What can it run, and for how long?
Estimates assume ~85% inverter efficiency and average running wattage. Motor-driven appliances also need surge headroom.
| Appliance | Typical draw | Estimated runtime |
|---|---|---|
| LED bulb | 10 W | 4 days |
| Wi-Fi router + modem | 15 W | 2 days |
| CPAP machine (no humidifier) | 40 W | 22 hours |
| Starlink (standard kit) | 50 W | 17 hours |
| Box fan | 50 W | 17 hours |
| Laptop | 60 W | 15 hours |
| 55" LED TV | 100 W | 8.7 hours |
| Full-size refrigerator (avg) | 150 W | 5.8 hours |
| Mini fridge (avg) | 60 W | 15 hours |
| Coffee maker | 900 W | 58 minutes |
| Microwave (700W cooking) | 1000 W | 52 minutes |
| Space heater | 1500 W | 35 minutes |
For CPAP users: that's roughly 2.7 nights of sleep (8h/night, humidifier off).

FAQ
How long will the EcoFlow DELTA 2 run a refrigerator?
Around 5.8 hours for a full-size refrigerator averaging 150W, assuming ~85% inverter efficiency. Actual runtime depends on the fridge's compressor duty cycle and ambient temperature.
Does the EcoFlow DELTA 2 use a LiFePO4 battery?
Yes. It uses LiFePO4 (LFP) cells rated for about 3,000 cycles to 80% capacity — roughly 8+ years of daily cycling.
What solar panels work with the EcoFlow DELTA 2?
Any panel (or array) within its 11-60V MPPT voltage window and up to 500W, connected via XT60. Staying inside the voltage window matters more than matching wattage.
How fast does the EcoFlow DELTA 2 recharge from a wall outlet?
About 50 minutes from 0 to 80% on AC power.
