Questions
How long will the EcoFlow DELTA 2 run a refrigerator?
About 16.6 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 run a microwave?
Yes. A 1,000 W microwave draws around 1,500 W from the outlet, within its 1,800 W continuous output. Ten minutes of use takes about 29% of the battery.
How long does the EcoFlow DELTA 2 take to charge?
About 80 minutes from a wall outlet (manufacturer figure). With solar at its 500 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 use and how long will it last?
It uses LiFePO4 cells rated for 3,000 charge cycles, about 3,072 kWh of total delivered energy. LiFePO4 is the most durable common chemistry for power stations.
