Questions
How long will the EcoFlow DELTA Pro run a refrigerator?
About 2.4 days 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 Pro run a microwave?
Yes. A 1,000 W microwave draws around 1,500 W from the outlet, within its 3,600 W continuous output. Ten minutes of use takes about 8% of the battery.
How long does the EcoFlow DELTA Pro take to charge?
About 162 minutes from a wall outlet (manufacturer figure). With solar at its 1,600 W maximum input, a full charge takes about 2.3 hours of full sun, or about 3.2 hours at typical real-world panel output.
What battery does the EcoFlow DELTA Pro use and how long will it last?
It uses LiFePO4 cells rated for 3,500 charge cycles, about 12,600 kWh of total delivered energy. LiFePO4 is the most durable common chemistry for power stations.
