BLUETTI Elite 320 vs EcoFlow DELTA 2 Max
Technical comparison · Home backup
Two home LFP power stations aiming at different things: the Elite 320 has more energy, 3.2 kWh, while the DELTA 2 Max has more power and recharges faster. Anyone who wants reserve and an uninterrupted handover looks at the first; anyone running heavy loads and refilling quickly looks at the second.

The differences that matter
- 3.2 against 2.048 kWh → the Elite 320 keeps the same devices running longer, at the cost of 11 kg more.
- 1800 against 2400 W continuous → above 1800 W the Elite 320 is not enough; the DELTA 2 Max goes to 2400 W.
- Maximum charging 1.44 against 2.4 kW → after a blackout the DELTA 2 Max is full again much sooner.
- UPS in 10 ms against EPS in 20 ms with a brief interruption → the switch to battery is faster on the Elite 320.

Which one to choose
Choose BLUETTI Elite 320 if…
the unit stays indoors as a reserve for long outages and sometimes rolls outside: it has a handle and wheels, switches over in 10 ms like a UPS and declares operation down to -20 °C. The trade-off is logistics: 34 kg and only two mains sockets, so few devices at a time, with a slower recharge after each use.
Choose EcoFlow DELTA 2 Max if…
you need more sockets and less weight: the DELTA 2 Max has four mains sockets, weighs 23 kg and declares 53 minutes from 0 to 80%. It can expand to 6.144 kWh if the starting reserve is not enough. The trade-off is the handover when mains drops: it switches in 20 ms, with a brief pause.
