Pros & Cons
EcoFlow DELTA Pro 3
Pros
- +240V output through an L14-30R means it can genuinely back-feed a house transfer switch, which almost nothing else here can
- +Expandable to 48kWh as a full system — this is whole-home territory
- +2,600W of solar input across dual MPPT
- +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
Anker SOLIX C1000 Gen 2
Pros
- +2,000W continuous with a genuine 3,000W surge is the strongest real output at 1kWh here
- +49 minutes to full is the fastest recharge of any station in this list
- +Five AC outlets and two 140W USB-C ports
- +Routinely discounted to around half its list price
Cons
- −Gen 2 deliberately removed battery expansion — if you want the add-on pack you need the Gen 1 C1000 or C1000X instead, which is easy to get wrong when both are listed
- −Only 12W from the single USB-A port
- −600W solar is good but well behind the EcoFlow's 1,000W
