At a Glance
This comparison targets buyers weighing a high-capacity 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, more than triple the DELTA's 1,800W and 1,260 Wh.
That advantage translates directly to device coverage: the F3800 powered 52 out of 53 tested devices, while the DELTA handled 40 out of 53. LFP chemistry gives the Anker unit 3,000 rated cycles versus 800 for the DELTA's NMC cells, and expandable battery support means you can scale storage over time.
Solar input caps at 2,400W on the F3800 compared to 400W on the DELTA, a significant gap for off-grid setups. The tradeoff is size: at 132.3 lbs, the F3800 is over four times the DELTA's 30.9 lbs, making the EcoFlow unit far easier to move between sites.
