Field notes
The use-case list turns different jobs into explicit constraints: van-life models need LiFePO4, at least 500 W solar input, and a weight of 45 lb or less; camping models are capped at 25 lb. The page reports 47 qualifying models for its CPAP criteria and 27 for its UPS switchover criterion. Its guides also distinguish UPS from EPS switching, rather than treating backup power as a single feature.
