At a Glance
This comparison targets buyers weighing a high-capacity whole-home backup station against a lighter, more portable unit. The Anker SOLIX F3800 delivers 6,000W of running power and 3,840 Wh of capacity, nearly quadrupling the DELTA 3 Plus on both counts.
That muscle translates directly to device coverage: the F3800 powered 52 out of 53 tested devices, while the DELTA 3 Plus handled 42. Surge capacity tells a similar story, with the F3800 reaching 9,000W versus 3,600W for the DELTA 3 Plus, giving it a clear edge for starting heavy appliances like air conditioners or well pumps.
The tradeoff is significant, though. At 132.3 lbs, the F3800 is nearly five times heavier than the 27.6 lb DELTA 3 Plus, making the EcoFlow unit far easier to move between rooms, load into a vehicle, or carry to a campsite.
