The differences that matter
- Capacity, 3.2 kWh vs 2.048 kWh → at the same load and ignoring losses, the Elite 320 runs roughly one and a half times as long.
- Continuous output, 1800 W vs 3000 W → the DELTA 3 Max Plus takes a higher combined load before it reaches its rated limit.
- Maximum charge power, 1.44 kW vs 2.3 kW → in theory a full recharge takes about 2 h 15 min against just under an hour (at maximum power, no losses).
- Warranty, 5 years vs 3 → the Elite 320 stays covered two years longer.
Which one to choose
Choose BLUETTI Elite 320 if…
you expect long outages and keep the unit somewhere cold, such as an unheated garage or cellar: it is rated down to -20 °C, against -10 °C. You accept 34 kg to move around, against 22 kg, along with lower output and slower charging.
Choose EcoFlow DELTA 3 Max Plus if…
you work from home and want laptop, monitor, phones and other devices plugged in directly: 4 AC sockets and 3 USB-C ports (up to 140 W). The trade-off is less energy in the battery, so the same outage is covered for fewer hours, and a shorter warranty. At 22 kg it is also easier to carry between rooms.
