At a Glance
This comparison pairs two very different portable power stations: the Anker SOLIX F3800, a high-capacity home backup unit, against the EcoFlow DELTA 2, a lightweight option built for grab-and-go use. The gap in capability is significant. The F3800 delivers 6,000W of running power and 3,840 Wh of battery capacity, powering 52 out of 53 devices tested.
The DELTA 2 provides 1,800W and 1,024 Wh, covering 39 of those same devices. Solar input tells a similar story: the F3800 accepts up to 2,400W, nearly five times the DELTA 2's 500W max. Both use LFP chemistry rated for 3,000 cycles, and both are expandable.
The tradeoff is portability. At 132.3 lbs, the F3800 is essentially stationary once placed. The DELTA 2 weighs just 26.5 lbs, making it easy to move between rooms, vehicles, or campsites.
