Questions
How long will the EcoFlow DELTA 2 Max run a refrigerator?
About 33.2 h for a typical full-size fridge (150 W running, roughly 35% compressor duty cycle). Newer energy-efficient fridges will run longer.
Can the EcoFlow DELTA 2 Max run a microwave?
Yes. A 1,000 W microwave draws around 1,500 W from the outlet, within its 2,400 W continuous output. Ten minutes of use takes about 14% of the battery.
How long does the EcoFlow DELTA 2 Max take to charge?
With solar at its 1,000 W maximum input, a full charge takes about 2.0 hours of full sun, or about 2.9 hours at typical real-world panel output.
What battery does the EcoFlow DELTA 2 Max use and how long will it last?
It uses LiFePO4 cells rated for 3,000 charge cycles, about 6,144 kWh of total delivered energy. LiFePO4 is the most durable common chemistry for power stations.
