At a Glance
This comparison targets buyers shopping for a high-capacity LFP power station that can handle serious home backup loads or extended off-grid use. The Anker SOLIX F3800 delivers 6,000W of running power and 9,000W surge, nearly doubling the Yeti Pro 4000's 3,600W output and 7,200W surge. That gap matters for running multiple large appliances at once.
In device compatibility testing across 53 products, the F3800 powered 52, while the Yeti Pro 4000 handled 47. Both units use LFP chemistry and support battery expansion, but the Yeti Pro 4000 pulls ahead in longevity with 4,000 rated cycles versus 3,000 for the Anker. It also accepts up to 3,000W of solar input compared to 2,400W for the F3800, giving it a slight edge for larger panel arrays.
The tradeoff is clear: raw power and broader device support versus longer battery life and faster solar charging potential.
