The widest gap in our portable lineup: a 234-lb, 13,000-peak-watt house machine versus a one-person fridge-and-lights unit at 40% of the price. Almost nobody is genuinely torn between these two — figure out whether your outage plan is 'power the panel' or 'power the fridge' and the answer falls out.
Pick the DuroMax if…
- ✓Whole-panel 50A backup with central AC
- ✓Load math above 9,000 running watts
- ✓Fuel capacity for long runs matters
Pick the Champion if…
- ✓Cord backup for refrigeration and charging
- ✓Minimal budget, minimal storage space
- ✓You value portability over capacity
