Cons
- Newer DELTA 3 Plus improves solar input and surge behavior
- 27 lb weight is manageable but no longer casual
- One kilowatt-hour can still be marginal for refrigerators, CPAP, and router together overnight

Pros
- 2048Wh LiFePO4 capacity at aggressive value pricing
- 2500W output and high surge spec compete with more expensive 2kWh stations

Our Verdicts
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.
OUPES Mega 2 Pro Portable Power Station
Mega 2 Pro is the 2kWh value challenger. It can make the math work beautifully, but verify the exact Amazon variant and seller before making it the core of an outage plan.
