At a Glance
This comparison targets buyers weighing two high-capacity LFP portable power stations for whole-home backup and heavy-load scenarios. The Anker SOLIX F3800 delivers 6,000W of running power and 9,000W surge, nearly doubling the Delta Pro's 3,600W continuous and 7,200W surge output. That extra headroom matters for running multiple large appliances simultaneously.
In device compatibility testing across 53 products, the F3800 powered 52 while the Delta Pro handled 47, giving Anker a clear edge in real-world coverage. Both units are expandable and use LFP chemistry, but the Delta Pro earns 3,500 rated cycles versus 3,000 for the F3800, offering a longer projected cell lifespan. Portability is another consideration: the Delta Pro weighs 99.2 lbs compared to the F3800's 132.3 lbs, a 33-pound difference that adds up during transport.
Solar users should note the F3800 accepts up to 2,400W of panel input versus 1,600W for the Delta Pro.
