Ranked #4 in Best Portable Generators
EcoFlow Delta 2 Max 2048Wh Power Station4.6
$1,899The EcoFlow Delta 2 Max is the battery power station that Digital Trends's Nick Mokey called 'the optimal choice for long-term power station ownership' and Bob Vila scored 9.4/10 for adaptability. Zero emissions, indoor-safe, charges to 80% in 1.1 hours, and its LFP battery is rated for 10 years of daily use. The right pick for short multi-hour outages and indoor backup where gas generators can't go.
Strengths
- — Indoor-safe operation with zero emissions — runs in basements, garages, and apartments where gas generators can't
- — Six AC outlets at 2,400W continuous output, more than any competitor in this capacity class
- — LFP (LiFePO4) battery chemistry rated for 3,000 cycles to 80% — roughly 10 years of daily use
Watch-outs
- — $1,899 MSRP is steep for 2kWh of capacity — a full-size refrigerator runs only 14 hours per charge
- — 50 lb weight is portable for one person but harder to move than a 25-lb battery station
- — X-Boost mode that reaches 3,400W reduces voltage on the receiving device — not suitable for resistive loads like space heaters or hair dryers
