At a Glance
This comparison targets buyers choosing between a mid-size portable unit and a high-capacity home backup system. The Pecron E3600LFP delivers 3600W of running power and 3072 Wh of capacity, tripling the DELTA 2's 1800W output and 1024 Wh reserve. That extra muscle lets it power 47 out of 53 tested devices compared to 39 for the DELTA 2, and its 7000W surge rating handles heavy startup loads from tools or appliances.
Solar input tells a similar story: the E3600LFP accepts up to 2400W, nearly five times the DELTA 2's 500W max, though a full solar charge still takes 5.5 hours versus 3.7. Built-in UPS with 20ms switchover adds another layer of utility for home backup. The tradeoff is weight.
At 79.4 lbs the Pecron is three times heavier than the 26.5 lb DELTA 2, making grab-and-go portability a clear win for EcoFlow's unit.
