The differences that matter
- Capacity 3.014 vs 1.024 kWh → at the same load the BLUETTI stays on about three times as long.
- Continuous output 2,400 vs 1,800 W, peak 4,800 vs 3,000 W → continuous loads above 1,800 W need the BLUETTI.
- Solar input 1,200 vs 500 W → with panels the BLUETTI recharges much faster during the day.
- Warranty 2 vs 3 years → the DELTA 3 Classic is covered for one year longer.
Which one to choose
Choose BLUETTI Elite 300 if…
you need more reserve and more power: 3.014 kWh, 2,400 W continuous with 4,800 W peak and 1,200 W of solar input. The trade-off is 26.3 kg, 78 minutes for 0–80% and a 2-year warranty.
Choose EcoFlow DELTA 3 Classic if…
you move it often and 1.024 kWh is enough: 12.1 kg, 60 minutes for 0–80%, two USB-C and one USB-A, a 3-year warranty. You accept 1,800 W continuous (3,000 W peak) and 500 W of solar input.
