Who wins on what

Ranked by what users actually praise

Overall Impression

Strong value and real-world capacity for storm and off-grid backup. Multiple owners used the F3600 during hurricanes (Milton, Helene) and storms, reporting 5 days of power and AC capacity tests around 91-92%. Buyers frequently mention getting it on sale for $999-$1299, calling it a better deal than EcoFlow Delta Pro or Bluetti EP500 Pro at similar capacity, with solar input up to 1500W reported by some users.

Expansion and solar charging work, but details are inconsistent and confusing. Only the Pro version supports battery expansion, which surprised several buyers of the non-Pro model. Users report running two expansion batteries with solar panels to power AC units and fridges successfully, but questions remain about cascade cable specs, DC brick charging methods, and whether third-party batteries can be added, suggesting documentation is thin.

Customer service and build quality complaints are a real concern. Several commenters, especially in Europe, describe customer service as nonexistent or unreachable, with one calling the company 'con people.' EU Schuko sockets reportedly soften and deform in heat above 30°C, and some units need a 24-48 hour slow charge to fix BMS cell-balancing errors, indicating firmware or QC inconsistency.
