| Why pick it | More watts per dollar | More EcoFlow accessory path |
Pick F3800 if a well pump, a 240 V tool, or a larger window/portable AC is in the plan. 6 kW vs 4 kW is the whole review for a lot of houses.
Pick Delta Pro 3 if you already own EcoFlow extras or you know you will buy extra batteries and maybe a home panel in the same family. You are paying more for the ecosystem, not for more watts.
