Cons
- 113.5 lb body is transportable only with planning
- Not a whole-home magic box; circuits, transfer hardware, and electricians still matter
- High price makes load planning mandatory before buying
OUPES Mega 2 Pro Portable Power Station
Pros
- 2048Wh LiFePO4 capacity at aggressive value pricing
- 2500W output and high surge spec compete with more expensive 2kWh stations

Our Verdicts
EcoFlow DELTA Pro 3 Portable Power Station
DELTA Pro 3 is the EcoFlow flagship for serious home and RV backup. Treat it as an expandable essentials system, not a casual portable station.
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.
