At a Glance
This comparison targets buyers choosing between a compact, ultra-portable unit and a full-size home-ready power station. The DELTA 2 delivers 1,800W of running power and 1,024 Wh of capacity, tripling the EB3A's 600W output and nearly quadrupling its 268.8 Wh battery.
That gap shows up in real-world device coverage: the DELTA 2 powered 39 of 53 tested devices, while the EB3A handled 21. EcoFlow's station also accepts up to 500W of solar input and supports battery expansion, making it a stronger fit for overnight outages or multi-day off-grid trips.
Solar recharge on the EB3A tops out at 200W, yet it fills its smaller cell in roughly 2.4 hours. The tradeoff is size: at 10.1 lbs, the EB3A is less than half the DELTA 2's 26.5 lbs, a real advantage for day hikes, car camping, or grab-and-go kits.
