At a Glance
This comparison targets buyers choosing between a compact, ultralight backup unit and a full-size portable power station with serious home-backup muscle. The DELTA (Gen 1) from EcoFlow delivers 1,800W of running power and 1,260 Wh of capacity, nearly five times the stored energy of the Bluetti EB3A's 268.8 Wh pack.
In device compatibility testing across 53 appliances, the DELTA powered 40 while the EB3A handled 21, giving EcoFlow's unit a clear edge for households running higher-draw tools or kitchen appliances. Solar input tells a similar story: the DELTA accepts up to 400W and works with 19 compatible panels versus 200W and six panels for the EB3A.
The tradeoff is weight and longevity. At 10.1 lbs, the EB3A is roughly a third the weight of the 30.9 lb DELTA, and its LFP chemistry is rated for 2,500 cycles compared to 800 for the DELTA's NMC cells.
