Safely Charge a Goal Zero Yeti from a 12V Power Source with a 15A User Replaceable Fuse for Enhanced Protection and Efficiency by Philip Brianne

My truck (2019 Chevrolet Colorado ZR2) is equipped with a smart alternator that changes the output voltage from 11.5 to 14.9 depending on driving conditions. A wide range of. It drops below 12 volts to save fuel. In this case, the device stops charging. So while you were hoping to have a full charge when you headed to camp for the night, your Goal Zero-connected fridge used up most of its energy while it was running. Theoretically, the truck should have been charging all the time and could easily keep up with the refrigerator with 60 watts of continuous power at 5 amps. To be honest there should be a lower voltage threshold so the device doesn't shut down when the alternator voltage drops to save fuel. Curious if you have a smart generator? Your voltage will be high at first, around 14.4 and higher for a while to charge the starter battery, then lower the voltage down to 13.8 over time, and as you drive longer (several hours of driving or so), drops them down to 12V, and sometimes even lower. .
