*Calculated at a constant 1000W AC load, 85% efficiency, 10% reserve and 8W battery-side idle draw for both models. Equal assumptions for comparison, not measured efficiencies. A dash means the value was not clearly stated on the manufacturer's page when checked.

Quick answer: The EcoFlow DELTA Pro 3 has 256Wh more nominal capacity (4,096Wh vs. 3,840Wh); the Anker SOLIX F3800 Plus lists more continuous AC output (6,000W vs. 4,000W); the EcoFlow DELTA Pro 3 is lighter (113.54 lb vs. 136.7 lb). At a steady 1000W load our model estimates 3.1 h for the EcoFlow DELTA Pro 3 and 2.9 h for the Anker F3800 Plus. There is no universal winner: your loads, charging plan and the price of equivalent bundles decide.

Where they differ

Choose the EcoFlow DELTA Pro 3 if…

  • you want more stored energy (256Wh more)
  • weight matters when you move it (23.2 lb lighter)
  • energy per kilogram matters to you
  • you start motors or compressors (surge 8,000W published)
  • you want more AC outlets (7)
  • you use it as a UPS for sensitive equipment (10 ms switchover)

Choose the Anker SOLIX F3800 Plus if…

  • you need to run heavier loads at once (6,000W continuous)
  • you plan to recharge from solar (3,200W max input vs. 2,600W)

Read the cycle ratings carefully

The two manufacturers do not rate battery life to the same end point: EcoFlow DELTA Pro 3 states 4,000 to 80%, Anker SOLIX F3800 Plus states 3,000+ (end point not stated). A rating to 70% remaining capacity is not directly comparable with one to 80%.

Notes from the manufacturer pages

  • EcoFlow DELTA Pro 3: 120V/240V output. 6,000W with X-Boost for suitable loads.
  • Anker SOLIX F3800 Plus: 120V/240V output. Cycle rating listed as 3,000+ without an end-of-life percentage.

Check your own loads

Capacity decides how long; continuous output decides what can run at once; surge decides whether motors and compressors start. Put your appliances into the tools below with either model preselected, and compare delivered prices for equivalent bundles before you buy.
