Our Verdicts
EcoFlow DELTA 2 Max Portable Power Station
DELTA 2 Max is the 2kWh solar-friendly value anchor. It is one of the cleanest buys for fridge/router/lights planning when you also want expansion room.
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.
