Capacity
DELTA 3 Plus: +755 Wh (+281.0%).
This comparison targets buyers choosing between a compact backup unit and a mid-size portable power station. The DELTA 3 Plus 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 clearly in device coverage: the DELTA 3 Plus powered 42 out of 53 tested devices, while the EB3A handled just 21. EcoFlow's station also accepts up to 1,000W of solar input and supports battery expansion, making it far more versatile for home backup or extended off-grid use.
The tradeoff is size and portability. At 10.1 lbs, the EB3A is less than half the DELTA 3 Plus's 27.6 lbs, which matters if you need a grab-and-go kit for short trips or light electronics.
