EcoFlow DELTA 3 Plus vs Anker SOLIX F2600

Side-by-side on the specs that decide it — surge, capacity, runtime and price.

Both models' specs verified against manufacturer listings · Last updated

The short answer

EcoFlow DELTA 3 Plus costs $750 less. Whether that gap is worth closing depends on what you need to run.

EcoFlow DELTA 3 Plus

The DELTA 3 with a $100 premium for smart-home integration and faster UPS switching. Same battery, same surge.

Best for: Home-office setups where a desktop or NAS can't tolerate a power blip.

Where it falls short:

  • $100 more for features many buyers never use
  • Same 1024Wh as the cheaper DELTA 3
Anker SOLIX F2600

An odd spec sheet: 2560Wh of capacity but only 2800W surge — the lowest surge-to-capacity ratio here. Capacity without starting power.

Best for: Long-duration backup of steady loads (lights, electronics, CPAP) rather than motor-driven appliances.

Where it falls short:

  • 2800W surge is barely above its 2400W continuous — it will struggle with pumps
  • 61.7 lb
