Capacity
Anker SOLIX F3800: +2,324 Wh (+153.3%).
This comparison targets buyers weighing a high-capacity whole-home backup unit against a lighter, more portable alternative. The Anker SOLIX F3800 delivers 6,000W of running power and 3,840 Wh of capacity, powering 52 out of 53 devices tested. The Yeti 1500X covers 43 of those same 53 devices with 2,000W output and 1,516 Wh of stored energy.
LFP chemistry gives the F3800 a 3,000-cycle lifespan, six times the Yeti's 500-cycle NMC rating, which matters for daily-use or long-term backup scenarios. Solar input follows the same pattern: the F3800 accepts up to 2,400W from panels, quadrupling the Yeti's 600W max. The tradeoff is weight and portability.
At 132.3 lbs, the F3800 is nearly three times heavier than the 45.6 lb Yeti 1500X, making the Goal Zero unit far easier to move between campsites, vehicles, or rooms.
