EcoFlow DELTA 2 Portable Power Station
Pros
- 1024Wh capacity and 1800W output define the modern home-essentials starter tier

- Expansion battery support gives it a growth path many 768Wh stations lack

Our Verdicts
BLUETTI AC70 Portable Power Station
The AC70 is the value pick for buyers stepping beyond electronics-only backup. It gives enough capacity and output for real essentials planning, with unusually strong solar input for the tier.
EcoFlow DELTA 2 Portable Power Station
The DELTA 2 remains a canonical 1kWh comparison point. It is a good essentials station if discounted, but the DELTA 3 Plus is the sharper EcoFlow pick when prices are close.
