Our take
The EcoFlow DELTA 2 is the workhorse of the mid-size power-station class, pairing a long-life LiFePO4 (LFP) battery with a genuinely fast charging system that hits roughly 80% in under 50 minutes from a wall outlet. Its 1800W AC output (2700W X-Boost surge) runs most household essentials during outages, and the modular ecosystem lets you bolt on an extra battery to reach 2048Wh or feed it with EcoFlow or third-party solar panels up to 500W. At ~10kg it is heavier than a compact unit but still manageable for one person, and the app gives clean control over charge rates and pass-through. It is one of the most cross-shopped backup units of 2025-2026 and a sensible default for home backup, RVs, and camping.
What we like
- LiFePO4 cells rated for 3000+ cycles, far outlasting older lithium-ion stations
- Extremely fast wall recharge (about 80% in under 50 minutes)
- Expandable to 2048Wh with an add-on battery and accepts up to 500W solar input
- 1800W AC output (2700W surge) handles most home essentials
What to keep in mind
- Heavier (~27 lb) than ultra-portable competitors
- Solar panels are sold separately, raising the true off-grid cost
- Fan can be audible under heavy load or fast charging
