Capacity
Anker SOLIX F3800: +1,792 Wh (+87.5%).
This comparison targets buyers choosing between a high-capacity home backup station and a lighter, more portable alternative. The Anker SOLIX F3800 delivers 6,000W of running power and 3,840 Wh of capacity, more than doubling the DELTA 2 Max's 2,400W output and 2,048 Wh battery. That gap shows up in device coverage: the F3800 powered 52 out of 53 tested devices, while the DELTA 2 Max handled 45 of 53.
Both units use LFP chemistry rated for 3,000 cycles, and both are expandable. The tradeoff is size and weight. At 132.3 lbs, the F3800 is nearly 2.6 times heavier than the 50.7 lb DELTA 2 Max, making the EcoFlow unit far easier to move between rooms, load into a vehicle, or carry to a campsite.
Solar input capacity also differs significantly: 2,400W max for the Anker versus 1,000W for EcoFlow.
