An outage that keeps the fridge cold and a campsite that keeps the lights on are different power jobs, and that is where portable power station vs inverter generator stops being a search phrase and starts being a real choice. This comparison uses one power station and two inverter generators, each only for what it publishes. The short verdict: the power station side suits silent, fuel-free backup with expandable capacity, while the inverter generator side suits long run times and refuelable power.

How we scored them
The Solar Score weighs performance, build, value, safety and warranty. For backup power, safety means a stated weather code or certification; no listing here states one, so the safety column is zero across the board. All three state a concrete warranty term: 5 year for the Jackery, 3-Year for the Champion and three-year for the WEN. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |

| WEN 3600W Inverter Generator | 9.4 | 27 | 19 | 21 | 0 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
