Category Scores
Capacity
The EcoFlow DELTA Pro 3 and Anker SOLIX F3800 Plus are level here, at 9.5/10 each. usable watt-hours and how long it runs real appliances is not what separates these two — look to the categories where the scores diverge.
Output Power
The Anker SOLIX F3800 Plus is marginally ahead, 10.0 to 9.8. A gap this small rarely decides a purchase on its own, though it counts if continuous AC output and whether the surge rating is genuine is your priority.

- +Its price has fallen roughly $900 from launch
Cons
- −113.5lb — it has wheels for a reason, and it is not going camping
- −The 6,000W X-Boost figure is voltage reduction, not true surge
- −Only two USB-C and two USB-A ports on a station this size
- −Full system expansion runs into five figures quickly
