The differences that matter
- 1.024 against 2.048 kWh, up to 6.144 expanded → under the same load the second lasts about twice as long.
- 12 against 23 kg → one is carried with a single hand, the other rarely moves.
- 1800 W, 2700 peak, against 2400 W, 4800 peak → the second starts harder loads and carries more at once.
- 1.2 kW and 500 W solar against 2.4 kW and 1000 W → the second recharges in far less time.
Which one to choose
Choose EcoFlow DELTA 2 if…
you carry it often, to the car or onto a boat, and phones, a laptop, lights and a small appliance up to 1800 W are enough. It weighs 12 kg. The trade-off: 1.024 kWh runs out quickly under a heavy load, the peak is 2700 W and recharging is slow, 1.2 kW from the mains and up to 500 W from panels.
Choose EcoFlow DELTA 2 Max if…
you want a real reserve at home, with loads up to 2400 W and a 4800 W peak, that recharges fast between outages: 2.4 kW from the mains and up to 1000 W from panels. It can be taken to 6.144 kWh with extra batteries. What you accept: 23 kg, so it stays where you put it.
