EcoFlow DELTA 2 Max vs DELTA 3 Plus — 2 kWh portable vs next-gen 1 kWh mid
DELTA 2 Max (~2 kWh class) versus DELTA 3 / DELTA 3 Plus (next-gen ~1 kWh mid): roughly double the nameplate Wh against a newer-generation mid box. “DELTA 3” search language usually resolves to DELTA 3 Plus on EcoFlow US cards — match the exact model. Feature-class honesty, not a winner crown. Prices: check current listing.
Honesty first (read this)
- No invented Wh, watts, or street prices. DELTA 2 Max figures reused from DELTA 2 Max vs DELTA Pro (EcoFlow US product page: 2,048 Wh LFP · 2,400 W / 4,800 W surge · 1,000 W solar · 23 kg). DELTA 3 Plus figures reused from DELTA 3 vs DELTA 2 (1,024 Wh · 1,800 W / 3,600 W surge · LFP). DELTA 3 Plus solar input, weight and UPS switchover: check listing.
- Wh is the job, not generation. If one ~1 kWh night already fits, the Max’s extra Wh is weight you carry; if a fridge weekend is the job, newer generation does not add Wh.
- Region SKUs move. Continuous / surge and solar input differ by region — confirm the model card. Price: Check current listing.
